Is a written prescription worth it for this medicine?

The honest answer depends on how often you buy it. Prescription fees are being capped (£21 for a first item), and one prescription can cover repeat supplies, so the fee spreads across the year.

Illustrative only. Assumes one prescription fee per year covering repeat supplies; prescription validity and repeat arrangements are your vet's clinical decision, and practice fees vary until the caps take effect. Not veterinary or financial advice.
