Is there any medication to increase the appetite?

Only in the very ill: Appetite becomes normal as a previously healthy person overcomes an illness and recovers. Feeling well, being able to smell food aromas, having no nausea (nor other tummy symptoms), feeling happy, and socializing while eating, all lead to a better appetite. For those losing weight from cancer or aids, some take marijuana extracts or hormone supplements to maintain appetite and weight.

Cyproheptadine HCL: This is a medication that is used in small doses to augment appetite in some patients. It is not the primary use of the drug but a side effect that may help some by stimulating appetite.
