I had the Pfizer vaccine 3 days ago. I have also had cystitis for 2 days. Can I take an antibiotic treatment?

Hello,

There are no reported interactions between Pfizer's COVID-19 vaccine and antibiotics. Therefore, you can start treatment now without concern if you have an ongoing urinary tract infection. It is not recommended to delay treatment in this situation to avoid worsening the infection and spreading to the kidneys.

Do not hesitate to contact us if you have any other questions,
