Rennie: uses, side effects & precautions

Indigestion is often caused by your stomach producing too much acid, which can irritate the lining of your stomach. Symptoms can include feeling bloated and full, belching, trapped gas, flatulence, feeling sick, pain and discomfort in your upper abdomen, and heartburn.

Symptoms usually occur after eating or drinking and can be more common at night (especially heartburn. Heartburn is the result of stomach acid traveling up your esophagus (food pipe). This effect is known as acid reflux. The acid irritates the lining of your esophagus, resulting in a burning feeling in your chest.

Rennie products contain antacids such as calcium carbonate and magnesium carbonate that work by neutralizing stomach acid.

You can take Rennie products to relieve indigestion or prevent it from occurring. To prevent indigestion, you should take the medication after meals and just before going to bed. How much you can take varies depending on the product. You should only take one Rennie product at a time. Also, it is best to avoid drinking alcohol because it can worsen your symptoms.

Note: Rennie products are only recommended for short-term use. You should speak to your doctor if you have ongoing symptoms of indigestion for more than two weeks.

As always, do not take the medication if you are allergic to any of the ingredients in it. If your doctor has recommended that you follow a low-calcium diet, you should speak with your doctor or pharmacist before using any Rennie products. If you have diabetes, it is best to try a sugar-free Rennie product.

Rennie products can interact with other medications like certain antibiotics (called tetracyclines and quinolones). If you take any prescription, over-the-counter, or herbal medicines, you should ask your doctor or pharmacist whether it is safe for you to take a Rennie product. They may recommend you take your usual medications at a different time than the Rennie product.

Generally, Rennie products are unlikely to cause side effects. However, occasionally some people may experience some side effects such as feeling sick, being sick, stomach upset, and diarrhea. If any side effects become bothersome, you should speak with your doctor or pharmacist.
