Activis is an antacid medicine used to treat heartburn, acid reflux, bloating and gas, or upset stomach caused by eating or drinking too much. Activis is listed as an international medication from India that contains aluminum hydroxide, magnesium hydroxide, and simethicone. In the US, these ingredients are also found in Mylanta, Gelusil, and other over-the-counter (OTC) products.

Antacids work by raising the stomach pH to help neutralize acid.

  • Aluminum is a naturally occurring mineral. Aluminum hydroxide is used as an antacid.
  • Magnesium is also a naturally occurring mineral also used as an antacid. When not combined with aluminum, it can be used as a laxative to relieve constipation. It does this by increasing water in the intestines to induce a bowel movement. Magnesium can cause diarrhea and aluminum can cause constipation.
  • Simethicone is an antigas (antiflatulent) agent. It helps to relieve painful pressure caused by excess gas in the stomach and intestines.

Is Activis available in the US?

No, the brand name product Activis is not available in the US. Similar medicines containing aluminum hydroxide, magnesium hydroxide, and simethicone can be found over-the-counter (OTC) in American pharmacies. These can be purchased without a prescription from the pharmacy, grocery or other retail shops. Liquid antacids usually work faster than oral tablets, capsules, or chewable tablets.

Store brands or generics are also available to help lower cost. Ask your pharmacist if you need help finding an equivalent product for your symptoms.
