Mecamylamine

Name: Mecamylamine

What is mecamylamine?

Mecamylamine is used to treat moderate to severe hypertension (high blood pressure). Because of its many side effects, mecamylamine is not commonly used.

Mecamylamine may also be used for purposes other than those listed in this medication guide.

What happens if I miss a dose?

Take the missed dose as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take only your next regularly scheduled dose. Do not take a double dose of this medication.

What other drugs will affect mecamylamine?

Generally, mecamylamine should not be used during treatment with antibiotics or sulfa-based drugs. Tell your doctor if you are taking drugs of either of these types.

Other drugs used to lower high blood pressure may increase the effects of mecamylamine, and serious side effects could occur. Tell your doctor about all medicines you take to lower high blood pressure or to treat other heart conditions.

Anesthesia (use of drugs that put you to sleep for surgery) may also increase the effects of mecamylamine. Tell your doctor or dentist that you are taking mecamylamine before you have surgery.

Drugs other than those listed here may also interact with mecamylamine or affect your condition. Talk to your doctor and pharmacist before taking any prescription or over-the-counter medicines.
