Does Tylenol 3 work for bladder infections?

No, unfortunately Tylenol does not work for bladder infections. Although there is pain involved, it doesn't really lessen the pain either. It would be best to get a prescription, if you don't have health care, you can look into planned parenthood, and receive treatment for free, they may also have options at your local free clinic.

It would be best to get treatment asap as the symptoms don't always lessen.

Take Care! :D
