Antiflatulent (anti-gas medication)
Last reviewed June 2026
Who is this for?
Simeticone (also called simethicone) is a drug that breaks up gas bubbles in your stomach and intestines, making it easier for your body to release the gas naturally through belching or passing wind.
Reduces surface tension of gas bubbles in the gastrointestinal tract, promoting coalescence of small gas pockets into larger bubbles that are more easily expelled or absorbed through the intestinal mucosa.

Adults should take 40mg to 125mg after meals and at bedtime, up to 4 times a day. Chewable tablets should be chewed well before swallowing. Softgel capsules like Gazgo Softgel Capsules should be swallowed whole with water. You can take it with or without food, but it works best when taken after meals.
If you miss a dose, simply take it when you remember. If it is almost time for your next dose, skip the missed one. Simeticone works on the spot to relieve gas, so missing a dose is not dangerous — just take it when you feel bloated or gassy.
Buy from a reputable pharmacy — products like Gazgo Softgel Capsules should come in proper packaging with NAFDAC number, so avoid buying from roadside sellers or open markets. If your bloating or gas does not improve after a few days, see a doctor as it could be a sign of something more serious. Do not use it as a replacement for proper treatment of stomach ulcer or other digestive conditions.
Simeticone has very few drug interactions since it is not absorbed into the body. However, it may slightly reduce the absorption of thyroid medications like levothyroxine — take them at least 2 hours apart. It is safe to use with most other common medications including paracetamol and antacids.

Is it safe to take Simeticone with your other drugs?
Simeticone is generally considered safe during pregnancy and breastfeeding because it is not absorbed into the bloodstream, but it is still best to consult your doctor or pharmacist before using it.
Store in a cool, dry place away from direct sunlight and heat — Nigerian weather can be very hot, so avoid leaving it in your car or near a window. Keep the container tightly closed to protect from humidity. Always keep out of the reach of children.
