Medication library / Transdermal gel (PLO)

Dosage form

Compounded Transdermal Gels for Pets (PLO)

Transdermal gels are rubbed onto the hairless inner ear, which is useful for cats and dogs who won't take pills. They come in pre-measured syringes. Wear a glove when applying and alternate ears if your veterinarian directs. Not every medication is absorbed well through the skin, so your veterinarian decides when this form is a good fit.
