Sulfamethoxazole and diarrhea

I was prescribed this drug for a UTI. I've been on it for 6 days already (10 day treatment) and thankfully have not experienced the severe side effects that some people on this site have. I noticed that a few of the entries mentioned that people with penicillin allergies shouldn't be put on this. I'm surprised that my doctor put me on it in that case, but I haven't really had any allergic reactions to it.

However, I have had a few minor side effects. A couple days ago, I had a horrible headache. As for anxiety/depression, I was suffering from that anyway due to real life circumstances so it's impossible for me to tell whether or not the pill had any effect on it (I don't think so, because I feel fine now). As for ongoing side effects, I have actually felt extremely gassy lately, and I know it has nothing to do with my diet. The first day on this pill was fine, but after that I started experiencing this problem. I also had some diarrhea when I first started on it.

Well, I'm done with this pill in four more days. The good news is that it COMPLETELY cured my UTI and I definitely feel much better than I did when I was running to the bathroom every five minutes.

I was prescribed sulfameth for an infection from a possible bug bite. After three days of taking this drug, I've had a severe headache, nausea, diarrhea, chills, fever, excessive perspiration, tightness and pain in my chest, dizziness, tingling around my lips, low back pain, weird nightmares and fitful sleep. Also, my blood sugar level is significantly elevated and I have constant stiffness and soreness in my neck. I'm just now coming to this website after experiencing these side effects for a total of five of the eight days I've been on the sulfameth.

I am a 42 y/o woman rxed sulfameth far a UTI. I just completed my 5 day rx. From day one I had diarrhea, and stomach upset, but for the past 2 days I have heartburn which was rivaled only by the hearburn when at the end of my pregnancy with twins. It burns when I eat, and when I don't. I have gas, and the burps. And today I have begun to have joint pain in my jaw, throat, and in my chest if I take a deep breath. The strange thing is I have taken Bactrim in the past with no ill effects. Is the generic really that different...or am I just old! Hopefully the side effects will subside now that I have completed my course of meds. (it also made my chronic eczema worse...but just about anything can trigger that)

My Dr. instructed me to take the medication twice a day for 5 days. About 15 hours after I finished the medication (on the 5th day), I was extremely nauseous and had diarrhea for 13 hours, which towards the end was a bright yellow color. I lost 4 pounds in 13 hours! I will never take this medication again!

I was prescribed Sulfameth/Trimeth DS 800/160. I have to take the pill 2 times a day for 3 days for a UTI. After taking my first pill the burning went away, but I woke up in the middle of the night with horrible abdominal cramps, worse than the ones I would get with menstruation. I also had headaches, neck aches, diarrhea, nausea and a wicked loss of appetite. I can't believe after all of these negative side effects the drug is still prescribed! I would rather have the UTI than have to deal with Sulfa ever again
