Roxee has limited cited overview evidence for Phenylpropanolamine Hcl; use the official documents and your veterinarian's instructions for product-specific decisions.
32 tracked reaction signals; 32 reported cases; 27 serious reports; 2 species groups. These are reporting and label-derived signals for interpretation with a veterinarian.
Adverse-event reports help form a watch list, but they do not prove the medication caused the reaction and they are not a risk ranking between medications.
Official labels, package inserts, and reviewed summaries carry more weight than isolated reports.
Case reports and openFDA terms are useful for pattern awareness, but they are incomplete, can include multiple exposures, and do not estimate an individual pet's probability of harm.
Unsteady walking (ataxia) (1 reports), Inappropriate defecation (1 reports), Hyperphosphataemia (1 reports), Growling (1 reports), Generalised itching (1 reports)
Digestive (2), Skin & allergy (1), Neurologic (1), Behavior (3)

Shepherd Dog - German (2), Retriever - Labrador (1), ['Terrier - Bull - American Pit', 'Dog (unknown)'] (1), Collie - Smooth-haired (1). These are report metadata, not proof that a breed is at higher risk.
Verify whether Phenylpropanolamine Hcl fits the pet's species, current diagnosis, age, weight, organ status, pregnancy/lactation status, and concurrent medications.
