Eosinophilia usually happens due to allergies, asthma, infections, or irritants. The best approach is to identify and avoid the trigger, treat any allergy or infection, and take medicines like antihistamines or doctor-prescribed anti-allergy tablets if needed. If your symptoms are frequent, severe, or your eosinophil count stays high, get a check-up so a doctor can find the exact cause and give the right treatment.

If you have swelling in your feet for three months, do not take Hetrazan on your own. Hetrazan is used only when swelling is caused by filaria infection, and that needs a proper diagnosis. It is better to get a simple checkup first to find the cause, and then take the right treatment safely.

If your doctor has diagnosed orchitis and prescribed Hetrazan and Zerodol-SP, it is usually safe to follow their treatment plan. Hetrazan helps if the cause is suspected to be due to a parasitic infection, and Zerodol-SP reduces pain and swelling. Take the medicines exactly as advised, rest well, use scrotal support, and apply cold packs if needed. If pain increases, swelling worsens, or you develop fever or difficulty urinating, get re-checked immediately.

Hetrazan 100 mg is commonly prescribed when testicle swelling is suspected to be due to a filarial infection or inflammation related to it. If your doctor has examined you and advised Hetrazan, it is generally appropriate. For a medical fitness test, temporary swelling due to infection is usually not a major issue once treated, but you should complete the full course of medicines and let the swelling settle before the test.
