Imodium (loperamide) typically starts to work within about 1 hour after taking the dose, helping to slow down diarrhea. Its half-life, or the time it takes for the level of the drug in the body to reduce by half, is about 9 to 13 hours, averaging around 11 hours. This means it can remain active in the body for a relatively long time. Usually, it takes about 2 to 3 days for Imodium to be fully eliminated from the body. Most people only need to use Imodium for 1 to 2 days, and it is advised not to take it for longer than 48 hours without medical supervision. Key points:
- Imodium starts working within 1 hour.
- Half-life is approximately 9-13 hours (average 11 hours).
- Fully eliminated from the body in about 2-3 days.
- Typically used for up to 2 days unless directed by a doctor.
- Overuse or high doses can prolong its presence in the body and may cause serious side effects.
This information addresses how long Imodium lasts in the body and how long its effects last for controlling diarrhea.
