How to use Rifampin

This medication is best taken on an empty stomach with a full glass of water (8 ounces or 240 milliliters) 1 hour before or 2 hours after meals; or take as directed by your doctor. If you have nausea, do not take antacids with rifampin since it will lessen the effectiveness of this drug. However, if you need to take antacids, wait at least 1 hour after taking this drug.

If you are unable to swallow the capsules, you may open the capsule and sprinkle the contents onto a spoonful of cool, soft applesauce or jelly. Eat the entire mixture right away. Do not prepare a supply for future use.

If you have a liquid form, shake the bottle well before each dose. Use a medication-measuring device to carefully measure the prescribed dose.

Rifampin is frequently used in combination with other antibiotics to prevent or treat certain kinds of infections (e.g., latent/active tuberculosis, meningococcal disease). Your dose/schedule/treatment length will vary, depending on what you are treated for. For the best effect, take this medication at evenly spaced times, or exactly as directed. To help you remember, take this medication at the same time(s) every day. Continue to take this medication until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may allow bacteria to continue to grow, which may result in a return of the infection.

Inform your doctor if your condition persists or worsens.
