Clear Start Assessment

Sandrena is a prescription-only hormone replacement therapy (HRT) gel used to relieve moderate to severe symptoms of the menopause in women with oestrogen deficiency. These symptoms may include hot flushes, night sweats, mood swings, low libido, fatigue, and vaginal dryness. Sandrena is often prescribed when symptoms negatively impact daily life and lifestyle measures alone are not sufficient. It is also used to prevent bone loss (osteoporosis) in postmenopausal women at increased risk of fractures who cannot take other osteoporosis treatments.

How It Works

Sandrena contains estradiol, a bioidentical version of the primary female sex hormone oestrogen. During the menopause, natural oestrogen production decreases significantly, which leads to a range of physical and emotional symptoms. Sandrena works by restoring systemic oestrogen levels through daily application of a measured gel to the skin. The estradiol is absorbed transdermally into the bloodstream, bypassing the digestive system. This helps reduce common menopausal symptoms and supports long-term hormonal balance. Because of its direct absorption through the skin, Sandrena provides consistent hormonal levels while reducing the risk of gastrointestinal side effects seen with oral HRT.

Why Choose Sandrena

Sandrena offers a flexible, well-tolerated method of hormone replacement therapy for women seeking relief from menopausal symptoms. The gel comes in pre-measured sachets (0.5 mg or 1 mg), allowing for easy dose adjustments based on individual needs. It is applied to the thighs or lower abdomen, dries quickly, and does not require ingestion—making it an ideal choice for women who prefer non-tablet HRT. Clinical guidance often favours transdermal HRT options like Sandrena due to their lower risk of clotting compared to oral treatments. In addition to symptomatic relief, Sandrena also supports bone density, reducing the long-term risk of osteoporosis and related fractures.

Important Note

This medication is not suitable for everyone and must be used under medical supervision. It is not a contraceptive and should not be used to prevent pregnancy. Women with an intact uterus should also take a progestogen to protect against endometrial hyperplasia. The gel should not be applied to broken, irritated, or mucosal skin. Treatment should be regularly reviewed to assess ongoing benefits and risks. Like all forms of HRT, Sandrena should be used at the lowest effective dose for the shortest necessary duration.
