How Long Before Sulfamethoxazole Works?

Updated

I got bitten by a spider and the hospital gave me Sulfamethoxazole to take for 7 days. How long will it be before the redness goes away so I can go back to work? The red spot is about the size of a quarter. Thank you.

Hello, Carmel! How are you?

The general rule with antibiotics is that if they are working you shouldn't see any worsening after taking them for a full 24 hours and you should start to see improvement after taking them for a full 3 days.

The FDA lists the typical side effects as possibly including nausea, dizziness, headache, non-allergic skin rash, and diarrhea.

Is there anything else I can help with?
