Fasigyn 500mg and 300mg tablets are an antibiotic used as a treatment for various bacterial infections. Their properties include the ability to kill the parasites and bacteria, causing diseases in your stomach, brain, liver, heart, skin, lungs, and genitals.
1. What is Fasigyn 300mg, 500mg Used For?
Fasigyn 500mg and 300mg are used to prevent infections that may start during or after surgery, as well as infections of male and female reproductive organs. The class of antibiotics is nitroimidazoles.
It’s not effective against viruses causing cold or flu, so it’s not recommended to use it unless necessary to avoid resistant bacteria overgrowth. If your doctor prescribes this medicine for the treatment of anything other than the following diseases, it’s fine. But self-treatment isn’t recommended.
If it seems suspicious that a specialist has prescribed these pills, don’t hesitate to ask questions. There’s nothing wrong with being curious about what medication you’re taking. Also, keep in mind that this medicine is only available with a doctor’s prescription.
1.1 Infections of the skin, blood, chest, lung or genitals
Fasigyn has been reported effective in treatments of bacterial infections affecting skin, blood, lungs, and genitals. The causing bacteria are anaerobic, which means they don’t need oxygen to survive. That’s why their area of development and growth is vast.
Fasigyn is a common antibiotic choice for patients with a penicillin allergy.
1.2 Infection associated with stomach ulcers in combination with other drugs
