Otrim Oral Suspension

Otrim Oral Suspension is a prescription antibiotic suspension containing sulfamethoxazole and trimethoprim in the strength listed on the bottle by Zydus Healthcare, India. It belongs to the sulfonamide antibiotic combination class, often called co-trimoxazole or TMP-SMX. Doctors prescribe Otrim Oral Suspension to treat certain bacterial infections, including some ear, urinary tract, intestinal, and respiratory infections, when the bacteria are expected to respond to this medicine.

How it works: Sulfamethoxazole and trimethoprim work together by blocking two steps bacteria need to make folate, a nutrient they use to grow and multiply. As a suspension, Otrim Oral Suspension lets the medicine be measured accurately and taken by mouth in a form that is easier to swallow.

Because Otrim Oral Suspension is a liquid suspension, it is useful for people who have trouble swallowing tablets and for doses that need to be measured more flexibly. This specific strength is chosen by a doctor when the exact amount needed fits the labeled bottle concentration and the patient’s age, weight, and infection type; it is not meant to be swapped with another strength without medical guidance.

• Urinary tract infections
• Ear infections
• Certain respiratory infections
• Traveler’s diarrhea due to susceptible bacteria
• Other doctor-diagnosed bacterial infections

• Shake the bottle well before each dose so the medicine is evenly mixed.
• Measure each dose carefully with a marked oral syringe or dosing cup, not a kitchen spoon.
• Take Otrim Oral Suspension at evenly spaced times each day to keep levels steady.
• It may be taken with food or milk if it upsets your stomach.
• Finish the full course even if you feel better early, unless your doctor tells you to stop.
• If you miss a dose, take it when you remember unless it is close to the next dose; do not double up.

The dose for Otrim Oral Suspension depends on the labeled bottle concentration, the infection being treated, and the patient’s age and weight. It is usually taken 2 times a day, but some infections may require a different schedule; the prescriber determines the exact dose and the maximum daily amount. Because this is a specific suspension strength, the amount in each measured dose should be matched carefully to the prescription.

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