Contraceptive Patch Singapore
What is a Contraceptive Patch? - Contraceptive Patch Singapore
The Evra transdermal patch is a hormonal contraceptive in the form of a patch which is applied to the skin. It contains a combination of estrogen (Ethinylestradiol) and protegestogen (Norelgestromin). It is about 91% effective in preventing pregnancy (in contrast, condoms are 85% effective).
How does the Contraceptive Patch work?
The patch releases a daily dose of both hormones which is absorbed through the skin into the bloodstream and works to prevent pregnancy by 1) inhibiting ovulation/the release of an egg and 2) altering your body’s internal environment to make conditions unfavourable for fertilisation to occur.
The hormones released thicken the cervical mucus, making it more difficult for sperm to pass through the cervix into the womb, and thin the lining of the womb, making implantation of a fertilised egg unfavourable. - Contraceptive Patch Singapore
How does one use the Contraceptive Patch?
Each patch lasts a week. You use 3 patches in a row for a total of 3 weeks, then stop for a week, during which a withdrawal bleeding similar to a menstrual period may occur. After the patch-free week, you restart a new patch and the 4-week cycle repeats again.
The patch is applied directly to clean, dry skin. Most areas of the body are suitable: the buttocks, hips, abdomen, shoulders and upper back are possible areas you can apply the patch to. You should avoid areas where friction between clothing and skin may cause the patch to come loose, or areas with open wounds or irritated skin. Rotating the site of application is recommended in order to reduce the risk of skin irritation.
The patch is extremely sticky and you can shower, swim, exercise and continue with daily activities with it on.
If the patch is started on Day 1 of the menstrual cycle, it is immediately effective in conferring protection against pregnancy. However, if it is started anytime else during the menstrual cycle, barrier protection (condoms) should be used for the first 7 days.
Are you a suitable candidate for the Contraceptive Patch?
The safety and efficacy of Evra is well studied in women between 18-45 and is suitable for most women unless they have pre-existing medical conditions that preclude its use.
The hormonal components of the patch make it unsuitable for someone who may have:
- A risk of arterial or venous thromboembolism (blood clots in the arteries or veins)
- Including previous episodes of blood clots or a family history suggestive of being prone to clots
- BMI >30
- Specific medical conditions associated with clotting tendencies
- Age >35 and smoking
- Migraines with aura
- Known or suspected cancers of the breast, endometrium or estrogen dependent cancers
- Liver disease
- Individuals on certain specific medications e.g. certain medications for HIV or epilepsy
- Breastfeeding mothers
What are the pros and cons of the Contraceptive Patch?
- If used correctly, the patch is an effective and convenient form of birth control which allows sexual spontaneity and requires changing only once a week (as opposed to taking a daily pill)
- For women struggling with PMS or heavy, painful menses, the patch will help reduce these symptoms, resulting in a lighter and less painful period
- It may reduce the risk of ovarian and womb cancers
- Illnesses like diarrhoea and vomiting do not affect the hormones released by the patch (as opposed to the birth control pill)
- Potential skin irritation and discomfort
- Hormonal associated side effects (common to all hormonal forms of contraception) including spotting, nausea, breast tenderness, mood changes, many of which are mild and go away after the initial phase
- No protection against STDs

What is the difference between the Contraceptive Patch and other forms of birth control
(e.g. the combined oral contraceptive pill, depot injection, hormonal implant and IUD?)
The various types of contraception differ in terms of duration of efficacy, what they contain, which determines how they work to prevent pregnancy and their associated side effects.
|Combined oral contraceptive pill (Various brands)||Taken daily||Both estrogen and progestogen hormone|
|Evra patch||Changed weekly||Both estrogen and progestogen hormone|
|Depot injection (Depo Provera)||Every 12 weeks||Progestogen|
|Hormonal implant (Implanon)||Lasts 3 years||Progestogen|
|Intrauterine device (IUD)||Lasts between 3-10 years||Either progestogen or copper|
You may speak to a doctor to find out more about the various contraceptive methods and what may be most suitable for you.
Return to fertility after stopping the Contraceptive Patch
Upon stopping the patch, return of fertility is fairly rapid; in most people, their menstrual periods will return to normal within 1-2 months. This may occasionally take up to 6 months.
