If your cold, cough, and fever have not improved after 3 days, it is important to continue your prescribed medicines and avoid changing them on your own. Augmentin 500 is an antibiotic, while Fexolife-M helps with allergy symptoms, Salbid LS Syrup relieves cough, and Ibugesic Plus helps reduce fever and pain. These medicines do have generic versions with the same ingredients that are usually more affordable, but any switch should be done only after consulting your doctor or pharmacist to ensure the correct dose and combination. Also, viral infections can take 4-5 days to improve, so supportive care like rest, fluids, and steam inhalation is important. If your fever persists beyond 4-5 days, worsens, or you develop breathing difficulty, it is important to revisit your doctor for further evaluation.
