Mimosa asked

I was prescribed Bactrim for a skin infection that I have. I have a little bit of a headache and wanted to take Tylenol. Is that safe?

The quick answer
  • Tylenol and Bactrim are safe to take together with no known drug interaction.
  • Most over-the-counter pain relievers including ibuprofen and naproxen are also safe to combine with Bactrim.
  • Tylenol can help reduce both pain and fever if you have a temperature.
A quick summary of Dr. Brian Staiger, PharmD's full answer below, condensed by AI from that answer only (not from any outside source). The pharmacist's answer is the source of record.

Answer

There is no known drug interaction between Tylenol (acetaminophen) and Bactrim (sulfamethoxazole; trimethoprim). They are considered safe to take together.

In fact, most pain relievers are safe to take with Bactrim. In addition to Tylenol, Bactrim is safe to combine with these other over-the-counter analgesics:

  • Advil/Motrin (ibuprofen)
  • Aleve (naproxen)

It is important to remember that in addition to being a pain reliever, Tylenol is also a fever reducer and can be helpful if you also have a temperature.
