Sulfatrim and Sulfatrim DS tablets
This product is taken orally.
Why is it prescribed?
Sulfatrim is used to treat many infections caused by susceptible bacteria. This material will be limited to infections of the respiratory tract (e.g. pneumonia, bronchitis).
Use exactly as prescribed.
Sulfatrim tablets are available in both regular and double strength (DS). The DS tablets are large and can be difficult to swallow. They can be broken into pieces and swallowed.
Take Sulfatrim at even intervals around the clock as prescribed (e.g. every 12 hours translates to twice a day) until all the prescribed medication has been taken. Failure to take the complete course can result in incomplete elimination of the bacteria which can lead to a relapse of the infection. The prescribed course generally lasts a few days longer than symptoms of the infection (e.g. fever). Treatment usually lasts 5 to 14 days. If you miss a dose of this medicine, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take a double dose(unless you have been instructed to do so). Contact your pharmacist if you are not sure what to do.
Sulfatrim may produce allergic reactions. These may range from a mild rash or itching to a life-threatening reaction. Contact your doctor or pharmacist if you experience rash, itching, fever, difficulty breathing, chest tightness or anything else that alarms you.
Store at room temperature protected from light and moisture.

Sulfatrim tablets are a combination of two antibiotics called trimethoprim and sulfamethoxazole. These antibiotics work together by inhibiting two critical steps in the production of bacterial folic acid. The resulting decrease in folic acid interferes with the production of genetic building blocks and proteins of bacteria. The effectiveness of Sulfatrim depends on factors such as dose, concentration in the blood as well as other body fluids and tissue, and susceptibility of the organism. Infections caused by bacteria that are not sensitive to Sulfatrim will not show improvement after taking this medication.
Along with its needed effects, Sulfatrim may cause some unwanted or undesirable effects. Generally, Sulfatrim is well tolerated and many people will not experience unwanted effects. The frequency and severity of these effects is dependant on many factors including dose, duration of therapy and individual susceptibility. Possible unwanted effects include:
- loss of appetite
- mouth sores or swelling of the tongue
- nausea or vomiting
- Increased sensitivity of skin to sunlight
- joint or muscle pain
- difficulty in swallowing
- pale skin
- sore throat and fever
Allergic reactions can occur with Sulfatrim use. People with a history of allergy, asthma, hay fever or hives seem to be more susceptible to these reactions. The reaction can be immediate and severe. Allergic symptoms include wheezing, hives, itching, swelling, spasms in the throat and breathing tubes, joint and muscle pain, difficulty breathing, fever and skin rashes. Nausea and vomiting are not symptoms of an allergic reaction.
Taking the antibiotic repeatedly or for prolonged periods may result in bacterial or fungal overgrowth which can lead to a second infection. When this occurs, the Sulfatrim may need to be stopped and another antibiotic prescribed to treat the new infection.
Elderly people may be at an increased risk for side effects, especially when complicating conditions exist (such as kidney or liver disease).
Drink enough fluids (e.g. water) to increase urine flow.
Sulfatrim may cause your skin to be more sensitive to sunlight. Exposure to sunlight, even for brief periods of time, may cause skin rash, itching, redness or severe sunburn. Stay out of direct sunlight, wear protective clothing and apply sun block. Do not use a sunlamp or tanning bed while on this medication.
