Bactrim combines two antibiotics, sulfamethoxazole and trimethoprim, and is prescribed to address various bacterial infections, including those affecting the middle ear, urinary tract, respiratory system, and intestines. Additionally, it is employed for both prevention and treatment of a specific form of pneumonia known as pneumocystis-type pneumonia. It's important to note that this medication is not suitable for children under 2 months old due to the potential for serious side effects. It's crucial to understand that this medication is effective only against certain types of infections and will not treat viral infections like the flu. Misuse or unnecessary use of any antibiotic can reduce its effectiveness over time.
How to use Bactrim DS

The dosage depends on your medical condition and how you respond to treatment.
For optimal results, administer this antibiotic at regular intervals. To help you remember, take it at the same time(s) every day.
Continue taking this medication until you have finished the full prescribed amount, even if symptoms improve within a few days. Ceasing the medication prematurely could lead to a resurgence of the infection.
