Key points about antidepressants Antidepressants are a group of medicines used to treat moderate to severe depression. Antidepressants work best when they are used together with psychological therapies, like CBT (cognitive behavioural therapy) and lifestyle changes. Read about how to take antidepressants safely and possible side effects. Antidepressants are medicines that are mainly used to treat moderate to severe depression. They can help improve mood and increase motivation for people who may have lost interest in activities they once enjoyed. They can also help with sleep, thinking and concentration. Antidepressants work best when they are used together with psychological therapies, like CBT (cognitive behavioural therapy) and lifestyle changes. Read more about treating depression .  Antidepressants are not usually needed, and are often not very effective for mild depression. CBT ,  talking   therapy  and regular exercise work better for mild depression. Antidepressants are also used to treat other conditions such as generalised anxiety disorder (GAD) ,  eating disorders , obsessive-compulsive disorder and post-traumatic stress disorder . They are also sometimes used to treat people with long-term (chronic) pain.

There are many types of antidepressants. Different medicines suit different people. The choice of antidepressant medicine will depend on: the severity and type of your illness whether you have other medical conditions other medicines you might be taking your response to antidepressant medicines in the past possible side effects.    Antidepressants available in Aotearoa New Zealand Selective serotonin reuptake inhibitors (SSRIs) Examples include fluoxetine ,  sertraline ,  paroxetine , citalopram  and escitalopram . SSRIs are usually the preferred antidepressant for moderate to severe depression. Overall they have fewer side effects than the other types of antidepressants. Read more about SSRIs. Serotonin and noradrenaline reuptake inhibitors (SNRIs) An example is  venlafaxine. Venlafaxine is often used when SSRIs haven't been successful. Tricyclic antidepressants (TCAs) Examples include  amitriptyline , clomipramine, dosulepin,  imipramine , and   nortriptyline.  TCAs aren't usually used for their antidepressant effects due to their side effects. They're most often used for other conditions such as neuropathic pain  and anxiety.  Monoamine-oxidase inhibitors   Examples are moclobemide and tranylcypromine. MAOIs are rarely used due to their side effects and the number of interactions with medicines and foods. Other antidepressants Mirtazapine Some people find that herbal products like St John's Wort can be useful for depression but it can interact with antidepressant medicines and other medicines. Before taking herbal supplements, ask your doctor or pharmacist if they interact with the medicine you are taking. We don't know for certain, but researchers think that antidepressants work by increasing the activity of certain chemicals working in our brains called neurotransmitters. Certain neurotransmitters, such as serotonin and noradrenaline, are linked to mood and emotion. While depression is not simply a deficiency of these chemicals, we do know that antidepressant medications help to relieve symptoms of depression and anxiety in about 50–70% of people who try them. S ome people will respond to one antidepressant better than another so changes may be needed to find the best type and dose of medicine for you.   Neurotransmitters may also affect pain signals sent by nerves, which would explain why some antidepressants can help relieve long-term pain. Antidepressant medicines work best if you take them every day. When you first start taking an antidepressant medicine, you won’t feel better straight away. Most people start to feel better after taking them for 2 to 4 weeks. However, it can take up to 6 to 8 weeks for them to really work. How long you need to take antidepressants for will depend on a number of factors and is best discussed with your doctor. Most people will need to take these medicines for at least 6 to 12 months. If you stop taking it too early, your signs of depression or anxiety may come back. During the first few months of treatment, you'll usually see your doctor or a specialist nurse at least once every few weeks to see how well the medicine is working. If you're ready to come off your antidepressant medicine, or think it isn't working for you, don't stop taking it suddenly. The dose of these medicines should be slowly reduced over 4 weeks or more. Some people get withdrawal symptoms when they try to reduce or stop taking an antidepressant.  Withdrawal symptoms can be different for everyone. They usually come on within 5 days of stopping the medicine and generally last 1 to 2 weeks. Some people have severe withdrawal symptoms that last for several months or more. If you have taken a high dose of antidepressants for a long time you are more likely to have withdrawal symptoms. Some antidepressants are more likely to cause withdrawal symptoms, eg,   amitriptyline, clomipramine, paroxetine and venlafaxine. Talk to your doctor about how to stop taking your medicine slowly. They will work out a plan with you. They will slowly lower the amount you take over several weeks until you’re not taking it at all. This lowers the chance of getting withdrawal symptoms as you stop taking it. Withdrawal may include feeling dizzy, tired or worried, or having trouble sleeping.

