Everything you need to know about Sandrena Gel

Sandrena is a transdermal oestrogen gel used as part of Hormone Replacement Therapy (HRT) to help relieve menopause symptoms. It contains estradiol, a form of oestrogen identical to the one your body naturally produces.

By applying Sandrena directly to the skin, the oestrogen is absorbed into the bloodstream without passing through the digestive system, making it a gentler option for women who experience stomach sensitivity with oral HRT and avoids risks associated with oral HRT.
