When and How to Use It

Some general considerations to keep in mind during treatment with Rifadin include the following:
  • Rifadin comes as a capsule or an injection. The capsule is normally taken by mouth once or twice a day. The injection is normally given through a needle inserted into a vein (an intravenous, or IV, injection).
  • You should take Rifadin capsules on an empty stomach, with a full glass of water, one hour before or two hours after a meal.
  • The medication can be made into a liquid suspension for people who have difficulty swallowing the capsules, such as children. Ask your healthcare provider or pharmacist if you are interested in this option.
  • Rifadin liquid suspension must be shaken well before use.
  • For the medication to work properly, it must be used as prescribed. Missing doses or not completing the full course of treatment will increase the chance that your infection will not resolve and that the bacteria causing your infection will become resistant to Rifadin or other antibiotics.

Dosing Information

The dose of Rifadin your healthcare provider recommends will vary, depending on several factors, including:
  • Your weight
  • The reason you are using it
  • How you respond to it.
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.

Side Effects of Rifadin

Just like any medicine, Rifadin can cause side effects. However, not everyone who uses the drug will experience problems. Most people tolerate it quite well.
If reactions do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider. Serious side effects are less common.
Some of the possible Rifadin side effects include but are not limited to:
  • Heartburn
  • Loss of appetite
  • Headache
  • Drowsiness
  • A reddish color of the urine, sweat, saliva, and tears.
