Product information

Evra is a hormonal birth control patch made by Janssen. The active ingredients in the contraceptive are artificial hormones which temporarily alter the way the reproductive system functions. It is a transdermal patch, applied to the skin for seven days at a time, before it is replaced by a new patch, for three weeks. The fourth week of the menstrual cycle is patch-free, and the treatment is begun again the following week. Evra is also known as Ortho-Evra.

  1. Weekly applied patch 
  2. Just as effective as the pill
  3. Better for those who don’t like tablets

Each month, the female body goes through various phases to prepare itself to conceive. The process by which an egg is released by the ovary is referred to as ovulation, and this plays a key part in the start of pregnancy. Once the egg has been produced, it is fit to be fertilised by sperm.

What happens to the egg next depends on whether or not sperm makes successful contact. If it does, the impregnated egg moves along to the uterus and secures itself to the endometrium, before beginning its development into a baby. Otherwise, an unfertilised egg will simply reduce once it reaches the uterus and be excreted along with the endometrium, during menstruation.

The agents in Evra transdermal patch (also known as Ortho-Evra patch) are norelgestromin and ethinylestradiol, which mimic the activity of the hormones progesterone and oestrogen. In doing this, they prevent pregnancy in three ways, by: stopping the emergence of eggs from the ovary; managing the quality of the endometrium so that an egg cannot implant as easily; and increasing the density of vaginal fluid, so sperm cannot travel as freely.

Even though it is 99% effective, the hormonal pill isn’t for everyone. Some people prefer not to use treatment everyday, or might be even scared that they’ll forget to take their pill. The advantage of the Evra Patch is that it is only applied once a week. It works over seven days, after which it is replaced with a new one.

We know that getting access to the hormonal contraceptive you’re seeking can sometimes be a hassle. Arranging an appointment with your doctor, dropping your prescription off at the chemist and then having to return to pick your treatment up isn’t always convenient. That’s why we offer a combined consultation, prescription and dispensing service, so that you can get the product you need with just a few clicks.

Take our medical assessment. It only takes a few minutes to complete. A qualified practitioner will review your answers, to check whether the product you have ordered is suitable for you to use. If it is, your order will then be sent electronically to our pharmacy, who will prepare your items and send them to you by next-day tracked courier. All orders are delivered within one working day of successful consultation.

As with any type of contraceptive, it is vital to follow the instructions supplied so that your treatment is as reliable as possible. No form of hormonal birth control is guaranteed to prevent pregnancy, but applying the medication correctly will significantly increase its effectiveness.

  1. Each transdermal patch lasts for seven days. Apply it on the same day each week.
  2. After three weeks of application, do not use a patch for the fourth week.
  3. This constitutes a one-month cycle of treatment. Following this, apply the patch again and repeat the process.
  4. When putting on the patch, ensure you use an area of skin which is not irritated or in which the patch is likely to fall off. 
  5. The ideal areas for most tend to be the upper back, upper outer arm, buttock or abdomen.
  6. Make sure you press the patch down firmly for ten seconds when sticking it to the skin, and that the edges are sealed.
  7. Never use more than one patch at a time. 
  8. If you are starting the treatment for the first time or switching from another hormonal contraceptive, refer to the leaflet for specific instructions.
  9. For instructions on what to do if the patch falls off or you forget to put it on, consult the leaflet supplied or ask your doctor or family planning nurse.

The directions provided here are intended as a guide only. Please read those given with the product fully prior to use.
