What is Belsomra

Belsomra is an FDA-approved prescription medicine for insomnia recommended for adults. It is prescribed to those who have trouble falling and remaining asleep for an entire night.

Belsomra is a controlled substance (Schedule IV) since it is prone to misuse and can cause an addiction. It relates to the class of dual orexin receptor antagonists (DORAs) and contains suvorexant, which is also Belsomra’s generic name.

How Does Belsomra Work

Belsomra stops orexin activity in the brain; orexin is the brain chemical that keeps the brain awake and alert. When the chemical’s activities are halted, the brain does not get a message to wake up, hence helping asleep.

Suvorexant takes effect with the first dose and has a half-life of 12 hours. The half-life can be longer in a person 65 years old and above, a patient with other medical conditions, or those using other medication. The drug remains in the body for two to three days before elimination from the system.

Consult a doctor to know if Belsomra is the best choice for insomnia treatment for you.

Belsomra (Suvorexant) Dosage

Belsomra is available as an oral tablet of four strengths: 5 mg, 10 mg, 15 mg, and 20 mg. The doctor initially prescribes a low dosage that is increased gradually to get to a patient’s appropriate amount. The standard daily dose is 10 mg, while the maximum dose is 20 mg daily. It also depends on a patient’s age, the severity of the sleep disorder, other medical conditions, and response to treatment.

Belsomra is administered once daily, at least thirty minutes before bedtime. A person should take sleep medicine if he/she has time to sleep for at least seven hours and always follow the doctor’s instructions.
