Description Proper Usage Finish the full course of treatment prescribed by your physician. Even if your symptoms disappear after a few days, stopping this medication prematurely may result in a return of the symptoms. This medication works most effectively when it is maintained at a constant level in your blood or urine. To help keep the amount constant, do not miss any doses. It is best to take the doses at evenly spaced times during the day and night. For maximum effectiveness, four doses per day would be spaced at six-hour intervals. Precautions If taken for a long time, sulfamethoxazole and trimethoprim combination may cause blood problems. It is very important that your physician monitor your progress at regular visits. This medication can cause changes in the blood, possibly resulting in a greater chance of certain infections, slow healing, and bleeding of the gums. Be careful with the use of your toothbrush, dental floss, and toothpicks. Delay dental work until your blood counts are completely normal. Check with your dentist if you have questions about oral hygiene during treatment. This medication may cause your skin to become more sensitive to sunlight. Stay out of direct sunlight during the midday hours, wear protective clothing, and apply a sun block product that has a skin protection factor (SPF) of at least 15. Sulfamethoxazole and trimethoprim combination has not been reported to cause birth defects or other problems in humans. Studies in mice, rats, and rabbits have shown that some sulfonamides cause birth defects, including cleft palate and bone problems. Studies in rabbits have also shown that trimethoprim causes birth defects, as well as a decrease in the number of successful pregnancies. Sulfamethoxazole and trimethoprim pass into breast milk. This medication is not recommended for use during breastfeeding. It may cause liver problems, anemia, and other problems in nursing babies. Possible Side Effects Less common side effects that should be reported to your physician immediately: itching; skin rash; aching of muscles and joints; difficulty in swallowing; pale skin; redness, blistering, peeling, or loosening of skin; sore throat and fever; unusual bleeding or bruising; unusual tiredness or weakness*; yellow eyes or skin. *Since it may be difficult to distinguish between certain common symptoms of MS and some side effects of sulfamethoxazole, be sure to consult your health care professional if an abrupt change of this type occurs. |