(external link)   Talk to your doctor or your healthcare team if you are stopping your medicine and feel like you might harm yourself or others, or if your low mood or anxiety returns. Like all medicines antidepressants can cause side effects but not everyone gets them. Different antidepressants have different side effects. Most side effects are mild and go away after a few weeks as your body gets used to the medicine. Examples include having trouble sleeping (insomnia), feeling like you might throw up (nausea) and feeling dizzy. At the start of treatment some people can experience side effects such as agitation and anxiety, especially in the first few weeks. Keep in mind that things will get better and these side effects are likely to pass as your body gets used to the new medicine. Talk to your healthcare provider about what you can do if side effects are a problem or if you think you might harm yourself or others. They may suggest taking a smaller dose (amount) or trying a different medicine. Read more about medicines and side effects and reporting a reaction you think might be a side effect .

Antidepressants are medicines that are mainly used to treat moderate to severe depression. They can help improve mood and increase motivation for people who may have lost interest in activities they once enjoyed. They can also help with sleep, thinking and concentration. Antidepressants work best when they are used together with psychological therapies, like CBT (cognitive behavioural therapy) and lifestyle changes. Read more about [treating depression](https://healthify.nz/health-a-z/d/depression-overview). Antidepressants are not usually needed, and are often not very effective for mild depression. [CBT](https://healthify.nz/health-a-z/c/cognitive-behavioural-therapy), talking therapy and regular exercise work better for mild depression. Antidepressants are also used to treat other conditions such as [generalised anxiety disorder (GAD)](https://healthify.nz/health-a-z/a/anxiety "Anxiety"), [eating disorders](https://healthify.nz/health-a-z/e/eating-disorders "Eating disorders"), [obsessive-compulsive disorder](https://healthify.nz/health-a-z/o/obsessive-compulsive-disorder "Obsessive compulsive disorder") and [post-traumatic stress disorder](https://healthify.nz/health-a-z/p/post-traumatic-stress-disorder-ptsd "Post-traumatic stress disorder (PTSD)"). They are also sometimes used to treat people with long-term (chronic) pain. ![Young man talking to GP ](https://healthify.nz/assets/Card-Images/woman-talking-to-gp-665x443-1-v2.jpg) *Image credit: 123RF* #### I need help with my mental health **If you need help or want to talk to somebody about your mental health, you can get support from any of the following:** - **Free call or text 1737** any time for support from a trained counsellor - **Lifeline** 0800 543 354 (0800 LIFELINE) or free text 4357 (HELP) - **Suicide Crisis Helpline** 0508 828 865 (0508 TAUTOKO) - **Healthline** 0800 611 116 - **Samaritans** 0800 726 666. #### What to consider when choosing an antidepressant There are many types of antidepressants. Different medicines suit different people. The choice of antidepressant medicine will depend on: - the severity and type of your illness - whether you have other medical conditions - other medicines you might be taking - your response to antidepressant medicines in the past - possible side effects. | **Antidepressants available in Aotearoa New Zealand** | |---| | **Selective serotonin reuptake inhibitors (SSRIs)** Examples include [fluoxetine](https://healthify.nz/medicines-a-z/f/fluoxetine "Fluoxetine"), [sertraline](https://healthify.nz/medicines-a-z/s/sertraline "Sertraline"), [paroxetine](https://healthify.nz/medicines-a-z/p/paroxetine "Paroxetine"), [citalopram](https://healthify.nz/medicines-a-z/c/citalopram "Citalopram") and [escitalopram](https://healthify.nz/medicines-a-z/e/escitalopram "Escitalopram"). SSRIs are usually the preferred antidepressant for moderate to severe depression. Overall they have fewer side effects than the other types of antidepressants. Read more about [SSRIs.](https://healthify.nz/medicines-a-z/s/ssri-antidepressants "SSRI antidepressants") | | **Serotonin and noradrenaline reuptake inhibitors (SNRIs)** An example is [venlafaxine.](https://healthify.nz/medicines-a-z/v/venlafaxine "Venlafaxine") Venlafaxine is often used when SSRIs haven't been successful. | | **Tricyclic antidepressants (TCAs)** Examples include [amitriptyline](https://healthify.nz/medicines-a-z/a/amitriptyline "Amitriptyline"), clomipramine, dosulepin, [imipramine](https://healthify.nz/medicines-a-z/i/imipramine "Imipramine"), and nortriptyline. TCAs aren't usually used for their antidepressant effects due to their side effects. They're most often used for other