What Should You Not Mix With Metronidazole?

Metronidazole, also known by the brand name Flagyl, is an antibiotic medication used to treat a variety of infections. It is commonly prescribed to treat bacterial infections, particularly those caused by anaerobes, which are types of bacteria that cannot survive in oxygen. Metronidazole is taken orally or intravenously, depending on the severity and type of infection being treated. As with any medication, it is important to be aware of what should not be mixed with metronidazole for safety reasons.

Do Not Mix With Alcohol

The primary precaution to take when taking metronidazole is to avoid consuming alcohol while taking the medication. This is because the combination of metronidazole and alcohol can cause serious side effects, such as vomiting, nausea, dizziness, flushing, headache, and palpitations. In some cases, these side effects can be so severe that they can be life-threatening.

It is important to note that consuming alcohol while taking metronidazole is not the same as drinking alcohol after the treatment has been completed. The side effects of taking metronidazole and drinking alcohol can occur up to 72 hours after completing the course of treatment.

Do Not Mix With Cimetidine

Another drug that should not be mixed with metronidazole is cimetidine. Cimetidine is a drug used to reduce stomach acid production and is sometimes given to people with heartburn or indigestion. Taking cimetidine and metronidazole together can increase the amount of metronidazole in the body and lead to a higher risk of side effects. For this reason, it is important to let your doctor know if you are taking cimetidine before starting treatment with metronidazole.

Do Not Mix With Warfarin

Warfarin, also known as Coumadin, is a blood thinner used to prevent blood clots. Taking warfarin and metronidazole together can result in an increased risk of bleeding, so it is important to let your doctor know if you are taking warfarin before starting treatment with metronidazole. Additionally, it is important to have regular blood tests to monitor warfarin levels while taking both medications.

Other Drugs To Avoid

In addition to avoiding alcohol, cimetidine, and warfarin, there are some other medications that should not be taken with metronidazole:

• Lithium
• Phenytoin
• Disulfiram
• Busulfan
• Carbamazepine

If you are taking any of these medications, it is important to let your doctor know before starting treatment with metronidazole. Your doctor may adjust your dose or recommend an alternative treatment for your infection.

Conclusion

Metronidazole is a useful antibiotic medication for treating bacterial infections, but it is important to be aware of what should not be mixed with it. Alcohol, cimetidine, warfarin, and certain other medications can interact with metronidazole and cause serious side effects. If you are taking any of these medications, make sure to tell your doctor before starting treatment with metronidazole.
