pizotifen
Summary
Pizotifen is used to prevent migraines and cluster headaches, which are severe headaches that occur in patterns or clusters. It helps reduce the frequency and severity of these headaches, making it easier for people to manage their symptoms over time.
Pizotifen works by blocking serotonin receptors, which are parts of the brain that respond to serotonin, a chemical that can cause blood vessels to narrow. By blocking these receptors, pizotifen helps keep blood vessels relaxed, reducing headache frequency and severity.
Pizotifen is usually taken once daily, often in the evening, to prevent migraines. The starting dose for adults is typically 0.5 mg to 1.5 mg per day, with a maximum of 3 mg daily. It can be taken with or without food, and the dose may be adjusted based on individual needs.
Common side effects of pizotifen include drowsiness, which means feeling sleepy, increased appetite, which can lead to weight gain, and sometimes stomach upset. These effects are usually mild and may decrease over time as the body adjusts to the medication.
Pizotifen can cause drowsiness, so avoid driving or operating machinery until you know how it affects you. It should not be used by people with narrow-angle glaucoma, which is increased eye pressure, or urinary retention, which is difficulty emptying the bladder. Always consult your doctor about your medical history before starting pizotifen.
