What should I avoid while taking Imodium?


Use caution when driving, operating machinery, or performing other hazardous activities. Imodium may cause dizziness or drowsiness. If you experience dizziness or drowsiness, avoid these activities.

Yes, it has been known to cause tiredness and drowsiness.

The known side effects are : dry mouth, flatulence, abdominal cramp and colic. Also nausea, vomiting, headache, meteorism, abdominal pain, and in rare cases severe hypersensitivity reactions including anaphylactic shock and anaphylactoid reactions.

A number of the adverse events reported during the clinical investigations and post-marketing experience with loperamide are frequent symptoms of the underlying diarrheal syndrome (abdominal pain/discomfort, nausea, vomiting, dry mouth, tiredness, drowsiness, dizziness, constipation, and flatulence). These symptoms are often difficult to distinguish from undesirable drug effects.

damned if you do , damned if you don't.

Isn't Imodium for constipation?

man oh man.. drowsiness and Imodium doesn't sound like a good combination..

You very well could wake up with an "October Surprise"

LMMFAO

I thought it was for the shits?

Why would you want to stop that and keep the toxins in? Shits are good for you. Get it all out, drink a Gatorade and shut up.

Don't forget the water!
