Side Effects. Drontal has very few side effects and is generally safe. Some cats may vomit after receiving the dewormer. Rarely, a cat might appear disoriented or wobble around for a short time after taking Drontal. If your cat exhibits any side effects, call your veterinarian.
Other side effects may also occur. Talk to your veterinarian about any side effect that seems unusual or bothersome to the animal. What other drugs will affect Drontal Plus: Do not give Drontal Plus to your pet if already giving an alternate dewormer medication unless directed to by your veterinarian.
