Can you take flucloxacillin for tonsillitis?

Yes.

Flucloxacillin is a narrow-spectrum antibiotic that is used to treat bacterial infections, such as tonsillitis, caused by susceptible bacteria. It is effective against a variety of bacteria, including Streptococcus pyogenes, which is the most common cause of tonsillitis.

Flucloxacillin is typically taken by mouth, and the dose will depend on the severity of the infection and the patient's age and weight. It is important to take flucloxacillin as directed by the doctor and to finish the entire course of treatment, even if the symptoms improve, in order to ensure that the infection is fully treated and to reduce the risk of the bacteria developing resistance to the antibiotic.
