8. Melatonin Can Have Side Effects
Although melatonin appears to be safe and is not habit-forming, it may have some negative side effects. According to the Mayo Clinic, the most common side effects of melatonin usage are headache, dizziness, nausea, and daytime grogginess. Less common side effects are depression, tremor, anxiety, stomach cramps, irritability, and confusion. Some users may experience low blood pressure when taking this supplement. Since melatonin can result in daytime sleepiness, you should not operate machinery or drive a car within five hours of taking it.
7. Melatonin Can Interact with Other Medications
Several prescription medications may have drug interactions with melatonin supplements. These include medications that are metabolized by the liver, such as certain antidepressants, muscle relaxants, and anti-anxiety medications. Melatonin may also interact with certain blood pressure medications, immunosuppressants, and seizure medications. Since melatonin can cause decreased blood clotting, it can have effects on bleeding and bruising when taken along with blood thinners. Additionally, melatonin can increase the stimulant properties and side effects of methamphetamines. If you are taking prescription medications, talk with your doctor before using melatonin supplements.
6. Melatonin Is Not Appropriate for Children
Supplementation with melatonin products is not recommended for children, as it may interfere with their development. Since the effects of supplemental melatonin on the hormones and reproductive development of puberty are unknown, it is best to avoid the use of melatonin in this age group. One exception is the use of melatonin for disorders such as autism spectrum disorder if the benefits have been found to outweigh the risks.Related: Can’t Sleep? Try These 10 Vitamins