conditions such as [neuropathic pain](https://healthify.nz/health-a-z/n/nerve-pain "Nerve pain") and anxiety. | | **Monoamine-oxidase inhibitors** Examples are moclobemide and tranylcypromine. MAOIs are rarely used due to their side effects and the number of interactions with medicines and foods. | | **Other antidepressants** [Mirtazapine](https://healthify.nz/medicines-a-z/m/mirtazapine "Mirtazapine") | #### Can I use herbal supplements when taking antidepressants? Some people find that herbal products like [St John's Wort](https://healthify.nz/medicines-a-z/s/st-john-s-wort "St John’s wort") can be useful for depression but it can interact with antidepressant medicines and other medicines. Before taking herbal supplements, ask your doctor or pharmacist if they interact with the medicine you are taking. #### How do antidepressants work? We don't know for certain, but researchers think that antidepressants work by increasing the activity of certain chemicals working in our brains called neurotransmitters. Certain neurotransmitters, such as serotonin and noradrenaline, are linked to mood and emotion. While depression is not simply a deficiency of these chemicals, we do know that antidepressant medications help to relieve symptoms of depression and anxiety in about 50–70% of people who try them. Some people will respond to one antidepressant better than another so changes may be needed to find the best type and dose of medicine for you. Neurotransmitters may also affect pain signals sent by nerves, which would explain why some antidepressants can help relieve long-term pain. #### How long will I need to take antidepressants for? Antidepressant medicines work best if you take them every day. When you first start taking an antidepressant medicine, you won’t feel better straight away. Most people start to feel better after taking them for 2 to 4 weeks. However, it can take up to 6 to 8 weeks for them to really work. How long you need to take antidepressants for will depend on a number of factors and is best discussed with your doctor. Most people will need to take these medicines for at least 6 to 12 months. If you stop taking it too early, your signs of depression or anxiety may come back. During the first few months of treatment, you'll usually see your doctor or a specialist nurse at least once every few weeks to see how well the medicine is working. #### Don't stop taking your antidepressant medicine suddenly If you're ready to come off your antidepressant medicine, or think it isn't working for you, don't stop taking it suddenly. The dose of these medicines should be slowly reduced over 4 weeks or more. - Some people get withdrawal symptoms when they try to reduce or stop taking an antidepressant. - Withdrawal symptoms can be different for everyone. They usually come on within 5 days of stopping the medicine and generally last 1 to 2 weeks. Some people have severe withdrawal symptoms that last for several months or more. - If you have taken a high dose of antidepressants for a long time you are more likely to have withdrawal symptoms. Some antidepressants are more likely to cause withdrawal symptoms, eg, amitriptyline, clomipramine, paroxetine and venlafaxine. Talk to your doctor about how to stop taking your medicine slowly. They will work out a plan with you. They will slowly lower the amount you take over several weeks until you’re not taking it at all. This lowers the chance of getting withdrawal symptoms as you stop taking it. Withdrawal may include feeling dizzy, tired or worried, or having trouble sleeping. Read more about [stopping antidepressants.(external link)](https://www.medsafe.govt.nz/Consumers/educational-material/Stopping-Antidepressant-medicines.pdf "Open external link") Talk to your doctor or your healthcare team if you are stopping your medicine and feel like you might harm yourself or others, or if your low mood or anxiety returns. #### What to know about the side effects of antidepressants Like all medicines antidepressants can cause side effects but not everyone gets them. Different antidepressants have different side effects. Most side effects are mild and go away after a few weeks as your body gets used to the medicine. Examples include having trouble sleeping (insomnia), feeling like you might throw up (nausea) and feeling dizzy. At the start of treatment some people can experience side effects such as agitation and anxiety, especially in the first few weeks. Keep in mind that things will get better and these side effects are likely to pass as your body gets used to the new medicine. Talk to your healthcare provider about what you can do if side effects are a problem or if you think you might harm yourself or others. They may suggest taking a smaller dose (amount) or trying a different medicine.

