Generic Theofer XT

Common use

Theofer XT is prescribed to treat iron deficiency anemia and improve hemoglobin levels while providing bronchodilation for respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD). The iron component helps replenish iron stores, and the theophylline component relaxes airway muscles to improve breathing.

Dosage and direction

Theofer XT is usually taken orally, once or twice daily, or as directed by your doctor. Take the tablet with water, preferably after meals to reduce stomach irritation. Follow your healthcare provider’s instructions carefully.

Precautions

Inform your doctor if you have liver or kidney problems, heart disease, arrhythmias, ulcers, or hypertension. Monitor for signs of iron overload, palpitations, or gastrointestinal discomfort. Avoid taking other iron supplements simultaneously unless advised.

Contraindications

Do not use Theofer XT if allergic to iron, theophylline, or any other component of the tablet. It is contraindicated in patients with hemochromatosis, severe arrhythmias, or peptic ulcers.

Possible side effect

Common side effects include nausea, vomiting, constipation, diarrhea, headache, or mild dizziness. Serious side effects may include palpitations, rapid heartbeat, severe gastrointestinal irritation, or allergic reactions. Seek medical attention if severe symptoms occur.

Drug interaction

Theofer XT may interact with antacids, other iron supplements, certain antibiotics, and medications affecting heart rhythm. Inform your doctor of all prescription drugs, over-the-counter products, and supplements you are taking.

Missed dose

If a dose is missed, take it as soon as you remember unless it is near the time of your next dose. Do not double the dose.

Overdose

Overdose may cause severe gastrointestinal irritation, rapid heartbeat, dizziness, or iron toxicity. Seek immediate medical attention if overdose is suspected.

Storage

Store Theofer XT at room temperature, away from heat, moisture, and light. Keep tablets in the original container and out of reach of children.
