Dimetindene 1 mg/mL (drops) Dosage Calculator

How to Calculate Dimetindene 1 mg/mL (drops) Dose

This calculator determines the Dimetindene dose for treating allergic reactions, using a concentration of Dimetindene 1 mg/mL (drops, 1 drop = 1 mg), based on the patient’s weight (for pediatrics) or age group:

Dose in drops and mg (based on Dimetindene component):

Pediatrics ≥1 year: 2 drops/kg divided into 3 doses (Max 40 drops/dose) PO TID

Adults: Usual dose is 20 to 40 drops (1–2 mg) PO TID

Drops Calculation:

For pediatrics: Drops = Weight (kg) × 2, divided into 3 doses (max 40 drops/dose), with integer weights like 10 kg resulting in exactly 6 drops PO TID

Where:

Weight: Patient’s weight in kilograms or pounds (minimum ~5 kg for pediatrics ≥1 year, automatically converted to kg) for pediatrics; not used for adults.
Dosage Regimen: Select 2 drops per kg divided into 3 doses (Max 40 drops/dose) for pediatrics.
Concentration: Dimetindene 1 mg/mL (1 drop = 1 mg).

Administer three times daily (TID) for allergy symptoms. ⚠️ Always consult a healthcare provider.
