tasimelteon

Take tasimelteon (Hetlioz) at the same time every night to maintain a regular sleep cycle. If you can't take it at the usual time one night, skip that dose and take the next one at your regular time the following night. This way, the medication can keep working properly.

Take tasimelteon (Hetlioz) on an empty stomach 1 hour before bedtime. This helps your body absorb the medication faster so that you can fall asleep sooner. Taking it with food can reduce how much medication your body absorbs and potentially delay when it starts working.

Once you take tasimelteon (Hetlioz), focus only on preparing for bed. The medication might affect your ability to stay fully alert, so avoid doing anything that needs full concentration.

Tasimelteon (Hetlioz) works to correct sleep rhythm gradually. It can take weeks or months before you notice any improvements in your sleep. Continue taking the medication unless your prescriber says otherwise.

If you smoke tobacco, tasimelteon (Hetlioz) might not work as well because smoking can reduce the amount of medication in your body. Speak with your prescriber if you have questions about quitting smoking.

Keep tasimelteon (Hetlioz) capsules at room temperature, away from light and moisture. Store Hetlioz LQ liquid suspension in the refrigerator.

Shake the bottle well for at least 30 seconds before each use. If it’s your first time using the bottle, take off the seal and press the provided adapter into the neck of the bottle until it’s even with the top of the bottle. Once the adapter is attached, don’t remove it.

After attaching the adapter, shake the bottle again. Turn it upside down and use the provided syringe to measure the prescribed dose. When finished, leave the adapter on, replace the cap, and store the bottle in the refrigerator.

Write the date you open the bottle. Throw out the 48-mL bottle after 5 weeks and the 158-mL bottle after 8 weeks, even if there’s leftover medication.
