What should you know about strep throat treatment antibiotics?

Strep throat is caused by streptococcal bacteria, while many sore throats come from viruses. A clinician may use your symptoms, throat examination, and a test when needed to guide the decision. Antibiotics do not shorten every sore throat and will not help a viral infection. When prescribed for bacterial strep throat, they can reduce the bacterial load and help lower the chance of passing the infection on. Tell the prescriber about medicine allergies, previous reactions, pregnancy, and conditions that affect your immune system or kidneys.

Take the medicine at the dose and times advised, following any instructions about food or other medicines. Do not save doses for later, share tablets, or use antibiotics prescribed for a different illness. If you miss a dose, check the label or ask a pharmacist what to do rather than doubling up. Continue the course as instructed unless a clinician tells you to stop. Seek advice for troublesome diarrhoea, vomiting, or a new rash; get emergency help for facial swelling, wheezing, or severe breathing difficulty. Fluids, rest, and appropriate pain relief can support recovery.

Contact the prescribing clinician if symptoms worsen, fever continues, swallowing becomes harder, or you are not beginning to improve as expected. Urgent care is needed for difficulty breathing, inability to swallow saliva, drooling, severe dehydration, confusion, or rapidly increasing swelling in the throat or neck. A new rash with fever also deserves prompt medical advice, especially after starting a medicine. Do not assume that persistent symptoms mean you need a stronger antibiotic; reassessment may identify another cause.

Ask what evidence supports antibiotic treatment, how to take each dose, which side effects need a call, whether your regular medicines are compatible, and when you can return to work, school, or close contact with others.
