Description
Overview of the medicine
Dinafex 120 mg Tablet is an antihistamine used to relieve allergy symptoms such as watery eyes, runny nose, itching eyes/nose, sneezing, and hives. It belongs to a class of medications called H1 antagonists.
Uses & Indications
Dosage
Adults
120 mg or 180 mg once daily.

60 mg once daily for patients with impaired renal function (creatinine clearance < 80 mL/min).
How to Take
Take orally with water. Can be taken with or without food. Avoid taking with fruit juice.
Mechanism of Action
Fexofenadine, a peripheral H1-receptor antagonist, selectively blocks histamine H1 receptors. It does not readily cross the blood-brain barrier, resulting in a low incidence of sedation.

Primarily excreted unchanged in feces (80%) and urine (11%).
Half life
Approximately 14 hours
Absorption
Rapidly absorbed after oral administration. Peak plasma concentrations are reached in 1-3 hours.
Metabolism
Minimally metabolized (less than 5%) in the liver.
Side Effects
Contraindications
- •Hypersensitivity to fexofenadine or any component of the formulation.
Drug Interactions
Erythromycin or Ketoconazole

Storage
Store in a cool, dry place below 30°C, away from direct sunlight and moisture. Keep out of reach of children.
Overdose
Symptoms may include drowsiness, dizziness, and dry mouth. Management is symptomatic and supportive; consider activated charcoal if recent ingestion.

Pregnancy Category C. Use only if potential benefit justifies potential risk to the fetus. Caution is advised during breastfeeding as fexofenadine is excreted in breast milk.
