Eflornithine is an enzyme-inhibiting medication applied topically to reduce the growth of unwanted facial hair.
Eflornithine belongs to a small group of medicines called ornithine-decarboxylase inhibitors. It works by slowing the production of a protein that helps cells grow. In everyday use, eflornithine is best known for its ability to reduce the rate at which unwanted facial hair appears. The active ingredient is found in products such as Vaniqa and the injectable medicine simply named Eflornithine.
In Hong Kong, eflornithine appears in two main formulations:
Both products are regulated by the Hong Kong Department of Health and must be prescribed by a registered practitioner.
Eflornithine cream slows the growth of fine, unwanted hair on the face, especially in women who find shaving or waxing inconvenient. It does not remove existing hair but makes the hairs grow more slowly and appear finer.
The injectable form of eflornithine is one of the few medicines able to treat the second stage of this parasitic infection. It helps to clear the parasite from the central nervous system, a critical step in curing the disease.
These are the primary approved uses in Hong Kong. Doctors may occasionally consider eflornithine for other dermatological conditions, but such decisions are made on an individual basis.
Eflornithine blocks an enzyme that cells need to make certain proteins involved in hair-shaft formation and parasite replication. By inhibiting this enzyme, the drug reduces the speed at which hair follicles produce new hairs and, in the case of the injectable form, hampers the parasite’s ability to multiply. Effects on the skin usually become noticeable after several weeks of regular application, while the therapeutic impact on infection depends on the dosing schedule set by the treating physician.
These reactions are generally short-lasting and resolve without medical intervention.
If any of these occur, seek emergency medical care promptly.

Store the cream at room temperature, away from direct sunlight and moisture. Keep the injectable vials sealed until use and follow the hospital’s storage guidelines. Treatment duration varies: Vaniqa is usually applied twice daily for several weeks to see a change, while the injectable regimen follows a short-term course defined by the treating doctor. Always read the label that comes with your medication and follow the instructions given by your healthcare professional.
