Frequently Asked Questions About Our Over-the-Counter (OTC) Plan B Service

Q: Do you need an appointment?
A: No.

Q: How much does it cost?
A: Current price: $32.00 (subject to change without notice)
CASH ONLY. We do not accept checks or credit/debit cards for OTC Plan B!

Q: When should it be taken?
A: Immediately after purchase for best results, unless purchased to have on hand for a future time. Otherwise, Plan B is most effective within the first 72 hours (3 days) after unprotected sex, but may be taken up to 120 hours (5 days). Keep in mind that the later Plan B is taken, the less effective it becomes.
Also remember that OTC Plan B does NOT protect against sexually transmitted infections or disease. FREE condoms are available at CMFP by the dozen, just ask for a bag at the window.
