Donnatal (belladonna alkaloids, phenobarbital) is used to treat abdominal pain, bloating and cramps in patients with irritable bowel syndrome. It is also used to treat acute inflammation of the stomach and intestines (gastroenteritis) to reduce pain and diarrhea, and in patients with duodenal ulcer. Donnatal contains belladonna alkaloids (hyoscyamine, atropine, and scopolamine) that belong to the anticholinergic/antispasmodic class of drugs, and phenobarbital that belongs to the barbiturate sedatives class of drugs. This medication is available in generic form. Common side effects include dizziness, drowsiness, weakness, blurred vision, dry eyes, dry mouth, nausea, constipation, and abdominal bloating.

The dosage of Donnatal is adjusted to individual patients for symptomatic control with minimum adverse reactions. The usual dose is one tablet every 8 or 12 hours as prescribed. Products that may interact with Donnatal include blood thinners, ketoconazole, MAO inhibitors, bronchodilators, bladder or urinary medications or irritable bowel medications. Hormonal birth control products (pills, patch, ring) may not be effective if taken with Donnatal. Discuss all medications you are taking with your doctor. Donnatal is not recommended for use during pregnancy. It may harm a fetus. Consult your doctor. This medication passes into breast milk and may have undesirable effects on a nursing infant. Consult your doctor before breast-feeding. Donnatal may cause withdrawal symptoms (anxiety, muscle twitching, shakiness, dizziness, worsening weakness, nausea, vomiting) if you suddenly stop using it. Withdrawal from phenobarbital can be severe and include seizures or death.
