Frequently asked questions

Does Buscopan make you sleepy?

Very little of it reaches the brain, so drowsiness is uncommon, unlike the travel-sickness form of hyoscine.

Is it the same as travel-sickness hyoscine?

No. Hyoscine hydrobromide is used for motion sickness; butylbromide acts mainly on the gut.

When should I see a doctor instead?

If pain is severe, keeps returning, or comes with fever, weight loss or bleeding, get it checked rather than relying on cramp relief.
