OK after 3 - 5 days: Mopst uncomplicated utis have cleared after 3 days on antibiotics, certainly by 5. So quite safe to stop. Macrodantin or Cipro (ciprofloxacin) xcould be prescribed in the future if you get another uti. Your 2nd dr. Has given sound advice if you are 3days+ on bactrim.

U need to see ur pcp: Bactrim (sulfamethoxazole and trimethoprim) and other sulfa drugs r notorious for making people sick. If it is just a drug reaction, u could try to tough it out. The problem is Bactrim (sulfamethoxazole and trimethoprim) is also known for severe allergic reactions so my patients c/o rash or itching I usually stop it right away and change it to something else if possible

Heat exhaustion: This is the stage before heat stroke.Stay cool, hydrate, and try not to overheat again. Once this happens, you become more sensitive to the heat. Bactrum can cause a sun sensitivity but this is usually in the form of a sunburn like rash.

Bactrim side-effect: Bactrim (TMP/SMX) can cause neurologic side effects - so I would place the blame there. It's extremely important though to notify your doctor - the one who prescribed those antibiotics. Hopefully your infection is well treated enough where you can stop everything. There are plenty of other agents that could be used to fight an infection like that. Stopping before things get worse is important.

Yes: Stop Bactrim (sulfamethoxazole and trimethoprim) immediately although this is may not be an allergic reaction in the absence of any skin involvement, The question is why was Bactrim (sulfamethoxazole and trimethoprim) given in the first place?

Side effect: You need to let the doctor that prescribed this medication know what is going on and see if they need to change your antibiotic. Bactrim (sulfamethoxazole and trimethoprim) is a sulfa drug and some people have this reaction to it. Do not take more and call your prescriber.

Here are some...: Have you noticed your urinary symptoms have improved in 1-3 days after taking Bactrim? If so, you might indeed had UTI, but urinary symptoms from UTI may still linger in a slow disappearing fashion. If not getting better as usually expected, be reassessed for diagnostic accuracy and needed care. More? Welcome to http://formefirst. Com/onUTI. Html.

Pyuria: Presense of WBC in the urine can be infection but there are other causes. You need a urine culture and further test including an imaging. Suggest contact a kidney doc. Also need a repeat urine test, urine for eosinophils. Best of luck

Ask prescriber: These are not typical side effects of this med, but could be possible. Not sure why you are taking the med or for what expected duration. It may be that you have completed enough med and can stop now. Check with your doc.

Can bladder infection cause you to feel nausea and stomach ache with back ache.? Er put me on bactrim (sulfamethoxazole and trimethoprim)

Can bladder infection cause you to feel nausea and stomach ache with back ache.? Er put me on bactrim (sulfamethoxazole and trimethoprim)

See below: Classical symptoms for a bladder infection (cystitis): burning with urination, bladder discomfort, urinary urgency and frequency. Blood in urine, incontinence, lower abdominal and low back discomfort may also occur. If UTI involves kidney (pyelonephritis): fever, chills, nausea, vomiting, mid-back/flank pain, feel sicker. Bactrim (sulfamethoxazole and trimethoprim) good initial choice for either. Kidney stone can mimic UTI symptoms.

Taking bactrim (sulfamethoxazole and trimethoprim) and flagyl for diverticulitis. Horrible nasuea, headache and chest discomfort, body aches and just feel sick. Should I stop the med?

Taking bactrim (sulfamethoxazole and trimethoprim) and flagyl for diverticulitis. Horrible nasuea, headache and chest discomfort, body aches and just feel sick. Should I stop the med?

No: While nausea is a common adverse effect of almost any medication, the other symptoms you describe are not likely to be caused by these antibiotics. They could be caused by worsening infection, but an exam is necessary to make that determination. Seeing a doctor (preferably the prescribing doc) without delay is important in this situation.

You should have been: Feeling a lot better by now. You may be developing an abscess or other complication. Reevaluation would be important if the treatment is not being clinically effective. See your health care provider for this.

Ask your doctor: Problems like these can only be correctly handled by your doctor in person. He/she needs to listen to you, perform an examination and possibly run labs or other tests. That's the only way he/she can find out what's going on and what to do about it.

I took Bactrim (sulfamethoxazole and trimethoprim) to treat UTI for three days. I am worse. Now have Vomiting, nausea, cramps, burning urination, fever, and low temps of 96.4. What could this be? Could it be a kidney infection?

I took Bactrim (sulfamethoxazole and trimethoprim) to treat UTI for three days. I am worse. Now have Vomiting, nausea, cramps, burning urination, fever, and low temps of 96.4. What could this be? Could it be a kidney infection?

Worsening UTI: Yes, these could be signs of a kidney infection, or a bladder infection that is not sensitive to Bactrim (sulfamethoxazole and trimethoprim). The prescribing doctor needs to hear about this immediately, because someone who is vomiting cannot keep down further meds. They will probably arrange a late add-in clinic appointment or ER visit.

I'm on bactrim and everytime I smoke it makes me feel really nauseous, should I quit while I'm taking the medication?

I'm on bactrim and everytime I smoke it makes me feel really nauseous, should I quit while I'm taking the medication?

Good question: Your question should be, what is more important, your health or your need to smoke. This symptom of nausea is a wake up call TO STOP SMOKING forever and continue to take the Bactrim to rid yourself of the infection. I know it can be hard to stop smoking, but as is said the journey of a long life starts with the first step and that step is to stop smoking to avoid cancer & lung disease.
