Belladonna alkaloid combinations and phenobarbital are used to relieve cramping pains in conditions such as irritable bowel syndrome and spastic colon. They also are used with other medicine to treat ulcers. These medicines decrease the motion of the stomach and intestines and the secretion of stomach fluids, including acid.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Belladonna alkaloid combinations and phenobarbital come as a regular tablet, a slow-acting tablet, capsule, and liquid to take by mouth. The regular tablet, capsule, and elixir are usually taken three or four times a day, 30 minutes before meals and at bedtime. The slow-acting tablet usually is taken two or three times a day at evenly spaced intervals. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take belladonna alkaloid combinations and phenobarbital exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Phenobarbital can be habit forming. Do not take a larger dose, take it more often, or for a longer period than your doctor tells you to. Signs of overdose are headache, nausea, vomiting, dizziness, blurred vision, dilated pupils in the eye, hot and dry skin, dry mouth, agitation, and difficulty swallowing. If you have any of these symptoms, stop taking belladonna alkaloids and phenobarbital and call your doctor immediately.
