Stopping antibiotics like Megaclox after just two days is incomplete treatment, which often causes the infection to return and can lead to drug resistance. Do not self-medicate or restart these medicines on your own. Throat pain can be viral (which doesn't need antibiotics) or bacterial, and requires a professional diagnosis. Please consult a doctor or ENT specialist to examine your throat and prescribe the correct therapy. For temporary relief, do warm salt-water gargles, drink warm fluids, and use OTC throat lozenges. Seek immediate medical attention if you experience difficulty swallowing or breathing.
