Post Highlights

The 'Morning after Pill' is frequently referred to as emergency contraception (EC). It is used to prevent pregnancy after unprotected sex. This pill prevents pregnancy by delaying the ovulation cycle and does not induce abortion. These pills are recommended to take sooner after sexual intercourse for better efficacy.

The 4 methods of emergency contraception include- ECPs with Ulipristal acetate (UPA), ECPs with Levonorgestrel (LNG), combined oral contraceptives, and copper-bearing intrauterine devices (IUD). 

Here we will describe how to get the morning-after pill for free.

How Does EC Work?

The 'Morning after' pill works by temporarily delaying or stopping egg release from the ovary. It might also prevent sperm from reaching the egg released from the ovary, thereby delaying ovulation. 

However, it should be noted that this pill doesn't work against Sexually Transmitted Diseases (STDs) nor in cases when fertilisation has already occurred.

Are These Pills Effective?

Morning after pill contraceptive pill is most effective if taken within the first  72 hours (3 days) after having unprotected sex, and it shows around 89% of effectiveness in plan B (Morning after pill) if you take it within a day. Pills can be taken up to 5 days after intercourse, but the sooner you take them after sex, the more effective. It is estimated to prevent 85% of pregnancies that would otherwise have occurred. Approximately 25% of women aged between 15 and 44, who currently use contraception, reported using the pill as their method of choice.

List Of Birth Control Pills

Most commercially oral contraceptives contain combinations of progestin and estrogen with varying doses in each brand. 

These pills come in a 28-pack, of which most drugs in each cycle are active, i.e., contain hormones, and the remaining drugs are inactive, i.e., they don't contain hormones. Several combination pills include -

  • Monophasic contraceptive pills - are used in 1-month cycles and provide the same dose of estrogen and progestin. During the last week of the period cycle, you can take (or skip) the inactive pills and still have menses. These are more preferred over multiphasic contraceptive pills due to ease of use and the same hormonal levels. Additional benefits include -

Improves bone health and density

Risk related to uterine and ovarian cancer is reduced.

  • Multiphasic contraceptive pills - are used in 1-month cycles and provide varying levels of estrogen and progestin. You can take or skip the inactive pills during the last week of the process and still have menses.
  • Extended-cycle contraceptive pills - used in 13-week cycles. Active pills can be taken for 12 weeks, and during the last week of the process, you can accept or skip the inactive pills and have your period. As a result, you have your period only three to four times per year.
ECPs are readily available over the counter at most pharmacies without any prescription. Only one type of pill, i.e., ECP with Ulipristal acetate (ella®), is available by prescription.
ECPs with Ulipristal acetate (UPA) should be taken only once in your cycle. At the same time, you can use ECPs with Levonorgestrel (LNG) more than once.
Any girl or woman who has attained the reproductive age might require emergency contraceptives to avoid unwanted pregnancy.

The morning after pill is free from the pharmacy

In some areas, getting the morning after pill from the pharmacy as part of a local NHS service is possible without seeing GP.

With many pharmacies opening late and quickly accessible, getting the morning after pill free from the pharmacy can be a good option. Patients need to note, however, that:

  • Not all pharmacies provide the morning-after drug for free
  • Those providing free emergency contraception services require a trained pharmacist to be present at the premises. Therefore, when free service may not be available, specifications for free emergency contraception service may differ depending on the pharmacy's location. As part of this NHS service Levonelle (or ellaOne in some areas) may be offered to all patients aged 16+, and patients under 16 years of age (Fraser competent)

Finding your local pharmacy and contacting them directly to see if free service for the morning after pill is offered would be the best course of action.

Both Levonelle and ellaOne can be purchased from most pharmacies (including large chain pharmacies such as Boots, Lloyds and Tesco) after consultation with the pharmacist. Levonelle is licensed from 16, whereas ellaOne has no age restrictions. To read more about emergency contraception, visit the NHS website.
