How Capagyl F Syrup works

Capagyl F Syrup is a combination of three medicines: Furazolidone, Metronidazole and Simethicone. Furazolidone is an antibiotic. It kills bacteria that cause diarrhoea by preventing them from forming the bacterial protective covering. Metronidazole is also an antibiotic which kills other infectious microorganisms in addition to bacteria by damaging their DNA. Together, they treat your infection effectively. Simethicone is an antifoaming medicine which disintegrates gas bubbles and allows easy passage of gas.

Frequently asked questions

What is Capagyl F Syrup used for?

Capagyl F Syrup is used to treat infectious diarrhea, dysentery, and other stomach and intestinal infections caused by bacteria or protozoa. It also provides relief from gas, bloating, and abdominal discomfort that often accompany these infections.

I have diarrhea with a lot of gas and cramping. Is Capagyl F Syrup a good option for me?

Yes, Capagyl F Syrup is specifically formulated for situations like yours. While the antibiotics treat the underlying infection that is causing the diarrhea, the simethicone provides targeted relief from the gas and bloating, making you feel more comfortable while the antibiotics do their work.

How quickly will I feel better after starting Capagyl F Syrup?

While individual results can vary, you may start to notice a reduction in diarrhea and bloating within a day or two of starting Capagyl F Syrup treatment. However, it is very important to complete the full course of medicine as prescribed by your doctor to ensure the infection is completely cleared, even if you feel better sooner.

I have heard some antibiotics can leave a bad taste in your mouth. Does Capagyl F Syrup also cause the same?

Yes, it is a common and harmless side effect of the metronidazole antibiotic present in Capagyl F Syrup to cause a temporary, unpleasant, metallic taste in your mouth. This taste should go away after you finish the full course of your oral medicine.

Are there any foods I need to avoid while taking Capagyl F Syrup?

Yes, because Capagyl F Syrup contains furazolidone, you must avoid eating foods that are high in tyramine. This includes aged cheeses, cured meats (like salami), fermented foods, soy sauce, and red wine. Eating these foods while taking this medicine can cause a sudden and dangerous increase in your blood pressure.

My urine has turned a brownish color after taking Capagyl F Syrup. Should I be concerned?

Brownish discoloration of urine is a normal and expected side effect. Both furazolidone and metronidazole can cause your urine to appear darker or reddish‑brown. This is harmless, and your urine color will return to normal after you stop taking the medicine.
