What Is Cidofovir?
Cidofovir is a potent antiviral that treats viral eye infections by blocking virus replication. It is especially effective against feline herpesvirus (FHV-1), a leading cause of chronic eye problems in cats.
Our cidofovir drops are compounded via a PCAB-accredited partner in a USP <797>-compliant, ISO-class sterile facility, ensuring purity and consistency.
From custom strengths to preservative-free options, Rock Ridge Pharmacy provides eye drops that are veterinarian-prescribed, pharmacist-guided, and pet-approved.

FAQs About Cidofovir Eye Drops at Rock Ridge Pharmacy
Do I need a prescription?
Yes. Cidofovir is only available with a veterinarian's prescription after proper diagnosis of viral eye infection.
How much will this cost per treatment course?
A typical 2–4 week treatment course costs $85–125, depending on strength and duration. This is often more cost-effective than repeated treatments for chronic infections.
Does pet insurance cover antiviral medications?
Many pet insurance plans cover prescription medications for infections when medically necessary. Keep receipts for potential reimbursement.
How quickly does cidofovir work?
Some improvement may be seen within a few days, but full results typically take 1–2 weeks of consistent treatment. Complete the full course even if symptoms improve.
Is this safe for long-term use?
When monitored by your veterinarian, cidofovir can be used for extended periods in cats with chronic herpesvirus infections.
Can this be used in dogs or other animals?
While most commonly prescribed for cats with herpesvirus, your veterinarian may prescribe it for other species when appropriate.
What if my cat fights the eye drops?
Our pharmacist can provide restraint techniques. Try wrapping in a towel, staying calm, and offering treats afterward. Some cats tolerate it better with two people helping.
Is it preservative-free?
Yes. Our cidofovir is formulated in a gentle, preservative-free artificial tears base to protect sensitive, infected eyes.
Can I travel with this medication?
Yes—store in a cooler with ice packs to maintain refrigeration. Essential for maintaining antiviral potency.
What if I accidentally get it in my eye?
Rinse thoroughly with clean water and contact your physician if irritation persists. While formulated for pets, avoid human contact.
How is this different from other antiviral eye drops?
Cidofovir is specifically effective against herpesvirus and has longer-lasting antiviral action compared to some alternatives.
What if my cat's infection doesn't improve?
Our pharmacist will work with your veterinarian to adjust concentration, extend treatment duration, or consider combination therapy.
Can this prevent future outbreaks?
In some cats with chronic herpesvirus, maintenance therapy may help reduce frequency and severity of recurrent infections.
Are there any drug interactions?
While topical cidofovir has minimal systemic absorption, inform your veterinarian about all medications your cat receives.
What if the medication accidentally freezes?
Do not use frozen medication as it may affect antiviral potency. Contact us for immediate replacement.
How do I know if the infection is clearing?
You should notice decreased discharge, less squinting, clearer eyes, and your cat seeming more comfortable. Your vet may recheck during treatment.
Is this more expensive than commercial products?
Since no commercial cidofovir eye drops exist for pets, compounding is the only option. The cost is reasonable considering the specialized nature and effectiveness.
What payment options are available?
We accept cash, credit cards, CareCredit, and can work with pet insurance for direct billing. Payment plans available for extended treatments.
