The recommended Bactrim dose for treating urinary tract infections, ear infections, or Pneumocystis carinii pneumonia in children is determined by weight. For Pneumocystis carinii pneumonia prevention, the dose is based on body surface area (which your child's healthcare provider will calculate using your child's weight and height). Bactrim should never be used in children under the age of two months old.
Some considerations for people taking Bactrim include the following:
- Bactrim comes in tablet form. It is taken by mouth, usually twice a day (although it is taken as frequently as four times daily or as infrequently as once daily for certain uses).
- You can take this medication with food or on an empty stomach. If it bothers your stomach, try taking it with food.
- Bactrim can be taken at any time of the day; however, be sure to take the medication at the same time(s) each day. For instance, if you take it twice daily, it is best to evenly space the doses, taking a dose every 12 hours.
- For the medication to work properly, it must be taken as prescribed. Bactrim will not work if you stop taking it too soon.
- If you are unsure about anything related to your dosage or Bactrim dosing in general, please talk with your doctor, nurse, or pharmacist.
