Treatment depends on your cat’s symptoms and their severity: supportive care helps maintain hydration, nutrition and comfort, while a veterinarian may prescribe antivirals for certain eye or respiratory problems or antibiotics for a suspected secondary bacterial infection. Trouble breathing, dehydration or inability to eat needs prompt veterinary attention.
Sneezing and eye discharge do not prove that FHV-1 is the cause. Other infections can produce similar signs, so a veterinarian should assess your cat and decide whether testing or treatment is needed.

What FVR affects and how it is diagnosed
FVR is associated with FHV-1 and commonly affects the upper respiratory tract and eyes. Signs can include sneezing, nasal or eye discharge, conjunctivitis, corneal inflammation or ulcers, and fever. Feline respiratory disease can also involve feline calicivirus and other infectious agents, so symptoms alone may not identify the cause. Cornell’s Feline Health Center describes diagnosis as based on the signs and, when appropriate, tests such as PCR or virus isolation.

What you can do at home while arranging care
Home care is supportive; it does not eliminate the virus or replace an examination when symptoms are significant. Follow your veterinarian’s instructions, and contact the clinic if your cat’s intake or condition worsens.
Encourage food and fluids
Keep fresh water available and offer food your cat will readily eat. Nasal congestion can reduce a cat’s ability to smell food, which may lower appetite. Ask your veterinarian for guidance if your cat is eating or drinking less than usual; severe cases may need fluids or assisted feeding.

Gently clean discharge
Use a clean, damp cloth to wipe away nasal or eye discharge as needed. A veterinarian may recommend saline nose drops or nebulization to loosen thick secretions. Do not put eye drops or other products in your cat’s eyes unless a veterinarian directs you to do so.

Consider humidified air for congestion
VCA Animal Hospitals notes that increased environmental humidification may help a congested cat; a short stay in a steamy bathroom is one option. A room humidifier is another way to add moisture to the air. Humidification is only a comfort measure, not an antiviral treatment, and it is not a substitute for urgent care if breathing is difficult. VCA’s FHV-1 guidance discusses humidification and other supportive care.

When a veterinarian may prescribe medication
Antivirals for selected FHV-1 disease
Antivirals may be considered for particular cases, especially corneal or conjunctival disease and some acute respiratory signs. A veterinarian chooses whether treatment is suitable and whether it should be given as an eye medication or by mouth. Recurrent eye inflammation may also need veterinarian-directed antiviral treatment.
Antibiotics for suspected bacterial complications
Antibiotics do not treat FHV-1 itself. A veterinarian may prescribe them if a secondary bacterial infection is suspected based on the examination and clinical signs.

Do not start human or leftover medicines
Do not give human cold medicines, leftover antibiotics, antiviral drugs, eye medicines or supplements without veterinary direction. L-lysine is not an established treatment: Cornell notes that evidence is controversial, with studies suggesting it may be ineffective or may worsen symptoms and viral shedding.
Signs that need prompt veterinary care
Contact a veterinarian promptly if your cat has significant eye symptoms, is eating or drinking poorly, or seems unusually quiet or weak. Seek urgent care for breathing difficulty, dehydration or inability to eat. A cat with severe disease may require hospitalization, oxygen, fluids or assisted feeding. Kittens and cats with substantial eye involvement warrant particular attention.

Why symptoms can return and how to reduce spread
FHV-1 can remain in a cat after the initial illness and flare again, often during stress. Cornell reports that up to 97% of cats are exposed to feline herpesvirus during their lifetime; up to 80% of exposed cats develop lifelong infection; and up to 45% of infected cats periodically shed virus. These figures are reported on Cornell’s page, whose publication date is not specified.
The virus can spread in respiratory droplets and on contaminated objects. Keep an affected cat apart from other cats where practical, and wash your hands after handling discharge or shared items. Reducing overcrowding and avoidable stress may help limit exposure or the chance of a flare.
Vaccination against feline herpesvirus is recommended for all cats, but it does not prevent every infection. Cornell says vaccination reduces disease severity and viral shedding. Discuss vaccine timing and choice with your veterinarian, taking your cat’s health, exposure risk and vaccination history into account. Cornell’s vaccine information provides background, while your veterinarian can advise on an individual schedule.
What to expect from treatment
There is no single medication plan for every cat with suspected FVR. A cat with mild signs may need supportive care and monitoring; eye disease, suspected bacterial complications, poor food or water intake, or severe breathing signs change the treatment decision. The veterinarian’s examination helps determine whether home support is appropriate or prescription treatment and hospital care are needed.
