alcohol after taking sulfamethoxazole tmp

I have been taking sulfamethoxazole 2 times per day for 10 days. Today is the 10th day (my last dose). Can I drink alcohol tomorrow after 24 hours has passed? ## Hello, Michelle! How are you? That should be fine, as long as your doctor approves. However, you should be aware that it could still worsen some of the side effects, so you may feel more drowsy, dizzy and nauseous than usual, as listed by the FDA. One drink may affect you as if you'd had 2 and etc. Is there anything else I can help with?

sulfamethoxazole trimethoprim dosage
Post a Reply
I have the 800mg/160mg pills and want to cut them up to give to a dog with a UTI but I am unsure which mg dose I use to figure out how much to give to a 10# dog. Other web sites say 13mg per lb every 24hrs for dogs which would be 130mg a day, is that based on the 800mg of Sulfa. or the 160mg of the Trip?

I forgot that I left my bottle of the liquid Sulfamethoxazole out and it's been sitting in room temperature for over a week. Is it still good or no? ## Hello, Katie! How are you?

I was visiting my sister in PA and developed a bad urinary tract infection. I went to an Urgent Care walk-in. After getting the results of the culture, the doctor put me on sulfamethoxazole tmp ds. I took 2 and noticed that my face and neck was flushed. I had an appointment with my doctor in NJ when I got home, so I told her what I was given and about the flushing. She contacted the walk-in and got the results of the culture and told me to stop taking the sulfa drug and take the amox. After reading about each drug, it sounds to me as though the sulfa drug is better for a UTI. After taking the 2 sulfa pills, I felt like I had no symptoms at all but after 2 of the amox, I have some slight symptoms. Is one better than the other for a UTI? ## Hello, Jean! How are you?
