[edit] MECHANISM OF ACTION

Topical eflornithine, works by blocking the action of an enzyme called 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.

[edit] INDICATIONS

Topical Eflornithine 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.

[edit] DOSAGE

Topical Eflornithine is applied to clean and dry affected areas of the face and under the chin twice a day (at least eight hours apart). It is applied in a thin layer and rubbed in thoroughly. Improvements may be noticed within eight weeks of starting treatment. Continued treatment is needed to maintain the beneficial effects and may lead to further improvement. Topical Eflornithine should be stopped if no improvements are noticed within four months of starting treatment.

[edit] WARNINGS AND PRECAUTIONS

Excessive hair growth can result from serious underlying disorders (e.g. polycystic ovary syndrome, androgen secreting neoplasm) or certain active substances (e.g. cyclosporin, glucocorticoids, minoxidil, phenobarbitone, phenytoin, combined estrogen-androgen hormone replacement therapy). These factors should be considered in the overall medical treatment of patients who might be prescribed Eflornithine topical cream.
