Methscopolamine bromide is a prescription medication that has been used for decades to help manage the symptoms of peptic ulcers. It belongs to a class of drugs called anticholinergics — agents that block certain nerve signals to reduce stomach acid and gut movement. If you've been prescribed methscopolamine or are researching it for the first time, here's everything you need to know.
What Is Methscopolamine?
Methscopolamine is the generic name for this medication. It's a quaternary ammonium derivative of scopolamine — meaning it's a chemically modified version of scopolamine that is designed to stay in the gut rather than crossing into the brain. This makes it more targeted for GI symptoms and less likely to cause the central nervous system side effects (like confusion or hallucinations) that scopolamine can produce.
The brand names Pamine and Pamine Forte have been discontinued, so only the generic version is currently available in the U.S. The full generic name is methscopolamine bromide.

What Is Methscopolamine Used For?
The FDA-approved indication for methscopolamine is:
Peptic ulcer disease (adjunctive therapy): Used alongside other treatments to reduce stomach acid and relieve pain from peptic ulcers. It is not a primary treatment and has not been shown to heal ulcers or prevent them from coming back.
Methscopolamine is also found as an ingredient in combination cold, allergy, and upper respiratory products (combined with antihistamines and decongestants) where it serves as a drying agent to reduce nasal secretions.
Off-label uses that doctors may prescribe it for include:
Irritable bowel syndrome (IBS)
Stomach and intestinal spasms
Reducing excessive salivation
How Is Methscopolamine Taken?
Methscopolamine comes in tablet form (2.5 mg and 5 mg). It is taken orally on an empty stomach, 30 minutes before meals and at bedtime. The timing before meals is important — the drug needs to be absorbed before eating in order to reduce acid secretion and slow digestion during the meal.
What Is the Typical Methscopolamine Dose?
The standard adult dosing for peptic ulcer (adjunctive therapy) is:
Starting dose: 2.5 mg taken 30 minutes before each of 3 meals, plus 2.5-5 mg at bedtime. Total: 12.5 mg per day.
For severe symptoms: 5 mg before each meal and at bedtime. Total: 20 mg per day.
Maximum: Some patients have tolerated up to 30 mg per day, but this is not typical.
Your doctor will adjust your dose based on how well you respond to treatment and any side effects you experience. Never adjust your dose on your own.
Who Should NOT Take Methscopolamine?
Methscopolamine is contraindicated (not safe) for people with:
Glaucoma
Enlarged prostate or bladder obstruction (obstructive uropathy)
Myasthenia gravis
Paralytic ileus or intestinal obstruction
Toxic megacolon or severe ulcerative colitis
Children under 18
Older adults (65+) should use methscopolamine with caution or avoid it entirely due to increased risk of anticholinergic side effects.
Is Methscopolamine a Controlled Substance?
No. Methscopolamine is not a controlled substance and is not scheduled by the DEA. This means it can be prescribed by any licensed provider, including via telehealth, and can be phoned in or e-prescribed to any pharmacy without special restrictions.

Is Methscopolamine the Same as Scopolamine?
No — they are related but different. Scopolamine (sold as Transderm Scop) is a patch used to prevent motion sickness and nausea. Methscopolamine is an oral tablet used for peptic ulcers. Methscopolamine is a chemically modified (methylated) form of scopolamine designed not to cross the blood-brain barrier. Do not use both medications together — combining two anticholinergic drugs significantly increases the risk of serious side effects.
Where Can I Find Methscopolamine in 2026?
Methscopolamine can be challenging to find since the brand Pamine has been discontinued and many pharmacies don't routinely stock the generic. Use medfinder to quickly locate pharmacies near you that have it in stock. For a full guide, see: How to Find Methscopolamine In Stock Near You.
Frequently Asked Questions
Methscopolamine bromide is FDA-approved as an adjunctive (add-on) therapy for peptic ulcer disease in adults. It works by blocking acetylcholine receptors in the gut to reduce stomach acid secretion and slow GI movement, helping relieve pain and discomfort. It is also used off-label for IBS, GI spasms, and to reduce excessive salivation. It is found as an ingredient in some combination cold and allergy medications.
The standard starting dose of methscopolamine for peptic ulcer is 2.5 mg taken orally 30 minutes before each of 3 meals, plus 2.5 to 5 mg at bedtime (12.5 mg total per day). For more severe symptoms, the dose may be increased to 5 mg before meals and 5 mg at bedtime (20 mg/day). The maximum tolerated dose in some patients is 30 mg/day. Your doctor will adjust the dose based on your response.
Yes. Pamine and Pamine Forte were brand-name versions of methscopolamine bromide — Pamine contained 2.5 mg tablets and Pamine Forte contained 5 mg tablets. Both brand products have been discontinued. Only the generic methscopolamine bromide tablets (2.5 mg and 5 mg) remain available. Ask your pharmacist for generic methscopolamine bromide if you were previously taking Pamine.
Methscopolamine is a chemically modified (quaternary ammonium) form of scopolamine that is designed to act primarily in the gastrointestinal tract and does not readily cross the blood-brain barrier. Scopolamine (Transderm Scop) is a transdermal patch used for motion sickness. Their routes of administration, indications, and side effect profiles differ significantly. Do not use both together — combining anticholinergic medications increases the risk of serious adverse effects.
