What should I discuss with my veterinarian while considering Lisinopril?
Talk to your veterinarian about what type of outcome is expected. Have your veterinarian explain the other treatment options that may be available to treat your pet's condition. Understand what type of monitoring may be necessary while your pet is taking Lisinopril.
Tell your veterinarian if your pet has kidney disease, blood abnormalities, a vascular disease such as systemic lupus erythematosis (SLE), may be pregnant, or may be used for breeding.
Notify your veterinarian of any other medications or supplements your pet is taking. Also if your pet has had any reactions to previous medications.
What should I do if I miss a dose?
If you miss a dose, give it as soon as you remember. If it is almost time for the next dose, skip the one you missed and go back to the regular schedule. Do not give two doses at once.
What is the most important information I should know?
Give Lisinopril exactly as your veterinarian prescribes. Do not stop the medication or decrease the dose unless instructed to do so by your veterinarian. If your pet experiences diarrhea, vomiting, or the symptoms worsen while on Lisinopril, contact your veterinarian.
Who should not take it?
Do not use in animals who are hypersensitive (allergic) to this drug or other
ACE inhibitors, such as enalapril.
Not for use in pregnant and lactating animals (female animals nursing their young).
Use with caution in animals with kidney disease, low blood sodium levels, or
lupus.
What side effects may be seen when taking Lisinopril?
You may see loss of appetite, vomiting, and diarrhea. You may also see low blood pressure, which may cause weakness or collapse; kidney dysfunction, which may cause increased thirst and/or changes in urination; and abnormally high potassium levels, which may cause weakness, a slow heart rate, and a weak pulse. Contact your veterinarian if your pet has any of these signs.
If your pet experiences an allergic reaction to the medication, signs may
include facial swelling, hives, scratching, sudden onset of diarrhea, vomiting, shock, seizures, pale gums, cold limbs, or coma. If you observe any of these signs, contact your veterinarian immediately.
How is it stored?
Store in a tight, light-resistant, childproof container at room temperature. Keep out of reach of children and pets.
What should I do if I know of or suspect there has been an overdose?
The most common sign of an overdose is weakness. May also see any of the other side effects listed above.
If you know or suspect your pet has had an overdose, or if you observe any unusual signs in your pet, contact your veterinarian immediately.
What should I avoid when giving my pet Lisinopril?
Consult with your veterinarian before using Lisinopril with any other medications, including vitamins and supplements, potassium supplements or potassium-sparing diuretics, nonsteroidal anti-inflammatory drugs (NSAIDs) e.g., aspirin, indomethacin, etodolac (EtoGesic), carprofen (Rimadyl), and deracoxib (Deramaxx), since interactions may occur.
This medication is usually given along with furosemide (Lasix, Salix) and digoxin. Diuretics (like Lasix) and other vasodilators given with Lisinopril may increase the risk of low blood pressure. Your veterinarian may change the dose of diuretics when adding Lisinopril to the treatment regimen.
It is important your pet does not become dehydrated while taking Lisinopril. Make sure your pet has access to clean drinking water while taking this medication. High potassium levels may develop if potassium supplements, or potassium sparing diuretics, are given at the same time as Lisinopril.
