Imodium Plus – Loperamide hydrochloride, dimethicone uses, dose and side effects


2 mg /125 mg tablets
loperamide hydrochloride, dimethicone

1. What Imodium Plus is and what it is used for

The tablets contain two active substances:

  • Loperamide hydrochloride, which reduces diarrhea by normalizing excessive bowel movements and which also facilitates the absorption of water and salts from the intestine.
  • Dimethicone, which dissolves the gas bubbles in the gastrointestinal tract that cause stomach cramps and bloating.

Imodium Plus tablets are used in adults and adolescents over the age of 12, to treat temporary diarrhea when the diarrhea is associated with stomach cramps, bloating, and flatulence.

2. What you need to know before using Imodium Plus

Do not use Imodium Plus

  • to children under 12 years.
  • if you are allergic (hypersensitive) to loperamide hydrochloride, dimethicone or any of the other ingredients of the tablets (see section 6).
  • if you have a fever (above 38 ° C) or blood in your stools.
  • if you have a relapse of an inflammatory bowel disease such as ulcerative colitis .
  • if you have severe diarrhea after using antibiotics .
  • if you are constipated or if your stomach appears to be swollen.

Warnings and cautions

Talk to your doctor or pharmacist before taking Imodium Plus.

  • Imodium Plus only treats the symptoms of diarrhea. In some cases, the cause of your diarrhea may require treatment. If symptoms persist or worsen, consult your doctor. If you have severe diarrhea, your body loses more fluid, sugar and salts than normal. You need to compensate for the fluid loss by drinking more than you normally do. Ask the pharmacy staff about preparations that replace sugar and salts.
  • If you have AIDS and your stomach swells, stop taking the tablets immediately and contact a doctor.
  • If you have liver disease, you should consult your doctor before starting treatment with the tablets. Some of the side effects can be more troublesome.

Do not take this medicine for anything other than its intended use (see section 1) and never take more than the recommended dose (see section 3). Severe heart problems (with symptoms such as fast or irregular heartbeat) have been reported in patients who have taken too much loperamide, the active substance in Imodium Plus.

In case of temporary diarrhea, the symptoms usually stop within 2 days. If symptoms persist after that period, discontinue treatment and consult a physician.
