Vaniqa is used for the treatment of facial hirsutism in women. Facial hirsutism is excessive growth on the face of coarse hair, often in a male pattern.
The medicine can only be obtained with a prescription.
Vaniqa is applied in a thin layer to clean and dry affected areas twice daily (at least eight hours apart) and rubbed in. A benefit may be noticed within eight weeks of starting treatment. Continued treatment may give further improvement and is necessary to maintain beneficial effects. Vaniqa should be stopped if no beneficial effects are noticed within four months of starting treatment. Women using Vaniqa may still need to use other means to remove hair (plucking, shaving).
Vaniqa contains the active substance eflornithine. Eflornithine blocks the action of an enzyme, ornithine decarboxylase. This enzyme is found in the bulb of the hair follicle where it controls hair production. When this enzyme is blocked, the growth of hair is slowed down.
The effectiveness of Vaniqa has been studied in two clinical trials including 596 women treated for up to 24 weeks with Vaniqa, or with a placebo (a dummy treatment, in this case the cream without any active substance). The effectiveness of the treatment was assessed by the doctor at the end of the study who graded the hirsutism as: ?clear/almost clear?, ?marked improvement?, ?improved? or ?no improvement/worse?, 48 hours after women had shaved the treated areas of the face and under the chin.
Improvement was seen as early as 8 weeks after the start of treatment. Significant improvement for Vaniqa versus placebo was seen in both studies. When the results were combined, a successful outcome (graded as ?clear/almost clear? or ?marked improvement?) was seen in 35% of women treated with Vaniqa, against 9% of those treated with placebo.
The most common side effect (seen in more than 1 patient in 10) is acne. Other common side effects are pseudofolliculitis barbae (ingrown hairs), alopecia (hair loss), stinging skin, burning skin, dry skin, pruritus (itching), erythema (redness), tingling skin, irritated skin, rash, and folliculitis (infected hair follicles). For the full list of all the side effects reported with Vaniqa, please see the Package Leaflet. Vaniqa should not be used in people who may be hypersensitive (allergic) to eflornithine or to any of the other ingredients.
