Now, let us consider some of the Nexgard Spectra features that are not exactly ideal, and may affect your decision. These are as follows:

Prescription required

Nexgard Spectra can only be acquired if you have a prescription from your veterinarian. Even if you are ordering online, you will be required to present a prescription.

This can limit one’s decision as sometimes the problem is too obvious to not require a solution, and procuring a prescription feels like unnecessary formalities.

Lack of Longitudinal Studies

Though there are a few short term studies done, there aren’t many good longitudinal studies done regarding the safety of such treatment measures.

This is mainly because Nexgard Spectra is a relatively new product in the market. However, the lack of such long term studies can cause owners to pause with concern.

Side Effects

Every dog is different and sometimes their bodies may not react well to Nexgard Spectra. If the dog has a reaction to the ingredients present in the medication, there is no way to remove it from the system the way tropical solutions can be washed off using soap.

Though it is rare, these side effects can include vomiting, lethargy, diarrhea, seizures, itching, loss of coordination, swelling of the face, and loss of appetite.

According to an EMA study, such side effects are not common, meaning these were experienced by less than 10 dogs out of 1000. Regardless, if your dog experiences any of these side effects, contact your veterinarian immediately.


There are two primary ingredients in Nexgard Spectra that work to eliminate ticks, fleas, and a variety of worms from dogs. One of them is Afoxolaner which is an insecticide that targets fleas and ticks. This active ingredient in Nexgard Spectra kills fleas and ticks only when they bite your dog.

The other main ingredient is Milbemycin oxime which specifically targets internal parasites. This second ingredient is what makes Nexgard Spectra so effective against heartworms, lungworms, and gastrointestinal worms.
