A birth control patch is an effective contraceptive patch applied to the skin to prevent pregnancy. It employs transdermal patches to help prevent pregnancy by releasing a daily dose of estrogen and progestin hormones into the body. However, these birth control patches do not protect you against sexually transmitted infections (STIs) and are only accessible with a doctor’s prescription.
Read on to learn about the benefits and drawbacks of using birth control patches, directions for use, and answers to other frequently asked questions.
How Does A Birth Control Patch Work?
A birth control patch releases a daily dose of hormones into the bloodstream through the skin.
This contains hormones estrogen and progesterone, which prevent ovulation (release of the egg) each month to prevent pregnancy.
In addition to this, these hormones cause the thickening of cervical mucus, making it difficult for the sperm to move. The patch may also make the uterine lining thin, making it less likely to implant in the uterus even though the egg is fertilized (1).
The patch works the same way as a combined contraceptive pill to prevent pregnancy. It only differs in the mode of administration and the daily dose of the hormones.
How To Use A Birth Control Patch?
According to the American College of Obstetricians and Gynecologists, contraceptive skin patches can be worn on the arm, upper back, abdomen, buttocks, or chest (except the breasts). You may wear patches for three weeks (21 days) in a row, and one patch can be worn for a week (2).
Skip wearing the patch on the fourth week, and you will have your menstruation. To continue contraception on the next cycle, you may apply a new patch on the same day of the next week. It is recommended to use a patch on the same day of next week, even if you are bleeding.
Effectiveness Of A Birth Control Patch
Birth control patches are considered more than 99% effective in preventing pregnancy if used correctly. However, many women may make mistakes in using birth control patches, reducing their effectiveness to about 91%. This means that nine in 100 patch users can become pregnant each year (3).
Patches are more effective if you use them as recommended. Although the chance of getting pregnant while using a patch depends on how you use it, women who use it correctly have a low risk of getting pregnant.
The following tips may help you to ensure the effectiveness of the birth control patch (1).
- Stick the patch tightly to the skin
- Avoid sticking the patch onto an area of tight clothing where it may get dislodged
- Do not reuse patch that is not sticking or not all part of the patch is sticking on the skin
- Do not stick a non-sticky patch to the skin with tapes or other materials
- Check your patch regularly to ensure the edges are stuck to the skin
Some medications such as rifampicin (antibiotic), griseofulvin (antifungal), certain HIV medications, anti-seizure medications, and some herbs, such as St. John’s wort, could make the patch less effective. You should always inform your doctor that you are on the patch while getting prescriptions so that he/she can advise you if there are interactions. It is recommended to use condoms as a backup method to prevent pregnancy if you take medications that lower the patch’s effects.
Advantages Of A Birth Control Patch
Birth control patches are one of the simple and safe ways to prevent pregnancy. It is a more convenient form of birth control for many women than barrier contraceptives or daily pills. Women can become pregnant right away when they stop using birth control patches.
Other advantages of birth control patches may include the following (4).
- Effectively prevent pregnancy when it is used correctly. You may use birth control reminder apps to stay on schedule with applying the patches.
- Possible to use barrier contraceptives, such as condoms, along with birth control patches to prevent STDs.
- No need to take daily pills or emergency pills after intercourse to prevent pregnancy.
- The patch could make the periods regular, predictable and lighter.
- Hormones in the patch may reduce menstrual cramps in some women.
- The patch may lessen the risk of, or prevent health conditions such as, acne, premenstrual syndrome (PMS), ovarian and endometrial cancers, breast and ovarian cysts, anemia, and iron deficiency in some women.
There is no delay in return of fertility for birth control patches. Once you stop using the patch, your normal menstrual cycle returns and you can try to conceive.
Side Effects Of A Birth Control Patch
Although many women may not develop any side effects, hormones released from the birth control patches can cause certain effects in some women. Common side effects of the birth control patch may include (5):
- Skin irritation
- Breast pain and breast tenderness
- Heavy vaginal bleeding or spotting – breakthrough bleeding may be common in the first few cycles of the patch
- Vaginal discharges and infection
- Menstrual cramps
- Fluid retention
- Mood swings
Some of these side effects do improve after you have been on the patch for a few months.
Birth control patches may also increase the risk of high blood pressure, gallbladder disease, liver cancer, blood-clotting issues, stroke, and heart attack in some women. Some studies show that the risk for estrogen-related adverse events, such as blood clots in the legs/heart/lungs/brain, is more in patch users than those who use combination birth control pills. This can be due to higher estrogen levels in the body from patches than oral pills.
Other disadvantages of the birth control patches may include the following (1).
- Do not protect against sexually transmitted infections (STIs)
- Some medications can reduce the effectiveness of the patch
- You need to remember to change it every week
- Visible on the skin, making it a cosmetic concern for some women
Contraceptives, such as intrauterine devices (IUD) or implants, can be considered if you often forget to change the patch every week. However, if you want to protect yourself from STIs, condoms are the best method. Combined use of condoms and patches can provide you effective prevention of pregnancy along with protection from STIs.

All hormonal contraceptives containing estrogens, such as birth control pills, rings, and patches, are not recommended for women who are obese with BMI ≥35 kg/m2 and/or smokers and are 35 years or older.
