EC/MAP has various names based on the manufacturer:

Plan B in the USA, Postinor-2 in Australia, etc.

Wilks: “Why this pharmacy does not sell Postinor-2; the 'morning-after' pill (MAP)

"1. Scientific studies have provided strong evidence indicating that for many women the 'morning-after' pill (MAP) does not stop a pregnancy from occurring.

"Researchers have said that it acts in at least 2 ways to end a pregnancy:   

"a.   By damaging the lining of the womb so that implantation of the human embryo - the unseen patient - cannot occur. [1]  

"b. Research in mice has also indicated that if an embryo attaches to the womb, the body reabsorbs it, thereby ending the embryo’s life. [2] 

"Because the MAP can act via these two methods, it must be classified as an abortifacient - a drug that can cause an abortion.[3]

"The fact that the MAP reduces the expected pregnancy rate by 87% supports the claim that it frequently acts to end the life of a human embryo. [4]  Therefore, due to the danger to the health of the human embryo caused by the MAP, my Code of Professional Conduct, parts 1.1 and 1.2,  forbids me from selling this drug.[5]

"2. The 'morning-after' pill is also very dangerous to a woman's health. Scientific reports have proved that:

* The 'morning-after' pill causes an increase in the incidence of ectopic pregnancies.[6]   In one of these cases the affected Fallopian tube had to be surgically removed. As a result these women have a greatly reduced possibility of a future pregnancy.

* The 'morning-after' pill can also have serious interactions with prescribed medications. The British Medical Journal has reported that the 'morning-after' pill can interfere with warfarin medications. [7] [8]

* Dr. Ellen Grant, writing in the Lancet (2001) has expressed the concern that ".5% of women have a genetic susceptibility to thrombo-embolic disease (blood clots)." When these women take the 'morning-after' pill - which is equal in strength to taking 50 regular birth control tablets - a blood clot might form. [9]

*  There is concern that the very high dose of hormone taken in the 'morning-after' pill might 'kick-start' cervical cancer if a woman is already infected with HPV.[10] Recent studies are showing the connection between HPV, chemical contraceptives, and cervical cancer.  

"In summary, because of these dangerous medical consequences associated with the 'morning-after' pill and my professional duty-of care responsibilities, we do not sell Postinor-2." [John Wilks B.Pharm., MPS, MACPP Consultant Pharmacist,18Feb04]
