Frequently Asked Questions

Ofloxacin ke aam side effects kya hain?

Common side effects: nausea, diarrhoea, headache, dizziness, insomnia, rash, photosensitivity. These are usually mild. However, if tendon pain or tingling/burning in hands or feet occurs, STOP immediately.

Ofloxacin se tendon kyun toot sakta hai?

Fluoroquinolones affect collagen in tendon tissue — the Achilles tendon (at the heel) is at special risk. Risk is much higher in patients aged 60+, with renal failure, or taking steroids. Stop ofloxacin immediately if tendon pain occurs and see a doctor — tendon rupture can cause serious permanent damage.

Peripheral neuropathy kya hai aur kyun serious hai?

Ofloxacin can damage nerves in the hands or feet — causing tingling, burning, numbness, or weakness. This can be IRREVERSIBLE — meaning it may not resolve even after stopping the medicine. Stop immediately at the first sign and see a doctor.

Ofloxacin se photosensitivity kyun hoti hai?

Fluoroquinolones make the skin more sensitive to sun damage. Apply sunscreen and wear a hat or covered clothing when going out in direct sunlight during treatment.

Ofloxacin se diarrhoea ke baad C. difficile ho sakta hai?

Yes — any antibiotic, especially broad-spectrum, can disrupt gut bacteria and increase the risk of C. difficile infection. If severe watery or bloody diarrhoea occurs after the antibiotic course, see a doctor.
