Butylscopolamine (Buscopan): What it is and when to use it

Got sudden stomach cramps or painful spasms? Butylscopolamine (often sold as Buscopan) is an antispasmodic medicine used to ease smooth muscle cramps in the gut, biliary tract, or urinary system. It doesn’t treat the cause of the pain, but it can provide fast symptom relief so you can get on with your day.

How it works and common uses

Butylscopolamine blocks certain nerve signals that make muscles contract. That relaxes spasms in the intestines, bladder, or bile ducts. Doctors commonly prescribe it for crampy abdominal pain, irritable bowel syndrome flare-ups, and sometimes for painful kidney or gallstones while waiting for other tests or treatment.

It’s available as tablets and injections. The injectable form is often used in emergency or hospital settings when quick relief is needed. Tablets are more common for short-term outpatient use.

Dosage, side effects, and warnings

Typical tablet dosing is 10 mg taken up to three or four times a day, depending on the product and country guidelines. Injectables are usually given as a single 20 mg dose by a healthcare professional and can be repeated if needed. Always follow the exact dose your doctor or pharmacist gives you—doses vary by brand and region.

Common side effects include dry mouth, blurred vision, constipation, and a faster heartbeat. Most are mild and go away after stopping the drug. Watch for red flags: trouble peeing, severe stomach pain that gets worse, very fast heart rate, or signs of an allergic reaction (hives, swelling, breathing trouble). If any of these happen, get medical help right away.

Certain people should avoid butylscopolamine or use it only with medical advice: those with glaucoma, enlarged prostate or urinary retention, myasthenia gravis, severe heart disease, or unstable blood pressure. Pregnant or breastfeeding people should check with their doctor before taking it.

Drug interactions matter. Combining butylscopolamine with other anticholinergic medicines (some antihistamines, antipsychotics, or bladder meds) can increase side effects. Tell your provider about all medicines and supplements you take.

Thinking of buying butylscopolamine online? Here’s how to do it safely: only use pharmacies that ask for a prescription when required, show clear contact details, and display accreditation or verified reviews. Avoid sites that sell prescription drugs without asking for a prescription or that offer suspiciously low prices. When in doubt, call the pharmacy and ask to speak to a pharmacist.

Store tablets in a cool, dry place and keep injectables as your provider instructs. Dispose of leftover medicine safely—don’t flush or toss in household trash unless local guidance says it’s okay.
