Abstract
Women and couples continue to experience unintended pregnancies at high rates. In the US, 45% of all pregnancies are either mistimed or unwanted. Mishaps with contraceptives, such as condom breakage, missed pills, incorrect timing of patch or vaginal ring application, contraceptive nonuse, forced intercourse, and other circumstances, place women at risk of unintended pregnancy. There is a critical role for emergency contraception (EC) in preventing those pregnancies. There are currently three methods of EC available in the US. Levonorgestrel EC pills have been available with a prescription for over 15 years and over-the-counter since 2013. In 2010, ulipristal acetate EC pills became available with a prescription. Finally, the copper intrauterine device remains the most effective form of EC. Use of EC is increasing over time, due to wider availability and accessibility of EC methods. One strategy to expand access for both prescription and nonprescription EC products is to include pharmacies as a point of access and allow pharmacist prescribing. In eight states, pharmacists are able to prescribe and provide EC directly to women: levonorgestrel EC in eight states and ulipristal acetate in seven states. In addition to access with a prescription written by a pharmacist or other health care provider, levonorgestrel EC is available over-the-counter in pharmacies and grocery stores. Pharmacists play a critical role in access to EC in community pharmacies by ensuring product availability in the inventory, up-to-date knowledge, and comprehensive patient counseling. Looking to the future, there are opportunities to expand access to EC in pharmacies further by implementing legislation expanding the pharmacist scope of practice, ensuring third-party reimbursement for clinical services delivered by pharmacists, and including EC in pharmacy education and training.Entities:

Models of access to emergency contraception in the US
| Model | Description |
|---|---|
| Prescription only | Approved as a prescription drug by the FDA. |
| Pharmacist prescribing | Approved as a prescription drug by the FDA and available directly from a pharmacist without a prior prescription, either under a statewide authority or collaborative practice agreement with a prescriber. The pharmacist initiates the prescription, and can dispense the medication. This is a de facto category allowed by state laws, and not recognized by the FDA. Also known as pharmacist-initiated or pharmacy access. |
| Behind-the-counter | Approved as a nonprescription drug by the FDA, but has additional restrictions requiring oversight by the pharmacy, such as identification requirements or sex or age restrictions. This is a de facto category, and not recognized by the FDA. |
| Over-the-counter | Approved as a nonprescription drug by the FDA. |

Hawaii BOP staff state that the current EC protocol appendix is under review. Training: completion of an accredited training program that must include the following: |
| Maine | Yes | Yes | Pharmacists may initiate EC under state BOP regulation MRS 32-12-13821, with a written protocol agreement between a pharmacist and physician. The pharmacist must provide the patient with a state BOP-approved fact sheet. Training: completion of an accredited training program that must include the following: |

| New Hampshire | Yes | Yes | Pharmacists may initiate EC under a state BOP regulation, 318:16-a, with a written protocol agreement between a pharmacist and physician. This is a broad policy, which does not specifically include or exclude EC. Training: pharmacist-training requirements depend on the service provided, and must be included in the collaborative practice agreement between the prescriber and the pharmacist and approved by the state BOP. |
| New Mexico | Yes | No | A section of the current state BOP regulation, NMAC 16.19.26.10 of the Pharmacist Prescriptive Authority Act allows pharmacists to “issue a prescription for emergency contraceptives”. However, the protocol does not include UPA. New Mexico Board of Pharmacy staff state that a new hormonal contraception protocol is under review, which includes a proposal for UPA. Training: NA |
| Vermont | No | No | Notes: Previous state BOP regulations that allowed pharmacists to initiate EC, VSA 26.036.2077–2079, expired May 2015. Pharmacists are no longer permitted to initiate prescription-only EC under a protocol in this state. Training: NA |
| Washington | Yes | Yes | Pharmacists may initiate EC under state BOP regulation WAC 246-863-100, with a written protocol agreement between a pharmacist and physician.

Patient counseling points for EC
| • LNG is approved for use up to 72 hours after unprotected sex, but studies show effectiveness in pregnancy prevention up to 120 hours after sex. LNG EC is more effective the sooner it is taken. |
| • LNG EC does not prevent sexually transmitted diseases, does not affect an established pregnancy, and will not cause an abortion. It should not be used in an existing pregnancy. |
| • If your BMI is >25 kg/m2, the other EC methods may be more effective. |
| • Hormonal contraceptive methods may be started immediately after taking LNG EC, but you still need to use 7 days of a backup contraceptive method. |
| • Common side effects include menstrual changes, with possibilities of heavier or earlier menses, breast tenderness, nausea and vomiting, and headache. |
| • LNG EC is not 100% effective, and you should obtain a pregnancy test if you have not received your period after 3 weeks or your period is more than 1 week late. |
| • There are longer term options, such as hormonal contraception (pills, patch, vaginal ring, IUD) or a copper IUD, that may be more suitable forms of regular contraception. |
| • LNG EC will not cause adverse effects with repeated use. |
| • UPA EC may be taken up to 120 hours following unprotected intercourse, and should be taken as soon as possible. |
| • UPA EC does not prevent sexually transmitted diseases, does not affect an established pregnancy, and will not cause an abortion. It should not be used in an existing pregnancy. |
| • It may be less effective if your BMI is >30 kg/m2. |
| • Other hormonal contraceptives should not be used for 5 days after UPA EC use, due to a potential drug interaction that counteracts the effect of |
| UPA, and potentially renders it ineffective. |
| • Common side effects include menstrual cycle changes, headache, nausea, fatigue, and dizziness. |
| • UPA is not 100% effective, and you should obtain a pregnancy test if you have not received your period after 3 weeks or your period is more than 1 week late. |
| • There are other contraceptive options, such as hormonal methods (pills, patch, vaginal ring, IUD) or copper IUD that may be more suitable forms of regular contraception. |
| • UPA will not cause adverse effects with repeated use. |
| • If breastfeeding, breast milk should be discarded for 1 week following UPA use. |
| • Use of concurrent medications that induce CYP450 enzymes, such as St John’s wort, barbiturates, bosentan, rifampin, and certain migraine, seizure, and HIV medications, may also decrease the effectiveness of UPA. |
| • Copper IUDs are effective as EC immediately if inserted within 5 days of unprotected intercourse. The copper IUD also immediately prevents pregnancy from future acts of intercourse, and no backup method of contraception is needed. |
| • These devices do not prevent sexually transmitted diseases, do not affect an established pregnancy, and do not cause an abortion. They should not be used in an existing pregnancy. |
| • Copper IUDs are the most effective form of EC, and can be used for up to 12 years to prevent pregnancy. |
| • The device is placed in your uterus by a health care professional, and requires a clinic visit. |
| • The effectiveness of copper IUDs is not decreased by body weight, unlike EC pills. |
| • The most common adverse effects include abnormal menstrual bleeding and abdominal pain and/or cramping. |
| • Copper IUDs prevent pregnancy by affecting the ovum and sperm to prevent fertilization. |
| • Previous theories that IUDs can damage a fertilized ovum or prevent implantation are not supported by current evidence. |
| • Copper IUDs do not contain hormones. IUDs containing hormones are available, but not recommended for EC. |
