Daily Combined Hormonal Contraceptive Pill
How does it work?
The hormones prevent ovulation so there are no eggs (ova) released from the ovaries. It also changes the mucus of the cervix, making it harder for any sperm to enter the uterus. This prevents pregnancy.
Each individual pill contains a small mixture of progestogen and oestrogen hormones, and the amount and type of each hormone differs depending on the brand and design. There are over 30 brands of daily combined contraceptive pills available in Australia. Most packets have 28 pills, but some only have 21 pills.
You will still need to consider the risk of Sexually Transmitted Infections (STIs) every time you have sex.
What’s it like to use?
Most people find the pill easy to swallow as it is smaller than other tablets and multivitamins.
After 21 - 24 days of taking hormonal pills, you will either take a 4 - 7 day break without pills or you will take 4 - 7 of non-hormonal (sugar) pills. During that time you will experience a uterine bleed, which is similar to a menstrual bleed but is usually lighter.
Most pills are monophasic, meaning that each pill has the same amount of progestogen and oestrogen hormone. Other brands are triphasic, meaning that the amount of hormones may differ each week.
Continuous cycling is possible if your pill brand is monophasic. Continuous cycling involves using 3 packets of hormonal or active pills in a row without a break, or taking the sugar pills. It means you experience uterine bleeds less often. Before you experiment with continuous cycling, discuss it during an appointment with a reproductive and sexual health clinician or your local doctor.
What if I forget about it?
To be effective you need to remember to take the pill regularly every day.
- If you took the last pill within the past 48 hours (if it is up to 24 hours late): take the missed pill immediately. Your contraception will continue working.
- If you took the last pill more than 48 hours ago (if it is more than 24 hours late): take two pills, and then continue taking the pills as normal. You will need to use an alternative contraception method for 7 days. If you have had unprotected penis in vagina (PIV) sex, you may need to consider emergency contraception.
Who can use it?
People with a vagina and uterus of any age, from the first period to menopause.
The pill needs to be taken daily. If you are someone who is likely to forget, or if you do not have regular routine, consider a different contraceptive method.
It is suitable for people who have never experienced pregnancy and for use as contraception after pregnancy.
The pill should not be used if you have a history of migraines with aura or are at a high risk of blood clots. Migraines with aura, is a specific type of headache that should be excluded by a clinician. Your risk of blood clots will be evaluated by a clinician.
Contraceptives that contain oestrogen may be less suitable if you have a Body Mass Index (BMI) above 30. Consider progestogen only or non-hormonal contraceptive options.
If you experience polycystic ovarian syndrome (PCOS), the Combined Contraceptive Pill is generally considered to be the best contraceptive option. However, it is best to discuss your exact situation with a doctor.
If you are over 40 years old, contraceptives that contain oestrogen are less suitable, especially if you have other medical conditions. The combined contraceptive pill should generally not be used by people beyond the age of 50 years old.
It is suitable for people who may have a family history of breast cancer. It is generally not suitable for people who have experienced breast cancer in the past.
Side effects
It may take some time for your body to adjust to the hormones. Some people try a few different versions of the daily combined contraceptive pill before they find the dosage and type of hormone that is most suitable.
Side effects can include increased headaches, nausea, breast tenderness, bloating, and uterine spotting. You may find that you experience less hormonal mood changes and that your acne decreases. While body weight can change alongside hormonal changes, there is no reliable medical evidence linking contraceptive pills with weight gain.
A serious, but rare, risk of taking the daily combined contraceptive pill is blood clots. Blood clots may form in the calf, lungs or brain causing severe sudden chest pain, shortness of breath, severe pain or swelling in one leg, sudden blurred vision or loss of sight, or sudden severe headache. If you have any of these symptoms contact your doctor or go to your nearest emergency department immediately.
