Methoxaprim Oral Suspension

Methoxaprim Oral Suspension is a prescription antibiotic suspension made with sulfamethoxazole and trimethoprim. Each bottle contains the labeled amount of these two ingredients in liquid form, which makes it easier to measure and swallow than tablets for some patients. It belongs to the sulfonamide/folate-inhibiting antibiotic class and is used to treat certain bacterial infections, not colds or flu. Methoxaprim Oral Suspension is commonly prescribed for infections such as urinary tract infections, some ear infections, bronchitis, and certain types of skin or intestinal infections when the bacteria are likely to respond.

How it works: Sulfamethoxazole and trimethoprim work together to block two steps bacteria need to make folic acid, which helps stop the germs from growing. In suspension form, Methoxaprim Oral Suspension is swallowed as a measured liquid dose so the medicine can be absorbed and start working through the body.

Because Methoxaprim Oral Suspension is a liquid, the dose can be adjusted more precisely for children or adults who need a tailored amount. This form is often chosen when swallowing tablets is difficult, when a smaller or measured dose is needed, or when a doctor wants flexible dosing over a treatment course. Since it is the labeled suspension strength only, your prescriber uses the bottle's concentration to calculate the exact milliliters per dose.

• Urinary tract infections
• Ear infections
• Bronchitis
• Traveler’s diarrhea due to susceptible bacteria
• Certain skin infections
• Other bacterial infections prescribed by a doctor

• Shake Methoxaprim Oral Suspension well before each dose so the medicine is evenly mixed.
• Measure the dose carefully with an oral syringe, dosing cup, or the measuring device provided with the bottle.
• Take it exactly as prescribed and finish the full course even if you feel better.
• It may be taken with or without food, but taking it with food or a full glass of water can help reduce stomach upset.
• Drink plenty of fluids unless your doctor has told you to limit fluids.
• If a dose is missed, take it as soon as you remember unless it is almost time for the next dose; do not double up.

Methoxaprim Oral Suspension is supplied as a labeled liquid concentration, and the exact milliliters per dose depend on the infection being treated and the patient’s age, weight, and kidney function. It is usually taken every 12 hours for many infections, but the total daily amount and treatment length are decided by the prescriber; do not change the dose on your own. The maximum daily dose is determined by the doctor and should not be exceeded.

Do not change your dose or stop the medicine without speaking to your doctor.
