How It Works

The active ingredient, bismuth subsalicylate, works by forming a soothing, protective coating over the lining of the stomach and intestines. It also has mild antiseptic and anti-inflammatory properties, which help to calm irritation and reduce the activity of bacteria that can cause digestive upset.

Adults and children aged 16 and over: take 30 ml (two tablespoons) every 30 minutes to 1 hour as needed. Do not take more than 8 doses (240 ml) in 24 hours. Shake the bottle well before use and measure each dose carefully using the cup provided. Do not use for more than 2 days without seeking medical advice.

Pregnancy and Breastfeeding

Pepto-Bismol is not recommended during pregnancy, particularly in the third trimester, as salicylates may affect the developing baby.

Speak to your doctor or PillSorted pharmacist before use if you are pregnant, trying to conceive, or breastfeeding.
