Q-Pas Granules is an antibiotic medicine used to treat bacterial infections in your body. It is used to treat tuberculosis that is resistant to other medicines. It is generally used in combination with other medicines, as part of a regimen. Q-Pas Granules works by stopping the growth of the infection causing bacteria. It may be taken with or without food, preferably at a fixed time each day. You should take it regularly at evenly spaced intervals as per the schedule prescribed by your doctor. Taking it at the same time every day will help you to remember to take it. The dose will depend on what you are being treated for, but you should always complete a full course of this antibiotic as prescribed by your doctor. Do not stop taking it until you have finished, even when you feel better. If you stop taking it early, some bacteria may survive and the infection may come back. The most common side effects of this medicine include allergic reactions, skin rash, vomiting, and nausea. Seek emergency medical help if you get a rash, itchy skin, swelling of face and mouth, or have difficulty breathing. Before using it, you should tell your doctor if you are allergic to any antibiotics (especially sulpha medicines) or have any kidney or liver problems. Pregnant and breastfeeding mothers should not take this medicine. Your doctor may get regular blood and urine tests while undergoing treatment with this medicine.