### Key points about antidepressants - Antidepressants are a group of medicines used to treat moderate to severe depression. - Antidepressants work best when they are used together with psychological therapies, like CBT (cognitive behavioural therapy) and lifestyle changes. - Read about how to take antidepressants safely and possible side effects. ![HN 0789 female pharmacist working in dispensary of community pharmacy 1](https://healthify.nz/assets/Health-A-Z/Medicines/HN-0789-female-pharmacist-working-in-dispensary-of-community-pharmacy-1.jpg) Antidepressants are medicines that are mainly used to treat moderate to severe depression. They can help improve mood and increase motivation for people who may have lost interest in activities they once enjoyed. They can also help with sleep, thinking and concentration. Antidepressants work best when they are used together with psychological therapies, like CBT (cognitive behavioural therapy) and lifestyle changes. Read more about [treating depression](https://healthify.nz/health-a-z/d/depression-overview). Antidepressants are not usually needed, and are often not very effective for mild depression. [CBT](https://healthify.nz/health-a-z/c/cognitive-behavioural-therapy), talking therapy and regular exercise work better for mild depression. Antidepressants are also used to treat other conditions such as [generalised anxiety disorder (GAD)](https://healthify.nz/health-a-z/a/anxiety "Anxiety"), [eating disorders](https://healthify.nz/health-a-z/e/eating-disorders "Eating disorders"), [obsessive-compulsive disorder](https://healthify.nz/health-a-z/o/obsessive-compulsive-disorder "Obsessive compulsive disorder") and [post-traumatic stress disorder](https://healthify.nz/health-a-z/p/post-traumatic-stress-disorder-ptsd "Post-traumatic stress disorder (PTSD)"). They are also sometimes used to treat people with long-term (chronic) pain. ![Young man talking to GP ](https://healthify.nz/assets/Card-Images/woman-talking-to-gp-665x443-1-v2.jpg) *Image credit: 123RF* **If you need help or want to talk to somebody about your mental health, you can get support from any of the following:** - **Free call or text 1737** any time for support from a trained counsellor - **Lifeline** 0800 543 354 (0800 LIFELINE) or free text 4357 (HELP) - **Suicide Crisis Helpline** 0508 828 865 (0508 TAUTOKO) - **Healthline** 0800 611 116 - **Samaritans** 0800 726 666. There are many types of antidepressants. Different medicines suit different people. The choice of antidepressant medicine will depend on: - the severity and type of your illness - whether you have other medical conditions - other medicines you might be taking - your response to antidepressant medicines in the past - possible side effects. | **Antidepressants available in Aotearoa New Zealand** | |---| | **Selective serotonin reuptake inhibitors (SSRIs)** Examples include [fluoxetine](https://healthify.nz/medicines-a-z/f/fluoxetine "Fluoxetine"), [sertraline](https://healthify.nz/medicines-a-z/s/sertraline "Sertraline"), [paroxetine](https://healthify.nz/medicines-a-z/p/paroxetine "Paroxetine"), [citalopram](https://healthify.nz/medicines-a-z/c/citalopram "Citalopram") and [escitalopram](https://healthify.nz/medicines-a-z/e/escitalopram "Escitalopram"). SSRIs are usually the preferred antidepressant for moderate to severe depression. Overall they have fewer side effects than the other types of antidepressants. Read more about [SSRIs.](https://healthify.nz/medicines-a-z/s/ssri-antidepressants "SSRI antidepressants") | | **Serotonin and noradrenaline reuptake inhibitors (SNRIs)** An example is [venlafaxine.](https://healthify.nz/medicines-a-z/v/venlafaxine "Venlafaxine") Venlafaxine is often used when SSRIs haven't been successful. | | **Tricyclic antidepressants (TCAs)** Examples include [amitriptyline](https://healthify.nz/medicines-a-z/a/amitriptyline "Amitriptyline"), clomipramine, dosulepin, [imipramine](https://healthify.nz/medicines-a-z/i/imipramine "Imipramine"), and nortriptyline. TCAs aren't usually used for their antidepressant effects due to their side effects. They're most often used for other conditions such as [neuropathic pain](https://healthify.nz/health-a-z/n/nerve-pain "Nerve pain") and anxiety. | | **Monoamine-oxidase inhibitors** Examples are moclobemide and tranylcypromine. MAOIs