Generic Name: mecamylamine (mek-ah-MIL-a-meen)
Brand Name: Inversine
Inversine is used for:
Treating severe high blood pressure. It may also be used for other conditions as determined by your doctor.
Inversine is an antihypertensive agent. It works by relaxing and dilating (widening) blood vessels. Blood flows more freely and at a lower pressure through dilated blood vessels, which helps to lower blood pressure.
Do NOT use Inversine if:
- you are allergic to any ingredient in Inversine
- you have heart problems or have recently had a heart attack
- you are taking an antibiotic or sulfonamide (eg, sulfamethoxazole)
- you have glaucoma, certain complications from kidney disease (eg, increased levels of waste products in the blood), or narrowing of the passage from the stomach into the intestine (pyloric stenosis)
Contact your doctor or health care provider right away if any of these apply to you.
