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.
Drontal Plus is effective not only against tapeworms, but also other types of parasitic infestations like hookworms, roundworms and whipworms. While this medication is given in one dose, a follow-up dose may be given for 1 to 3 weeks after initial treatment.
