1. When should I take an antacid vs. a Famotidine(Pepcid-AC) or Omeprazole (Prilosec)-like product?
Let's start with the basics. Antacids neutralize excess stomach acid to relieve heartburn, sour stomach, acid indigestion, and stomach upset. They are sometimes prescribed to help relieve the pain of stomach and duodenal ulcers. Some antacids also contain simethicone, an ingredient that helps eliminate excess gas.
You should take antacids exactly as directed by your doctor, or according to the manufacturer's directions. For stomach or duodenal ulcers, take the medicine for as long as your doctor tells you. If you are using the tablets, chew them well before swallowing for faster relief.
If you take any prescription or over-the-counter medications, you may have side effects. And one of them can be heartburn -- that burning in your chest or throat that happens when acid flows up from your stomach.
Don’t assume you’ll just have to live with it.
Make a list of all the medications you take, and ask your doctor if one of them may be causing your heartburn. Your doctor can change your medication, says Walter Coyle, MD, at Scripps Clinic Torrey Pines in California.
Products like Pepcid-AC are called histamine-2 blockers or H2 blockers. These drugs reduce production of stomach acid. Pepcid AC and other H2 blockers such as Tagamet HB, Zantac 75, and Axid AR are available in prescription-strength or in lower doses in over-the-counter varieties. These products are for relief of heartburn, acid indigestion, sour stomach, and other conditions, such as stomach ulcers.
The newest type of heartburn medication to become available without a prescription is Prilosec. Prilosec belongs to a family of drugs called proton pump inhibitors or PPIs. This type of drug is often used when antacids or H2 blockers fail. PPIs block the secretion of acid from the stomach. Prevacid and Nexium 24HR can be bought over the counter. Protonix, Aciphex, Dexilant, and Nexium are examples of other PPIs that are available only by prescription.
Antacids work the quickest to relieve occasional heartburn. For patients who do not respond to antacids, H2 blockers and PPIs are alternatives. Remember, though, that frequent or severe episodes of reflux should always be discussed with your doctor.
