Antibiotics Home > Vantin Warnings and Precautions
For some people, Vantin may increase the risk for serious complications, such as bloody diarrhea or yeast infections. Other precautions for using Vantin safely include warnings for potential drug interactions and possible dangers for women who are pregnant or breastfeeding. Also, people who are allergic to penicillin may also be allergic to this drug.
What Should I Tell My Healthcare Provider?
- Kidney disease, such as kidney failure (renal failure)
- Liver disease, such as hepatitis, cirrhosis, or liver failure
- An allergy to cephalosporin or penicillin antibiotics
- Any other allergies, including to foods, dyes, or preservatives.
- Pregnant or thinking of becoming pregnant
- Vantin contains an antibiotic that belongs to the cephalosporin group of antibiotics, which are related to penicillin antibiotics. Some people who are allergic to penicillin will also be allergic to Vantin. An allergic reaction can be quite dangerous. Let your healthcare provider know immediately if you notice any signs of an allergic reaction, such as:
- A rash
- Swelling of the mouth or lips
- Difficulty breathing.
- Make sure your healthcare provider knows if you have kidney disease, as the kidneys remove Vantin from the body. If your kidneys are not functioning well, you will need a lower and/or less frequent dosage.
- Let your healthcare provider know if you experience bloody or watery diarrhea. While diarrhea is a common side effect of Vantin, bloody or watery diarrhea may be a sign of a serious reaction that can occur when certain bacteria (Clostridium difficile) overgrow in the colon. This severe reaction can occur long after you stop using the drug and can be life-threatening.
- Antibiotics, including Vantin, can sometimes cause yeast infections, as they can get rid of "good" bacteria that help protect against yeast infections. Let your healthcare provider know if you develop a vaginal yeast infection or thrush (a yeast infection of the mouth) during treatment.
- Vantin should not be used to treat viruses, such as the common cold or the flu. This drug is completely ineffective for treating viruses, and such use can lead to bacterial resistance.
- Vantin may react with a number of other medications (see Vantin Drug Interactions).
- Vantin is a pregnancy Category B medication. This means that it is probably safe for use during pregnancy, although the full risks are currently unknown. Talk to your healthcare provider about the risks and benefits of using the drug when pregnant (see Vantin and Pregnancy for more information).
- Vantin passes through breast milk. Therefore, if you are breastfeeding or plan to start, talk with your healthcare provider prior to taking this drug (see Vantin and Breastfeeding for more information).
