Tasimelteon

Tasimelteon is a prescription medicine used to treat adults with non-24-hour sleep-wake disorder (Non-24). Non-24 is a disorder in which a person's sleep-wake cycle is longer than 24 hours. Symptoms of Non-24 may include difficulty falling asleep and staying asleep at the desired time. Tasimelteon helps regulate the sleep-wake cycle by resetting the body's internal clock to the desired sleep-wake schedule.

Tasimelteon is a prescription medication sold under the brand name Hetlioz. It's specifically designed to target sleep issues, not a general purpose medication. Here's a breakdown of its key points:

Type of Drug:

• Tasimelteon belongs to a unique class of drugs called melatonin receptor agonists.

Function:

• It works by mimicking the effects of melatonin, a natural hormone produced in the body that helps regulate sleep-wake cycles.

Use:

• Tasimelteon is specifically approved for treating non-24-hour sleep-wake disorder (N24SWD) in adults with total blindness.
  • N24SWD is a circadian rhythm sleep disorder where the internal body clock is out of sync with the external light-dark cycle. People with N24SWD may experience difficulty falling asleep at night and staying asleep, or they may have a sleep schedule that shifts later and later each day.

How it Works:

• Tasimelteon binds to melatonin receptors in the brain, essentially acting like melatonin itself.
• This helps regulate the sleep-wake cycle and promotes nighttime sleep in individuals with N24SWD.

Dosage and Administration:

• Tasimelteon comes as a capsule taken orally, typically once a night about two hours before bedtime.
• The exact dosage is determined by your doctor based on individual factors.

Side Effects:

• Common side effects include headache, dizziness, nausea, and fatigue.
• Less common side effects may include depression, anxiety, and changes in taste.
