About this medicine

Clomipramine treats separation anxiety.

Products with this ingredient include Clomicalm. The FDA hides brand names in its public data, so these reports cover every product with the same active ingredients.

Questions owners ask

Can Clomipramine cause lethargy in cats?: 35 reports link the two, but a report alone does not prove the medicine was the cause: other illnesses, other medicines or coincidence can be involved. Your vet can judge it for your animal.
What should I do?: Don't give another dose until you've spoken to your vet, and keep the packaging so you can tell them the product and dose. Your vet can also report it to the FDA (or you can, through the manufacturer or FDA form 1932a).
