Bactrim is a prescription medication including two antibiotic drugs, sulfamethoxazole and trimethoprim. It is primarily used for treating urinary tract infections, ear infections, bacterial diarrhea, chronic bronchitis and a specific type of pneumonia. Some doctors prescribe Bactrim to treat acne that has not responded to other types of therapy.
Acne Problems
Acne usually begins with overactive oil glands in the hair follicles, which leads to excessive oil on the face. Oily skin prevents dead skin cells from shedding. These cells block pores, resulting in an environment where anaerobic bacteria that cause acne can thrive. Topical and oral antibiotic medications can be effective in treating acne because they kill bacteria and prevent bacteria growth.
Bactrim Function
Trimethoprim and sulfamethoxazole interfere with the production and formation of chemicals essential for bacterial growth. A study published in a 1993 issue of the journal "Dermatology" found trimethoprim to be effective for treating acne that had not responded to two other types of antibiotics. Patients in this study took 300 mg of trimethoprim twice daily for at least 4 months, and for some, up to 8 months. A study published in "Cutis" in 2007 explains that some dermatologists prescribe the combination of trimethoprim and sulfamethoxazole to treat acne and other skin infections.
Usage
Bactrim is available in tablet and liquid form. The patient usually is instructed to take Bactrim twice a day with a full glass of water. The patient should drink several additional glasses of water every day, according to the Mayo Clinic, to help prevent certain side effects.
Side Effects
The most common side effects associated with Bactrim include lack of appetite, nausea and abdominal pain, as noted by eMedTV. Some people develop constipation, dizziness, drowsiness, headache, sleeping problems or weakness. Use of Bactrim, like other antibiotics taken for acne, can cause an oral yeast infection (thrush) or a vaginal yeast infection. Taking Bactrim also can result in anemia, which usually resolves when the patient discontinues the medication.
Warning
Bactrim can cause severe colitis, although this side effect is uncommon. Symptoms include chronic diarrhea and abdominal pain. Another unlikely side effect is a rash that may progress to blistering and peeling. Anyone who develops a rash while taking Bactrim should discontinue the medication and see a doctor. Rarely, patients taking Bactrim develop chest pain, shortness of breath, or an allergic reaction with signs of a rash or hives, difficulty breathing, and swollen throat, face or mouth.
