The treatment offered for a UTI to people who are allergic to penicillin will depend on their history and nature of the reaction. It is recommended that they avoid all antibiotics belonging to the penicillin family. These include:
- Amoxicillin
- Ampicillin
- Flucloxicillin
- Co-amoxiclav
- Penicillin V (Phenoxymethylpenicllin)
- Penicillin G ( Benzylpenicillin)
- Piperacillin + Tazobactam (Tazocin)
- Temocillin
Furthermore, antibiotics belonging to the cephalosporin family should also be avoided. This class of antibiotics are closely related to penicillin. These antibiotics include:
- Cefalexin
- Cefuroxime
- Ceftriaxone
- Cefotaxime
- Ceftazidime
It is important that your doctor is aware of your allergy and also what happens when you take penicillin. This is very important when determining which antibiotics can be prescribed for you to treat your UTI without triggering an allergic reaction to penicillin.
For further information on penicillin allergy please refer to the patient support section, where you can find a patient support leaflet on this topic. We have lots support available for people who suffer with antibiotic resistant UTIs too.
