Feeling better after four tablets does not mean the infection has cleared, and stopping early can lead to incomplete treatment and antibiotic resistance. Most amoxicillin clavulanic acid courses usually require 5 to 7 days of treatment, depending on the infection type, so you should not stop the medicine without your doctor’s approval. You should contact your doctor to confirm the correct total duration for your specific condition, as only they can determine the safe course length based on your diagnosis and recovery.
