About This Item

  • A compounded oral suspension (5 mg/mL) containing sildenafil citrate, commonly prescribed by veterinarians to help manage pulmonary hypertension in dogs and cats.
  • 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 vasodilation in the lungs and supporting better oxygenation and exercise tolerance.

How is the strength of this suspension measured?

This compounded suspension is 5 mg of sildenafil citrate per 1 mL of liquid. Your veterinarian will direct the exact milliliter amount to give for each dose.

Can sildenafil be given with other heart medications?

It is often used alongside other cardiac or respiratory medications, but only under veterinary supervision. Always tell your veterinarian about all medicines and supplements your pet receives; combinations with nitrates, other PDE5 inhibitors, or certain blood pressure medications may increase the risk of low blood pressure.

What side effects should I watch for?

Some pets may experience gastrointestinal upset (vomiting, diarrhea), decreased appetite, lethargy, or restlessness. Contact your veterinarian promptly if you notice weakness, fainting, collapse, severe breathing difficulty, or any unusual signs.

How long will my pet need to take sildenafil?

Duration varies by the underlying condition and your pet’s response. Many pets require ongoing therapy, which should be periodically re-evaluated by your veterinarian.

How should I store the suspension?

Follow the storage directions on the dispensing label. Keep the bottle tightly closed, shake well before each use, and do not use past the beyond-use date.

What should I do if I miss a dose?

Give the missed dose when you remember unless it is close to the next scheduled dose. Do not give two doses at once; contact your veterinarian if you are unsure.
