Frequently asked questions
Frequently asked questions
Can I refill my pet's prescription through an online vet?
Yes — RexVet's licensed veterinarians in Florida, New York, and Virginia can refill most common pet medications via a $64.99 video visit. Prescriptions are filled through RexVet's in-house pharmacy (RexVetRx) with same-day delivery in most ZIP codes, or sent to any local pharmacy that participates in e-prescribing.
What medications can a RexVet online vet prescribe?
RexVet vets can prescribe common dog and cat medications including Apoquel (allergies), Cytopoint (allergies), Carprofen and Rimadyl (pain), Gabapentin (pain and anxiety), Trazodone (anxiety), Prednisone and Prednisolone (inflammation), Cerenia (anti-nausea), Vetmedin (heart disease), Solensia (cat arthritis), Mirataz (appetite stimulant), and more. Controlled substances are not prescribed at RexVet.
How much does an online vet prescription cost at RexVet?
The video visit itself is a flat $64.99 — no membership, no surge pricing, 24/7 availability. The cost of the medication itself depends on the drug, dose, and pharmacy. RexVetRx prices are competitive with chain pharmacies, and most major pet insurance plans reimburse for telehealth-prescribed medications.
Are RexVet's medication guides reviewed by a veterinarian?
Yes — every medication guide is reviewed by Dr. Tiffany Delacruz, DVM. Drug information cites FDA labels, Merck Veterinary Manual, and peer-reviewed veterinary literature. Last reviewed: 2026-06-03.

Visit our dedicated dosage-by-weight hub at /medications/dosage. We have 56 dosage guides covering 6 dog drugs across 6 weight classes (10/20/30/50/70/100 lb) and 5 cat drugs across 4 weight classes (5/8/12/18 lb). Each guide explains the dosing principle — the actual prescription dose comes from a licensed vet visit.
