Vaniqa

Vaniqa is a prescription cream applied to the skin for the reduction of unwanted facial hair in women ages 12 and older. However, for unknown reasons, Vaniqa does not work for everyone. A prescription is needed from the doctor and insurance policies do not cover Vaniqa.

Effectiveness: About 58% of women who tried Vaniqa in clinical trials had improvement. The other 42% had no improvement.

The medication simply retards hair growth to improve the condition and the appearance of some consumers. An individual will still need to continue using a hair removal method along with Vaniqa. It usually takes about two months of treatment before the results are obvious. If you stop taking Vaniqa, your hair may come back to previous levels within two months after stopping.

The active ingredient in Vaniqa is eflornithine hydrochloride, which inhibits an enzyme that affects hair growth, called ornithine decarboxylase ( ODC ).

Vaniqa should not be used:

* By men
* By women who are pregnant or nursing
* By females under age 12
* Anywhere except on the face and chin
* In the eyes, nose, mouth, or vagina
* If you have severe acne or broken skin

Vaniqa (pronounced “VAN-i-ka”) is a prescription cream applied to the skin for reducing unwanted facial hair in women ages 12 and older. For unknown reasons, Vaniqa does not work for everyone, and some insurance policies do not cover it.

This medication is not a depilatory, but rather appears to retard hair growth to improve the condition and the appearance of some consumers. You will probably need to continue using a hair-removal method (e.g., shaving, plucking) with Vaniqa. It usually takes 2 months to judge whether or not it is working. If you stop taking it, your hair may come back to previous levels within 2 months after stopping.

Vaniqa should not be used:

* By men. It has not been tested on men.
* By women who are pregnant or nursing. Vaniqa has not been tested to see if whether causes birth defects and miscarriages in humans.
* By females under age 12.
* Anywhere except on the face and chin. It has not been tested elsewhere.
* In the eyes, nose, mouth, or vagina.
* If you have severe acne or broken skin.

Background

Hair growth cells and cancer cells share some interesting characteristics: rapidly dividing with multiple potentials for differentiation. This is one reason chemotherapy and radiation can result in hair loss: they disrupt the same kinds of cellular activity. It has been theorized that some cancer drugs may be used to induce a controlled amount of hair loss or reduction. Vaniqa's active ingredient, eflornithine hydrochloride, has antitumor activity. It is the first commercially available topical preparation to come out of this sort of research.

Vaniqa became available in the U.S. on July 31, 2000, and is made by Bristol-Myers Squibb in a partnership with Gillette.

Clinical data

Eflornithine hydrochloride inhibits an enzyme that affects hair growth in rats. Regulation of this enzyme, called ornithine decarboxylase (ODC), was later shown to reduce hair growth in mice and sheep . Recent studies suggest that observations in certain types of mice may have parallels in humans .

This drug has been found to be an astonishingly effective cure for some types of African "sleeping sickness," even able to cause a rapid and complete recovery in comatose patients. Clinical reports show that taking it orally to treat sleeping sickness can induce hair loss as a side effect.

One large published study on safety found the product rarely caused significant side effects such as acne, follicle irritation, itching, or dryness. This corroborates unpublished data submitted to FDA showing that about 2% of subjects discontinued use due to adverse reactions.

Unpublished data submitted to FDA observed about 58% of women using it on facial hair had improvement. This study suggests it may be particularly effective in postmenopausal women.

Proof of how hard it is to judge effectiveness

Perhaps the most striking result was how many women in the control group (who used cream with no active ingredient) were observed to have less hair. Of 201 patients, over one-third who used a placebo were assessed by physicians as either "improved" or "marked improvement." This huge number of "false positives" means two things for consumers seeking hair removal:

* It's really hard to tell if a new hair removal product is effective or not, especially based on the personal experiences of just a few people.
* It's really easy for quacks to exploit this difficulty and make overblown claims about products they promote.

That's why you should rely on large-scale controlled studies to determine wheyher a hair-removal product is effective.
