Due to the very low doses to be administered, and to avoid any risk of overdose, the
animal must be weighed, and the recommended doses must be respected.
Phenylpropanolamine, a sympathomimetic drug, may affect the cardiovascular
system, especially blood pressure and heart rate, and should be used with caution in
animals with cardiovascular diseases.
Care should be exercised in treating animals with severe renal or hepatic
insufficiency, diabetes mellitus, hyperadrenocorticism, glaucoma, hyperthyroidism or
other metabolic disorders.
In bitches less than 1 year old the possibility of anatomical disorders contributing to
incontinence should be considered prior to treatment.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
Phenylpropanolamine hydrochloride is toxic when ingested in higher doses. Adverse
effects may include dizziness, headache, nausea, insomnia or restlessness, and
increased blood pressure.
Accidental ingestion by a child may be fatal.
To avoid accidental ingestion, the veterinary medicinal product must be used and
