A 24-year-old member asked:

how effective and safe are pepto-bismol and tums (calcium carbonate)? how do they work?

Specializes in Colon and Rectal Surgery
Fairly safe: Both are reasonably safe for short term use. However, long term use can lead to problems. Both work primarily by coating the stomach to help acid effects. With prolonged use the normal bacteria in the GI tract can be depleted and abnormal bacteria can overgrow. Alos prolonged use of peptobismol can cause discoloration of the intestinal tract along with elevated levels of bismuth.

Instructions: Follow instructions for these products. Tums contain calcium and too much is dangerous. They provide only temporary relief of heartburn by neutralizing stomach acid. Pepto bismol contains bismuth which reduces diarrhea. It may turn your BM's blackish but has little other side effects. Follow directions!

Yes: Classic antacids, whether tablets (tums) or liquids (maalox) are certainly safe and sometimes a "life-saver" in the third trimester! however, don't hesitate to mention your symptoms to your ob; worsening heartburn or reflux can be treated or prevented with prescription antacids and ppis (proton pump inhibitors) like Omeprazole (prilosec).

Yes: Antacids like Tums are a good choice for heartburn in pregnancy. They neutralize the acid and are good when you have the symptoms. If you have to take them often though taking a preventative medicine daily will be helpful. Omeprazole, Prevacid and Zantac (ranitidine) are good choices. These prevent heartburn before you feel the symptoms.

Depends: We do not recommend calcium supplementation for the heck of supplementing. We always prefer you to get your calcium from your food. However, in men who has osteoporosis or osteopenia, calcium supplementation + vitamin d is appropriate and recommended.

What happens if you take a calcium supplement before having a bone densitometry test?

2 doctor answers3 doctors weighed in
Dr. William Banks Hinshaw
Obstetrics and Gynecology 43 years experience
Avoid this: Bone mineral density tests measure the amount of mineral in the bone, and this mineral is predominantly calcium. The presence of calcium in your digestive tract may be detected and falsely interpreted as bone mineral, giving an inaccurate increased result.
