BACTRIM

What Bactrim Is

Bactrim is a trade name of co-trimoxazole, a combined antibiotic consisting of sulfamethoxazole (5 parts) and trimethoprim (1 part). The combination of these two substances is claimed to be more effective in treating bacterial infections than its components used individually. Bactrim is used for treating infections of the urinary tract, skin, respiratory tract, gastrointestinal tract, MRSA (methicillin-resistant Staphylococcus aureus), travelers’ diarrhea, cholera, sepsis, recurrent retinochoroiditis. It is also sometimes used for treatment and prevention of toxoplasmosis and pneumocystis pneumonia in patients with immunosuppression, in particular with HIV/AIDS.

Recommendations for Use, Dosage and Overdose

Bactrim is usually administered orally and in some cases, intravenously. Take Bactrim only by doctor’s prescription and in strict accordance with it. Follow all instructions on the label and read all guides provided in the box.

Drink plenty of fluids to prevent renal problems while using Bactrim treatment. Use the medicine for the full prescribed course, even if the symptoms have improved. Do not skip doses either as it can increase the risk of an antibiotic-resistant infection. Bactrim can interfere with the results of a range of medical tests. Inform your doctor if you are using this medication.

In pediatrics, Bactrim doses are calculated depending on the child’s weight. Use only recommended doses in children’s treatment. If you miss a dose by accident, take it as soon as you can. However, if it is almost time for your next one, skip the missed dose. Do not take two doses at a time. If you overdose, seek emergency medical attention at once. The symptoms can include fever, loss of appetite, vomiting, blood in urine, confusion, loss of consciousness, jaundice.
