How to use Belsomra:
Use Belsomra as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Belsomra comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get Belsomra refilled.
- Belsomra may be taken with or without a meal. If taken with or right after a meal, it may take longer to work.
- Belsomra works very quickly; use Belsomra within 30 minutes of going to sleep.
- Use Belsomra only when you are able to get a full night's sleep (at least 7 hours).
- Check with your doctor before you eat grapefruit or drink grapefruit juice while you use Belsomra.
- If you miss a dose of Belsomra and you are taking it regularly, take it as soon as possible. If you will not be able to get a full nights sleep (at least 7 hours) after taking the missed dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once. Do not take more than 1 time each night.
Ask your health care provider any questions you may have about how to use Belsomra.
Important safety information:
- Belsomra may cause drowsiness. These effects may be worse if you take it with alcohol or certain medicines. Use Belsomra with caution. Do not drive or perform other possibly unsafe tasks within 8 hours of taking Belsomra and until you feel fully awake.
- Do not drink alcohol while you are using Belsomra. Do not take Belsomra if you drank alcohol the same evening or before bed.
- Check with your doctor before you use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are using Belsomra; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.
- Belsomra may affect how awake you feel during the day, even if you take it as your doctor has told you. This can affect driving skills and may increase the risk of falling asleep while driving. The risk of feeling sleepy the next day is increased if you take Belsomra with less than a full night's sleep (at least 7 hours), with higher doses, or with certain other medicines.
- Belsomra is usually used only for a short period of time. If your symptoms do not get better within 7 to 10 days or if they get worse, check with your doctor.
- Do NOT take more than the recommended dose or use for longer than prescribed without checking with your doctor.
- Some patients taking Belsomra have performed certain activities while they were not fully awake. These have included sleep-driving, making and eating food, making phone calls, and having sex. Patients often do not remember these events after they happen. Such an event may be more likely to occur if you use a high dose of Belsomra. It may also be more likely if you drink alcohol or take other medicines that may cause drowsiness while you use Belsomra. Tell your doctor right away if such an event happens to you.
- Muscle weakness can happen with Belsomra. This can last seconds to a few minutes and can happen both at night and during the day. Call your doctor right away if you have leg weakness while taking Belsomra.
- If you are overweight or are a woman, use Belsomra with care. The risk of Belsomras side effects may be increased. Discuss any questions or concerns with your doctor.
- PREGNANCY and BREAST-FEEDING: If you think you may be pregnant, contact your doctor. You will need to discuss the benefits and risks of using Belsomra while you are pregnant. Belsomra may cause prolonged sleep or severe breathing problems in the newborn if you take it during the last weeks of pregnancy, especially if you take it with certain medicines. Belsomra is found in breast milk. If you are or will be breast-feeding while you use Belsomra, check with your doctor. Discuss any possible risks to your baby.
When sleep medicines are used every night for more than a few weeks, they may lose their effectiveness to help you sleep. This is known as TOLERANCE. Sleep medicines should usually be used only for short periods of time, such as a few days and generally no longer than 1 or 2 weeks. If your sleep problems continue, contact your doctor.
When used for longer than a few weeks or at high doses, some people develop a need to continue taking Belsomra. This is known as DEPENDENCE or addiction. Be sure to tell your doctor if you have been dependent on alcohol, prescription medicines, or street drugs in the past.
