2 Replies RSS
I am taking sulfamethoxazole-TMP DS tabs for two 2 weeks now for my UTI. Doctor said it takes more for it to work. The only symptom I have is frequent urination or the urge to pee and microscopic hematuria. Does it take that long for the infection to get cured? ## My doctor gave me only 3-day tabs. For same UTI w/o blood. 2 weeks seems too long ## It can vary depending on the type of bacteria that has caused the infection and the severity of the infection, so it is best to follow your doctor's instructions.

Infected boil
2 Replies RSS
Can I take ip 272 antibiotics for infected skin boil? And up to how many antibiotics can I take in a day? ## I am 26 years old. I have ampicillin tryhydrate capsule 250 mg. How many milligrams of ampicillin can I use for the boil? ## @Daniel, IP 272 is identified as Sulfamethoxazole + Trimethoprim DS (800 mg / 160 mg). And the answer your question is yes, this antibiotic in particular is often prescribed for tissue infections such as boils. However the protocol for proper dosing and administration should probably be left for your prescribing doctor to decide, based on the severity of the infection and other important factors. @Wale, From what I've researched, Penicillin derived antibiotics such as Ampicillin trihydrate are widely prescribed for treating boils. However, like Daniel...

Lingering chest congestion
1 Reply RSS
I had a cold but now I have lingering chest congestion that builds up in lumps in my throat (thick slimy) and gags, choke, and make me feel like its drowning me when I am sleeping - I have to jump up out of bed and cough ad spit it out. This is different from regular cold and congestion which was usually watery. I have 8 Sulfamethoxazole =TMP DS pills and was wondering if it could help loosen the congestion? ## No, that medication is an antibiotic that is used to treat, or prevent bacterial infections. The FDA lists its typical side effects as possibly including nausea, dizziness, headache, non-allergic skin rash, and diarrhea. It would be best to consult your doctor, so they can provide an appropriate solution. Has this ever happened, before? Are you on any medications?
