How it works

Blocks neurokinin-3 (NK3) and/or neurokinin-1 (NK1) receptors in the hypothalamus to interrupt the temperature-regulation pathway that triggers hot flashes and night sweats.

Vaginal lubricants are short-acting gels or liquids applied directly before sexual activity to reduce friction and discomfort. They work by coating the vaginal and vulvar surface, supplementing natural lubrication that declines with estrogen loss. Unlike moisturizers, which are used on a regular schedule to hydrate tissue over time, lubricants are used on demand at the time of intercourse. Common formulations include water-based (containing glycerin or hyaluronic acid), silicone-based (longer-lasting, not water-soluble), and oil-based products.
