  • Shift work sleep disorder
  • Delayed sleep phase syndrome
  • Sleep disturbances in children with autism spectrum disorders
  • Insomnia related to attention deficit hyperactivity disorder (ADHD)
  • Cluster headaches

Melatonin Recall

There have been instances where certain melatonin products have been recalled due to quality concerns. It is important to purchase melatonin from reputable sources and to check for any recalls or safety alerts before use.

Melatonin FDA Approval

Melatonin is classified as a dietary supplement by the U.S. Food and Drug Administration (FDA). Unlike prescription medications, dietary supplements do not require FDA approval before they can be marketed and sold. However, the FDA does regulate the manufacturing and labeling of dietary supplements to ensure their safety.

How Should Melatonin be Used?

Melatonin is available in various forms, including tablets, capsules, and liquid. The appropriate dosage and timing of melatonin may vary depending on the individual and the specific sleep disorder being treated. It is important to follow the instructions provided by a healthcare professional or the product label.

Other Uses for Melatonin

While melatonin is primarily used for sleep disorders, some individuals may use it for other purposes. These off-label uses include:

  • Reducing symptoms of seasonal affective disorder (SAD)
  • Managing symptoms of tinnitus
  • Supporting healthy aging
  • Improving symptoms of certain neurological conditions

Special Precautions for Melatonin

It is important to take certain precautions when using melatonin. These include:

  • Using melatonin for short-term use only, unless otherwise directed by a healthcare professional

Storage and Disposal of Melatonin

Melatonin should be stored in a cool, dry place away from direct sunlight. It is important to keep it out of reach of children. If you no longer need to use melatonin or if it has expired, it should be disposed of properly according to local regulations.

In Case of Emergency/Overdose

If you suspect an overdose or experience severe symptoms after taking melatonin, seek immediate medical attention or contact a poison control center. Symptoms of overdose may include dizziness, nausea, vomiting, and rapid heartbeat.

Other Important Information about Melatonin

While melatonin is generally safe for short-term use, it is important to consult with a healthcare professional before starting any new medication or supplement. They can provide personalized advice based on your specific needs and medical history.

Remember, melatonin is not a substitute for good sleep hygiene practices. It is important to maintain a regular sleep schedule, create a comfortable sleep environment, and practice relaxation techniques to promote healthy sleep.

Always consult with a healthcare professional for guidance on using melatonin or any other medication or supplement.
