What it is
Saheli is the brand name for ormeloxifene, also called centchroman. It is a non-steroidal selective estrogen receptor modulator developed by India’s Central Drug Research Institute (CSIR-CDRI). Indian regulators approved it for contraception in 1990, and it has been on the market there since 1991. It is the only non-hormonal oral contraceptive approved anywhere in the world.
How it works
Ormeloxifene prevents pregnancy by inhibiting implantation of a fertilized egg in the endometrium, the lining of the uterus. It does not suppress ovulation. It does not contain estrogen or progestin. It does not interfere with the hypothalamic-pituitary-ovarian axis, the hormonal feedback loop that combined pills act on.
Dosing
The standard schedule is one 30 mg tablet twice weekly for the first 12 weeks, then once weekly after that.
Efficacy
Phase III trials in India reported a method-failure Pearl Index of 1.83 to 4.2 per 100 woman-years, which corresponds to about 96% to 98% perfect-use efficacy. Actual-use failure rates including user error were higher, with a Pearl Index around 9 per 100 woman-years (about 91% typical-use efficacy). A 2025 real-world study of 148 women reported a Pearl Index of 2.1 with 88.5% compliance. All efficacy data comes from Indian studies. No US trials have been conducted.
Availability
Saheli is not FDA-approved and is not available in the United States. It is sold in India under the brand names Saheli, Saheli Plus, Novex, and Novex-DS by HLL Lifecare Limited, a Government of India enterprise. Since 2016, the Indian government has distributed it free of cost at public health facilities under the brand name Chhaya. Torrent Pharmaceuticals sells the same molecule as Sevista for dysfunctional uterine bleeding, a separate indication.