are rarely used due to their side effects and the number of interactions with medicines and foods. | | **Other antidepressants** [Mirtazapine](https://healthify.nz/medicines-a-z/m/mirtazapine "Mirtazapine") | Some people find that herbal products like [St John's Wort](https://healthify.nz/medicines-a-z/s/st-john-s-wort "St John’s wort") can be useful for depression but it can interact with antidepressant medicines and other medicines. Before taking herbal supplements, ask your doctor or pharmacist if they interact with the medicine you are taking. We don't know for certain, but researchers think that antidepressants work by increasing the activity of certain chemicals working in our brains called neurotransmitters. Certain neurotransmitters, such as serotonin and noradrenaline, are linked to mood and emotion. While depression is not simply a deficiency of these chemicals, we do know that antidepressant medications help to relieve symptoms of depression and anxiety in about 50–70% of people who try them. Some people will respond to one antidepressant better than another so changes may be needed to find the best type and dose of medicine for you. Neurotransmitters may also affect pain signals sent by nerves, which would explain why some antidepressants can help relieve long-term pain. Antidepressant medicines work best if you take them every day. When you first start taking an antidepressant medicine, you won’t feel better straight away. Most people start to feel better after taking them for 2 to 4 weeks. However, it can take up to 6 to 8 weeks for them to really work. How long you need to take antidepressants for will depend on a number of factors and is best discussed with your doctor. Most people will need to take these medicines for at least 6 to 12 months. If you stop taking it too early, your signs of depression or anxiety may come back. During the first few months of treatment, you'll usually see your doctor or a specialist nurse at least once every few weeks to see how well the medicine is working. If you're ready to come off your antidepressant medicine, or think it isn't working for you, don't stop taking it suddenly. The dose of these medicines should be slowly reduced over 4 weeks or more. - Some people get withdrawal symptoms when they try to reduce or stop taking an antidepressant. - Withdrawal symptoms can be different for everyone. They usually come on within 5 days of stopping the medicine and generally last 1 to 2 weeks. Some people have severe withdrawal symptoms that last for several months or more. - If you have taken a high dose of antidepressants for a long time you are more likely to have withdrawal symptoms. Some antidepressants are more likely to cause withdrawal symptoms, eg, amitriptyline, clomipramine, paroxetine and venlafaxine. Talk to your doctor about how to stop taking your medicine slowly. They will work out a plan with you. They will slowly lower the amount you take over several weeks until you’re not taking it at all. This lowers the chance of getting withdrawal symptoms as you stop taking it. Withdrawal may include feeling dizzy, tired or worried, or having trouble sleeping. Read more about [stopping antidepressants.(external link)](https://www.medsafe.govt.nz/Consumers/educational-material/Stopping-Antidepressant-medicines.pdf "Open external link") Talk to your doctor or your healthcare team if you are stopping your medicine and feel like you might harm yourself or others, or if your low mood or anxiety returns. Like all medicines antidepressants can cause side effects but not everyone gets them. Different antidepressants have different side effects. Most side effects are mild and go away after a few weeks as your body gets used to the medicine. Examples include having trouble sleeping (insomnia), feeling like you might throw up (nausea) and feeling dizzy. At the start of treatment some people can experience side effects such as agitation and anxiety, especially in the first few weeks. Keep in mind that things will get better and these side effects are likely to pass as your body gets used to the new medicine. Talk to your healthcare provider about what you can do if side effects are a problem or if you think you might harm yourself or others. They may suggest taking a smaller dose (amount) or trying a different medicine.
