Sulfamethoxazole and drinking water

I was prescribed Sulfameth for a UTI only yesterday. I've taken three doses and I feel like complete and utter crap. I feel like I have a huge lump in my throat that goes down to my chest. It's very painful, like someone is standing on top of me. And it gets worse every time I swallow. Even drinking water makes it worse. At first I thought that huge pill just got stuck in my throat but it's been eight hours since I took it and it's still there. Last night I felt the same but I just thought that was from the infection. This morning I woke up feeling great but after taking it with breakfast it's all been downhill. Now my heartbeat is up, I'm getting dizzy and my hands feel really weak and shaky. I just called my doctor and they're switching me to something else. I just hope it makes me feel better than this stuff.

I had to stop 8 days into my 10 day prescription. Very hot, headache - woke up with hives and then discovered my entire body was red with a rash like sunburn. Turned itchy on my chest and arms. Face swelled a bit and looked sunburned also. Was happy to stop the medication early. Starting live yogurt to clear my system, eating garlic and drinking water.

The doctor at the university gave me this for my sinus infection. Thank God it was only a five day prescription. I'm on the last day as we speak. I ran into this site while searching for side effects. My symptoms have not been as severe as others. Headache, fatigue, stomach ache, and an uncontrollable appetite. I'm drinking water but not that much. Only around 40-60 ounces a day which is obviously not enough. I've been staying up very late at night. Bedtime is around 4-5 in the morning. Last night I noticed redness on my gums. When I brushed my teeth and used mouthwash it burnt like all hell. My gums feel better today. It hasn't been fun but I will say the medicine did its job. I don't feel the "rock" in my throat anymore thats for sure. Which is well worth the price concerning the side effects.

just got back from the ER...Sulfameth for 3 days now...totals 6 pills...can't sleep, nervous, dry mouth/white coated tongue, muscle cramps, nausea, general sick feeling...also was taking Buspar (anxiety) and Aciphex (heartburn), and also Reglan (anti-nausea)...made a major mistake by downing some sleeping pills (Walmart brand and a Nytol)...haven't slept more than 15 minutes in 3 days...right now, I'm "clean" for almost 24 hours...smoked a cigarette, having a beer and calling it a day (or three)...I'd recommend you SERIOUSLY talk to your doc about alternatives to this one...hadn't had any problems before taking it...already feeling better...have been drinking water all day to flush this stuff out...
