Contraceptive counselling often features in OSCEs and therefore it’s important to be familiar with the various types of contraception available. This article focuses on counselling patients regarding the progesterone only pill (POP) including the common questions patients ask, the answers you’ll be expected to articulate and how best to structure the consultation overall.

Check out the POP counselling OSCE mark scheme here

 


Opening the consultation

  • Introduce yourself
  • Check the patient’s details (name/date of birth)
  • Check the patient’s understanding of the types of contraception available
  • Explore the reasons why the patient wants the progesterone only pill

 


Patient’s ideas, concerns and expectations

It is important to explore the patient’s ideas, concerns and expectations early in the consultation, as you may need to correct any misconceptions about the progesterone only pill and address any of the patient’s concerns.

When exploring concerns, it is important to do so in a sensitive and honest manner.

It’s also important to clarify the patient’s expectations of the POP, because if these are unrealistic, other forms of contraception may be better able to meet their needs.

 


What is the Progesterone Only Pill?

Ensuring to use patient-friendly language, explain that the progesterone only pill contain a progesterone hormone. Explain that different POPs contain different types of progesterone.

“The progesterone only pill, sometimes called the mini pill, is a type of contraceptive pill that contains a progesterone hormone. This hormone is almost exactly the same as the natural hormone that is produced by your ovaries.” ¹

 


What are the different types of POP?

You can explain to the patient that there are three main types of POP in the UK, and these depend on the type of progesterone in the pill.

  • Norethisterone
  • Levonorgestrel
  • Desogestrel

Levonorgestrel can be used as emergency contraception.

 


How does the Progesterone Only Pill work?

Explain to the patient the POP prevents conception by inhibiting ovulation, thickening cervical mucus, and thinning the endometrium to prevent implantation of the blastocyst. ²

“The main action of desogestrel is that it stops you from getting pregnant by stopping your ovaries from producing an egg every month. Other types of POP will sometimes stop you from producing an egg”

“All POPs also work by thickening the mucus around your cervix which stops sperm from entering your womb.”

“All POPs can also make the lining of your womb thinner which would prevent a fertilised egg from being accepted.”

 


How effective is the Progesterone Only Pill?

Patients understandably want to know how effective contraception is and this is often a major factor in their decision as to which type of contraception they want to use. As a result, it’s useful to know some basic statistics on efficacy. However, if you’re unsure, signpost the patient to a reliable source and don’t guess!

Explain to the patient that the effectiveness of the pill depends on compliance. However, if the POP is used according to the instructions given, it is 99% effective. ¹

  • “If you take the progesterone only pill at the appropriate time each day and don’t miss pills, it is 99% effective at preventing pregnancy.”

 


Pros and cons of the Progesterone Only Pill

Always give patients as much information as possible so that they can make an informed decision. It is useful to do this by discussing the pros and cons of the POP.

“If it is okay with you, I’d like to tell you about the benefits and disadvantages of the pill, then hopefully you will have enough information to make a decision”

Advantages of the POP

Non-invasive method

Ovarian cysts

  • “Sometimes women who use the POP may develop some small cysts on their ovaries.”
  • “These cysts are not dangerous and often disappear without any treatment.”

Contraindications of the POP ²

A patient should not take the pill if they:

  • Are pregnant
  • Have breast cancer
  • Have severe cirrhosis
  • Have liver tumours

 


Starting the pill and missed pills

This section of the consultation can be quite confusing for the patient (and sometimes the doctor!). It is therefore important to explain this in a patient-friendly manner, check understanding at regular intervals and invite questions at the end.

 

Starting the pill

  • “You can start the pill at any time if you are sure you are not pregnant. You will need to use condoms for the first seven days of taking the pill.” ¹

 

Missed pills

If one pill is missed or a new pack is started more than three hours* late ¹

  • “Take the missed pill straight away, if you have missed more than one pill, only take one pill.”
  • “Take the next pill at the usual time you would take it, this might mean you have to take two pills in one day. Don’t worry, this is not harmful.”
  • “Unfortunately, you are not protected from pregnancy and therefore you should use condoms for the next two days. Continue to take your pills as you normally would.”
  • “If you have had sex in the time you have missed your pill, you may need to seek advice for emergency contraception.”

 

If one pill is missed less than three hours* late

  • “Take the pill as soon as you remember to take it and then take your next pill at the usual time you would take it. You will be protected from pregnancy.”
  • *12 hours if it is the desogestrel progesterone only pill

 


Closing the consultation

  • Ask the patient if they have any further questions or concerns that haven’t been addressed.
  • Throughout the consultation you should check the patient’s understanding at regular intervals, using phrases such as “Can you just repeat back to me what we’ve just discussed regarding…”.
  • It may also be useful to quickly summarise what you have spoken about and direct the patient to any websites or leaflets with further information.
  • Make it clear that it is entirely the patient’s choice on what contraception she would like, and offer her time to think about her decision.
  • Encourage the patient to use condoms if is she is currently not using any contraception and is sexually active.
  • Thank the patient for her time.

 


Common patient questions

Below are some common questions that patients may have regarding the progesterone only pill. Sometimes, in an OSCE situation, they may ask you one or two questions at the end of your consultation. Having a good answer can be useful in demonstrating to the examiner that you have a solid understanding of the topic.

What happens if the patient is sick or have diarrhoea?

  • If the patient is sick within two hours of taking the pill then they will need to take another one if they are feeling better.
  • If a patient has severe diarrhoea for more than 24 hours, they will need to take the pill as if they missed a pill and follow the instructions. This should be until the diarrhoea is no longer severe.

 

Which common medicines affect the efficacy of the pill?

Explain to the patient that they should tell you or another health professional prescribing the pill what medicines they are currently taking.

“Some medicines such as some epilepsy medication, HIV medication and St John’s Wort can reduce the levels of contraceptive hormones and therefore reduce the effectiveness of the contraception.”

 

What should the patient do if they want to try and become pregnant?

Patients are usually advised to stop taking the pill at the end of a pack and wait until after their first natural period before trying to become pregnant. Don’t forget to advise the patient on pre-pregnancy care such as folic acid and quitting smoking.

 

What should the patient do if they want to stop taking the pill?

Patients are usually advised to stop taking the pill at the end of a pack. However, if they cannot wait, it is important to offer information about other contraception to prevent pregnancy.

 

Can the patient take the POP after having a baby?

Patient’s can take the POP from any time after birth. If the POP is started after day 21, advise them to use condoms for two days.
