What do I need to know about melatonin side effects? ~ No name \/ No state given\nAnswer\nThe hormone melatonin helps control your natural sleep-wake cycle. In fact, natural levels of melatonin in the blood are highest just before bedtime. If you're struggling with insomnia, melatonin supplements may help you fall asleep or stay asleep. However, there are no guarantees. Most studies show melatonin to be only minimally effective for insomnia. Melatonin may play a stronger role in fighting jet lag. Melatonin side effects may include daytime sleepiness, dizziness, headaches and abdominal discomfort. Confusion, sleepwalking or nightmares also are possible. Some studies suggest that melatonin increases the risk of seizures, but others disagree. Melatonin may interact with various medications. The optimal dose of melatonin isn't certain, and the long-term effects are unknown. Talk to your doctor before taking melatonin, especially if you have any underlying health conditions. If you decide to take melatonin, make sure the supplements are manufactured in a lab, not derived from animals.\n#2\nI never gave much thought to the use of melatonin, expecting it to be fairly benign.   If Forum members have had experience, whether favorable or disappointing, it would be interesting to hear your comments on the effectiveness of melatonin from your own experience\nHowever David's posting, David raises a few red flags, particularly in connection with possible drug interactions, which I would like to address:\nGENERIC NAME: MELATONIN - ORAL\nUSES:\nMelatonin has been used for sleep disorders (e.g., insomnia and jet lag).

I have heard that melatonin shouldn't be taken regularly by young people (under 35), unless recommended by a doctor since the body normally produces enough melatonin and taking a supplement regularly could cause an overdose. But I know as a person ages, melatonin levels decrease, so it can be helpful for the elderly who have difficulty sleeping. I think for those people, it's a good alternative to a prescription.\n\nLast edited by a moderator:\n\nDec 9, 2008\n\n- [Jul 8, 2009](https:\/\/forum.psychlinks.ca\/threads\/melatonin-side-effects-what-are-the-risks.7353\/post-59890)\n\n- [\\#4](https:\/\/forum.psychlinks.ca\/threads\/melatonin-side-effects-what-are-the-risks.7353\/post-59890)\n\n[![Mustang](https:\/\/forum.psychlinks.ca\/data\/avatars\/m\/2\/2871.jpg?1612293987)](https:\/\/forum.psychlinks.ca\/members\/mustang.2871\/)\n\n#### [Mustang](https:\/\/forum.psychlinks.ca\/members\/mustang.2871\/)\n**Member**\n\nI've taken Melatonin, occasionally, i've found it helps a bit fro one night but i've that subsequent nights it doesn't seem to work at all.\n\n- [Sep 12, 2012](https:\/\/forum.psychlinks.ca\/threads\/melatonin-side-effects-what-are-the-risks.7353\/post-59891)\n\n- [\\#5](https:\/\/forum.psychlinks.ca\/threads\/melatonin-side-effects-what-are-the-risks.7353\/post-59891)\n\n[D](https:\/\/forum.psychlinks.ca\/members\/darkside.4767\/)\n\n#### [Darkside](https:\/\/forum.psychlinks.ca\/members\/darkside.4767\/)\n**MVP**\n\nI took it to help me stop Klonopin.

risks?](http:\/\/www.mayoclinic.com\/health\/melatonin-side-effects\/AN01717)  \n By Mayo Clinic Staff   \n Oct 18, 2007\n\n*I'm considering taking melatonin to help me sleep. What do I need to know about melatonin side effects? ~ No name \/ No state given*\n\n**Answer**  \n The hormone melatonin helps control your natural sleep-wake cycle. In fact, natural levels of melatonin in the blood are highest just before bedtime. If you're struggling with insomnia, melatonin supplements may help you fall asleep or stay asleep. However, there are no guarantees. Most studies show melatonin to be only minimally effective for insomnia. Melatonin may play a stronger role in fighting jet lag. Melatonin side effects may include daytime sleepiness, dizziness, headaches and abdominal discomfort. Confusion, sleepwalking or nightmares also are possible. Some studies suggest that melatonin increases the risk of seizures, but others disagree. Melatonin may interact with various medications. The optimal dose of melatonin isn't certain, and the long-term effects are unknown. Talk to your doctor before taking melatonin, especially if you have any underlying health conditions. If you decide to take melatonin, make sure the supplements are manufactured in a lab, not derived from animals.\n\n- [\\#2](https:\/\/forum.psychlinks.ca\/threads\/melatonin-side-effects-what-are-the-risks.7353\/post-59888)\n\nI never gave much thought to the use of melatonin, expecting it to be fairly benign.

I have heard that melatonin shouldn't be taken regularly by young people (under 35), unless recommended by a doctor since the body normally produces enough melatonin and taking a supplement regularly could cause an overdose. But I know as a person ages, melatonin levels decrease, so it can be helpful for the elderly who have difficulty sleeping. I think for those people, it's a good alternative to a prescription.

What do I need to know about melatonin side effects? ~ No name / No state given Answer The hormone melatonin helps control your natural sleep-wake cycle. In fact, natural levels of melatonin in the blood are highest just before bedtime. If you're struggling with insomnia, melatonin supplements may help you fall asleep or stay asleep. However, there are no guarantees. Most studies show melatonin to be only minimally effective for insomnia. Melatonin may play a stronger role in fighting jet lag. Melatonin side effects may include daytime sleepiness, dizziness, headaches and abdominal discomfort. Confusion, sleepwalking or nightmares also are possible. Some studies suggest that melatonin increases the risk of seizures, but others disagree. Melatonin may interact with various medications. The optimal dose of melatonin isn't certain, and the long-term effects are unknown. Talk to your doctor before taking melatonin, especially if you have any underlying health conditions. If you decide to take melatonin, make sure the supplements are manufactured in a lab, not derived from animals. - [\#2](https://forum.psychlinks.ca/threads/melatonin-side-effects-what-are-the-risks.7353/post-59888) I never gave much thought to the use of melatonin, expecting it to be fairly benign. If Forum members have had experience, whether favorable or disappointing, it would be interesting to hear your comments on the effectiveness of melatonin from your own experience However David's posting, David raises a few red flags, particularly in connection with possible drug interactions, which I would like to address: GENERIC NAME: MELATONIN - ORAL USES: Melatonin has been used for sleep disorders (e.g., insomnia and jet lag).
