Intrinsa indications

Intrinsa is a transdermal patch that helps women with sexual dysfunction get back their sexual desire and libido. It comes in the form of a thin, clear, oval patch and has the natural hormone testosterone as its active substance testosterone. Intrinsa works by constantly releasing small amounts of testosterone into the bloodstream through the skin.

Intrinsa works by releasing the male hormone testosterone through the skin into the bloodstream. Testosterone is naturally occurring in women, and is produced by the ovaries and the adrenal gland. However, levels of the hormone decline with age, sometimes dramatically so after the menopause or after a hysterectomy. Testosterone therapy is systemic and needs to be applied over a period of weeks or months to have a noticeable effect. P&G licensed the treatment to Watson Pharmaceuticals.

The amount of testosterone in the patch, 300µg/24hrs, is significantly lower than in testosterone patches for men. The patch is virtually transparent and about the size of an egg and is worn just below the navel and changed twice weekly.
