When parents or caregivers search for “Maxtra drops dose per kg,” they are usually looking for one thing: safe, precise dosing for infants and young children. But most online answers oversimplify dosage or ignore the pharmacological nuance behind it.
Maxtra Oral Drops is a combination of Chlorpheniramine and Phenylephrine. This medicine is used to treat the signs of common cold and allergies, such as a runny nose, itching, cough, nasal congestion, and watery eyes, in children. It reduces swelling of the blood vessels in the nasal passages and helps ease a blocked or stuffy nose. It also stops the action of a substance in the body that causes allergic symptoms.
Maxtra Oral Drops are NOT strictly dosed per kg like antibiotics or paracetamol.

Expert Insight – What Pediatricians Actually Do
Doctors prioritize age + symptom severity
Weight is used as a secondary safety check
Lowest effective dose is preferred
This is why you’ll rarely see a strict formula like:
“X drops per kg”
Because Maxtra isn’t designed for that dosing model.
| Factor | Importance |
| Age | Primary |
| Symptom severity | High |
| Weight | Secondary |
| Medical history | Critical |
Pediatricians avoid strict per kg dosing for combination drugs like Maxtra.
Better Alternatives
Depending on symptoms, doctors may recommend:
- Saline nasal drops (safest first-line)
- Single-ingredient antihistamines
- Steam inhalation (for older children)
These often reduce the need for combination drugs.

Final Verdict
Maxtra Drops are effective but not simple medications. As a combination drug, their dosing must prioritize safety over mathematical precision rather than relying on strict weight-based calculations.
