Nonoxynol cost without insurance
Cash prices for Nonoxynol without insurance vary widely by pharmacy, strength and quantity — the same prescription can cost very different amounts at two pharmacies in the same town. That is the problem a membership solves.
Nonoxynol is on Tab's covered $0 generic list. With an active Tab membership, every covered strength is $0 — not a percentage off, not a coupon that changes month to month — at participating pharmacies nationwide or through mail order. You do not need insurance, and Tab works whether or not you have a health plan.
Tab is a membership, not insurance. Covered medications require a prescription from a licensed clinician.
Nonoxynol dosage and administration
Directions For maximum protection against unwanted pregnancy, follow the enclosed directions exactly. Insert one applicatorful into the vagina prior to intercourse (see complete, illustrated directions on package insert). Each applicatorful is effective immediately and up to one hour after application. An additional applicatorful is required prior to each act of intercourse, regardless of time since last application.
