  • Sildenafil Citrate

What is sildenafil used for in dogs and cats?

Sildenafil is commonly prescribed to help manage pulmonary hypertension in dogs and cats by promoting relaxation of the pulmonary blood vessels, which may support easier breathing and activity tolerance as directed by your veterinarian.

How quickly will my pet respond to sildenafil?

Response time varies by pet and the underlying cause of pulmonary hypertension. Some pets may show improvement within days once a consistent dosing plan is established, but your veterinarian will determine expectations and monitoring needs.

How do I give this compounded sildenafil suspension?

Shake the bottle well, then measure the prescribed amount with an oral dosing syringe and give by mouth as directed by your veterinarian. Ask your vet whether to give with or without food based on your pet’s needs.

What side effects should I watch for?

Possible side effects can include gastrointestinal upset (vomiting, diarrhea), decreased appetite, or lethargy. Rarely, low blood pressure may occur, which can present as weakness or fainting. Contact your veterinarian if you notice concerning or persistent effects.

Does sildenafil interact with other medications?

Yes, it can interact with other blood pressure or heart medications and certain vasodilators. Always tell your veterinarian about all medicines and supplements your pet receives so they can assess for interactions.

What if I miss a dose?

If a dose is missed, ask your veterinarian for guidance. Do not double up or adjust the schedule without veterinary advice.

How should I store the suspension and how long does it last?

Follow the storage directions on the label (such as temperature requirements) and use the medication before the beyond-use date provided for the compounded suspension. Do not use it past that date, and keep the bottle tightly closed.
