The most commonly reported side effect of Frontline Plus is irritation or reddening of the skin in the area where the product was applied.
The makers of Frontline Plus state that skin irritation is usually nothing to worry about and will quickly fade.
However, if the irritation is severe or distressing to your pet, please do see a veterinarian for assistance.
In some cases irritation like this can be caused by allergy to the ingredients of Frontline Plus, which may mean looking for an alternative flea control product for your pet.
In other cases, irritation at the application site of Frontline Plus can be due to overdose, dosage which is higher than necessary.
Side effects after using Frontline Plus have also been linked to interactions between any other medications or insecticides which have been used on your pet.
Overdose is the main reason why the side effects in using Frontline Plus tend to happen, so you need to be very careful with that aspect.
By ensuring that you only use the right type of Frontline Plus for your pet's species, weight and type, the likelihood of seeing side effects of Frontline Plus in your pets is reduced while keeping them properly protected from parasites.
The key to avoiding side effects when using Frontline Plus on your pets is to follow the packaging instructions in the letter, and seek advice from a professional if you are unsure of the dosage to use on your pets.
