Isometheptene

Isometheptene is a vasoconstrictor used to treat migraine and cluster headaches. It is often combined with other medications, such as paracetamol (acetaminophen) or chlorpheniramine, and is sold under various brand names.

Pharmacology

Isometheptene works by constricting blood vessels in the brain, which helps to alleviate the pain of migraines and cluster headaches. It is believed to act on the serotonin system, although the exact mechanism of action is not fully understood.

Uses

Isometheptene is primarily used to treat migraines and cluster headaches. It is often used in combination with other medications, such as paracetamol or chlorpheniramine, to increase its effectiveness.

Side Effects

Common side effects of isometheptene include nausea, vomiting, and dizziness. In rare cases, it can cause serious side effects such as hypertension (high blood pressure), tachycardia (rapid heart rate), and ischemia (reduced blood flow to the heart).
