Antacids are available without a prescription in liquid, chewable
tablet, chewing gum, and dissolving tablet forms to be taken by mouth.
Antacids—aluminum hydroxide, calcium carbonate, and magnesium hydroxide or magnesium carbonate—make stomach juices less acidic. Simethicone may help relieve gas symptoms.
Because acid reducers (H2 blockers and PPIs) do
not start to work right away, antacids may be used to relieve ulcer
symptoms during the first few days after a person begins taking an acid
reducer. The antacid may be used until the acid reducer is able to control the
Antacids do not work as well as H2 blockers and PPIs to help ulcers
heal. But they can help with ulcer symptoms, and in some cases they may help
small ulcers heal.
All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.

Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
If you are pregnant, breast-feeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.
Women who are pregnant may also be told to avoid antacids that contain sodium. Those antacids can cause extra swelling.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
