Since your symptoms, especially tonsillitis, have not improved after 5 days, Lupihist syrup alone is insufficient. Tonsillitis is often viral or bacterial and may require targeted anti-inflammatory medication or prescription antibiotics rather than just cough syrup. I highly recommend visiting a healthcare professional to have your throat examined. In the meantime, you should stop Lupihist. For relief, try warm saline gargles 3-4 times a day, stay well-hydrated, and you may take Paracetamol (500mg) to help ease throat pain and fever. Please avoid self-medicating with antibiotics without a doctor's physical evaluation.
