Solve your dogs flea problems and prevent future flea infestations with Comfortis chewable tablets!

What is Comfortis? Comfortis is a beef-flavored chewable tablet that is given once a month. It works to kill fleas and to prevent and treat flea infestations in dogs.

Formulated for: Dogs and puppies over 14 weeks of age can receive Comfortis.

How is this medication given? Comfortis is an oral medication. Since it is flavored and chewable, most dogs take it easily.

Give this medication with food if possible. You should give another full dose of Comfortis if vomiting happens to occur within one hour of administration.

Giving Comfortis one month before active flea season starts will help to achieve optimal results. Once fleas become active, it is advised to continue this medication monthly until flea season ends. In regions where fleas are active year-round, this medication may be required monthly every month of the year to ensureadequate flea control.

Comfortis is available in multiple sizes and your dogs dose will be determined by his/her body weight. If your dog exceeds 120 lbs, you will need to give a combination of the appropriate sizes of medication in order to achieve the best results.

This medication can be prescribed for your dog by your veterinarian. You should give Comfortis only to the pet that it is prescribed for.

How does this medication work? Spinosad is the active ingredient in Comfortis. It works to excite the fleas nervous system which causes paralysis. This results in the death of fleas.

What results can I expect? Once Comfortis is administered, fleas should start to die within 30 minutes. Each dose remains effective for one month (30 days).

If Comfortis is given to your dog and he/she is infested with fleas, it is possible for fleas to linger beyond 30 days. This is because immature fleas in the environment still have the opportunity to hatch.

Comfortis is one key part of a good flea prevention program. Speak with your veterinarian about other precautions you can take to rid your dog of fleas and to prevent future infestations.

What Form(s) does Comfortis come in? This medication is available as a chewable tablet with beef flavoring. Different strengths are available ranging from 140 mg (5-10 lbs) to 1620 mg (60.1-120 lbs). The dose of medication your dog requires is based on his/her body weight.

Generic Name: Spinosad (Common Drug Name)

Common Brand Name: Comfortis (Lilly)

Dose and Administration: Comfortis is generally given once a month but always follow your veterinarians directions. It is recommended to give Comfortis chewable tablets with food.

Comfortis chewable tablets may be chewed, offered in food, or administered directly in the mouth like other medications.

If your pet vomits his/her medication within 1 hour of administration, you can repeat the dose.

Ideally, it is recommended to start giving Comfortis one month before fleas become active. After that, this medication should be given monthly through the end of the flea season.

If fleas are common in your area year-round, continue Comfortis monthly all 12 months of the year.

If there are fleas in the home, all pets should be treated with appropriate flea medication. Fleas need to be on your dog for this medication to kill them. Talk to your vet about other strategies you can use to eliminate flea infestations from your home.

Only give this medication to the pet that your veterinarian prescribes it for. If you are unsure of how to use this medication correctly, contact your veterinarian.

Uses: Comfortis is used to kill fleas and to prevent flea infestations in dogs for a full month.
