Your doctor has prescribed him accurately. And for the loose stool, please use oral rehydration solutions (JEEVAN JAL) too, sometimes Amoxicillin clavulanate has been found to cause diarrhea too, but, yet one of the symptoms of COVID-19 is diarrhea too, so its very difficult to differentiate between the two. . And if there is fever despite taking paracetamol three times a day, do consult to nearest hospital. Fever is one of the major symptom for COVID-19, and if this has been persistent even after consumptions of Paracetamol, it's time for use to see Some blood works too. Do perform 6 minute walk test and measure O2 saturation after that. For throat pain, it'll take some days to return back to normal. But the medications that you are being given shall work. You can add, ORAL GARGLE SOLUTIONS( BETADINE/ CHLORHEXIDINE/lukewarm water and salt) to relieve it too. Wishes for quick recovery of your relative.
