What should I discuss with my veterinarian while considering Proin?

Tell your veterinarian if your pet has glaucoma, enlarged prostate, hyperthyroidism, diabetes mellitus, heart problems, high blood pressure; is pregnant; or if you intend to breed your pet.
Notify your veterinarian of any other medications or supplements your pet is taking. Also tell your veterinarian if your pet has had any reactions to previous medications.

What should I avoid when giving my pet Proin?
Consult your veterinarian before using Proin with any other medications, including vitamins and
supplements, ephedrine, epinephrine, or beta-blockers (like propranolol), since interactions may occur.
Do not use with or within 2-5 weeks of using monoamine oxidase inhibitors (MAOIs) such as selegiline
(deprenyl, Anipryl), isoniazid, or amitraz (an ingredient in some flea collars and in Mitaban, used to treat
mange). Consult your veterinarian before using other medications or tick collars along with Proin.
There is an increased risk of high blood pressure if used with non-steroidal anti-inflammatory (NSAID) drugs (e.g., aspirin, carprofen (Novox or Rimadyl), etodolac (EtoGesic), meloxicam (Metacam), firocoxib
(Previcox), deracoxib (Deramaxx), tepoxalin (Zubrin) or tricyclic antidepressants (e.g., amitriptyline or
clomipramine). There is also an increased risk of irregular heart rhythms if used with digoxin.
