Sore throat, fever and cough. Or 1gm?

From 2 days, I have had a sore throat which feels like my throat is burnt because of acidity. Hardly a month ago i visited an ENT doctor for cough which was treated after medication. Today i am having a fever of 99.2 F and cough. I had previously asked a question for treatment for my sore throat. Some kind doctors on Practo recommended that i take Amoxicillin/Amoxiclav, betadine gargle, antacid and antihistamines. But i do not know what dose of Amoxicillin to take. A month ago, i took Tablet Augpen ( Amoxicillin 250mg, Potassium clavunate125mg) for one course and followed up with Clarithromycin 500mg for another course after a week. (I have attached my prescription and throat image). Should i take 250mg Amoxicillin again or increase it to 500mg or 1gm? Thank you so much in advance!
