Because Frontline Plus is a topical insecticide, it is not required to have an expiration date. Depending on how old it is, it may not be effective for four weeks.
I cannot find an expiration date printed anywhere on the packaging. However, the Rx label from the vet clinic does state an expiration date (over 2 years from time of purchase).
Yes, all flea and tick medications have an expiration date. You'll need to check the outer box or the inner foil packet for the date. If you purchased the product more than a year ago, it will most likely be expired.

Incorrect. Frontline products do not carry an expiration date and will be effective indefinitely if stored at proper temperatures. add a comment
Frontline for dogs if purchased at a vet's office or in a pet store, the box as well as the individual pipettes do list a expiration date. Do not give the dogs whats in an unknown or expired vial.
