Infections caused by bacteria and parasites can become serious if left untreated. Powerful antibiotics like Flagyl are often needed to treat such infections, providing relief from symptoms and preventing the infection spreading or complications arising. This comprehensive guide explores everything you need to know if your doctor prescribes Flagyl.

What is Flagyl and How Does it Work?

Flagyl (generic name metronidazole) is an antibiotic and antiprotozoal medication. It belongs to the nitroimidazole class of antimicrobial drugs. Flagyl works by disrupting the DNA of bacteria and parasites, effectively killing them or stopping them from growing and spreading infection.

Uses of Flagyl for Treating Different Infections

Flagyl is used to treat bacterial vaginosis, vaginal infections, stomach ulcers caused by H. pylori, skin infections, bone and joint infections, pelvic infections, strep throat, lung abscess and more. It also treats parasitic infections like trichomoniasis, amoebiasis, giardiasis. Due to its broad activity, Flagyl is a first-line antibiotic for many stubborn infections.

Flagyl Dosage Information

Flagyl is available as 250mg and 500mg tablets, taken 1-3 times daily depending on condition severity. A common dosage is 500mg twice a day for 7 days. Flagyl comes as vaginal gels, creams and suppositories for treating vaginal infections as well. Always take Flagyl according to your doctor’s instructions. Complete the full course even as you feel better to fully eliminate the infection.

Flagyl Side Effects

Common side effects of Flagyl include nausea, metallic taste, vomiting, stomach cramps, headache and yeast infections. More serious but rare side effects may include seizures, nerve damage and liver damage. Discontinue Flagyl and seek emergency care if any severe side effects occur. Always discuss any side effects with your prescribing physician promptly.

Important Flagyl Warnings and Safety Information

Do not drink any alcohol while taking Flagyl and for at least 3 days afterwards, as this may cause severe nausea, vomiting, cramps, flushing, headache and rapid heart rate. Women should use backup contraception while on Flagyl, as it may make birth control pills less effective. Flagyl makes skin more sensitive to UV light, so limit sun exposure. Let your doctor know if you have any liver or kidney problems before starting Flagyl.

Using Flagyl to Treat Infections in Dogs

Veterinarians often prescribe Flagyl to treat bacterial and parasitic infections in dogs, like diarrhea, bloody diarrhea, inflammatory bowel disease, giardiasis and more. Dosages range from 5-50mg per pound given twice daily. Only give your dog Flagyl under the direction of a vet. Monitor for side effects like vomiting, diarrhea or neurologic problems and report these promptly.

Accessing Generic Metronidazole to Reduce Costs

Since the patent for Flagyl expired decades ago, many pharmacies offer generic metronidazole at a much lower price point compared to the brand name. Studies confirm generic metronidazole works equally well for clearing infections. Discuss filling your Flagyl prescription with generic metronidazole with your pharmacist or doctor to reduce your medication costs.

Flagyl Fights Infections and Parasites

When used as directed, Flagyl is an effective antibiotic treatment for numerous bacterial and parasitic infections. Take it exactly as prescribed and complete the entire course of treatment. Be aware of potential side effects and drug interactions. Avoid alcohol completely while on Flagyl. The generic form provides a less expensive alternative.
