Comfortis Side Effects
The Scoop on Your Dog’s Flea Pill
The thought of instant flea removal is extremely appealing, but can Comfortis do what it claims without making your pet ill?
That’s what we’re going to find out over the next few paragraphs.
The active ingredient in Comfortis is Spinosad, an environmentally-friendly neurotoxin that kills fleas by exciting their nervous systems, causing paralysis and death.
What Are the Side Effects of Comfortis For Dogs?
First and foremost, you should know that the FDA has received reports of adverse effects in dogs who take spinosad and that are also taking high, extra-label dosages of ivermectin. That’s an insecticide found in Hartgard Plus, Iverhart Plus and regular Heartguard, among others.
Side effects are fairly uncommon with spinosad but include:
- Vomiting – this is the most common by far
- Increased appetite
- Excess vocalization
- Hives or red skin
If your dog experiences any of these side effects, stop use and contact your vet immediately.
Can Comfortis safely Kill Fleas On Dogs?
In the overwhelming majority of cases, yes this product is a safe, effective way to help keep your pet flea-free. Don’t use if you’re also using a product with ivermectin in order to avoid drug interactions. Also, to reduce the chances of nausea and vomiting, administer with food and if he does vomit within a few minutes, give him another full dose.
