(Consultation) NHS Progesterone Only Pill (Mini-Pill) **FREE**

Progesterone-Only Pill (POP): An Overview

The Progesterone-Only Pill (POP), often referred to as the “mini-pill,” is a popular contraceptive option provided for free under the NHS. It contains only a single hormone, progestogen, unlike the Combined Oral Contraceptive Pill, which also contains estrogen. The POP is highly effective at preventing pregnancy when taken correctly and is suitable for individuals who cannot or prefer not to use estrogen-containing contraceptives.

How Does the POP Work?

The Progesterone-Only Pill works by:

• Thickening cervical mucus: This makes it difficult for sperm to reach and fertilize an egg.
• Thinning the uterine lining: Reducing the likelihood of implantation if fertilization does occur.
• Suppressing ovulation: Some POPs prevent the release of an egg in most cycles.

Unlike the combined pill, the POP is taken every day without a break.

Who is the POP Suitable For?

The POP is especially suitable for:

• Breastfeeding individuals (does not affect milk supply).
• Individuals who cannot take estrogen due to medical conditions (e.g., migraines with aura, high blood pressure, history of blood clots).
• Smokers aged over 35.

Types of Progesterone-Only Pills

There are two main types of POPs available, categorized by their primary active ingredient and duration of action:

1. Traditional POPs (3-Hour Pill)

These pills must be taken at the same time every day, with a strict 3-hour window. Missing a pill by more than 3 hours increases the risk of pregnancy.

Examples of 3-hour POPs:

• Norgeston (contains levonorgestrel)
• Noriday (contains norethisterone)

These pills primarily rely on thickening cervical mucus, and ovulation is not always suppressed.

2. Desogestrel POPs (12-Hour Pill)

These newer POPs offer greater flexibility, allowing a 12-hour window for missed pills. They are also more effective at consistently suppressing ovulation.

Examples of 12-hour POPs:

• Cerazette
• Cerelle
• Zelleta

Desogestrel POPs are often preferred due to their flexibility and higher efficacy.

How to Take the POP

• Take the pill at the same time every day.
• There are no pill-free breaks; all pills in the pack are active.
• If you miss a pill or take it outside the recommended time window, follow the instructions for missed pills and use additional contraception (e.g., condoms) if necessary.

Advantages of the POP

• Can be used by most individuals, including those with health risks associated with estrogen.
• Does not interrupt sex.
• Can be taken during breastfeeding.
• May reduce period pain and lighten or stop periods altogether.

Disadvantages of the POP

• Must be taken at the same time every day to maintain effectiveness.
• May cause irregular bleeding or spotting, especially in the first few months.
• Does not protect against sexually transmitted infections (STIs).

How to Access the POP

The POP is available free through:

• NHS GP surgeries.
• Sexual health clinics.
• NHS-approved online services.

If you’re considering the POP or unsure which type is best for you, book a consultation with your GP or a sexual health clinic to discuss your options.
