Frequently Asked Questions

How often should I adjust medication dosages?

Dosages should be reviewed every 4-6 weeks, or more frequently if symptoms change significantly.

What should I do if a patient misses a dose?

For most medications, missed doses should be taken as soon as remembered, unless it's almost time for the next dose. Never double the dose to make up for a missed one.

Are there weight-based dosage formulas for all medications?

No, some medications have fixed dosages regardless of weight, while others use body surface area or other factors.

How do I calculate dosages for pediatric patients?

Pediatric dosages often use age-based formulas rather than weight-based calculations. Consult the medication's pediatric dosing guidelines.
