What to expect from antibiotic treatment for strep throat

Strep throat is an infection caused by streptococcal bacteria. A clinician may use a throat examination and testing to decide whether antibiotics are appropriate, because many sore throats have another cause. The medicine reduces the bacterial load and may lower the risk of spreading infection or developing complications, but it does not numb the throat immediately.

Warm drinks, cool foods, rest, and a suitable pain reliever can make swallowing easier. Do not give medicines intended for adults to a child without checking the label or a healthcare professional.

Take the antibiotic for the full prescribed course and use the measuring device supplied for liquid medicine. Keep hydrated with small, frequent sips if swallowing hurts. Avoid sharing cups, utensils, or toothbrushes while you are unwell, and wash your hands regularly. Ask when it is appropriate to return to school or work, particularly if fever continues or swallowing remains difficult.

Seek urgent care for trouble breathing, inability to swallow saliva, drooling, a muffled voice, severe one-sided throat pain, or difficulty opening the mouth. Contact a clinician promptly if dehydration develops, the fever is worsening, or a widespread rash appears. Lip, tongue, or throat swelling after a dose can signal a serious allergy and needs emergency help.

Was strep confirmed by a test? When should swallowing and fever start to improve? What should I do if I vomit a dose, and when am I no longer likely to pass the infection to others?
