Contraceptive patch

Definition: The contraception patch is meant for prevention of pregnancy. It is a transdermal patch that should be worn on skin and works by releasing synthetic hormones such as estrogen and progestin.
Provided that it is used properly, the contraception patch is very reliable; however it can not protect you from getting sexually transmitted diseases.
How it works: The patch works in a similar way like the contraceptive pill by releasing everyday a dose of female hormones such as estrogen and progestin which will migrate through the skin and into the bloodstream. Once they reach the bloodstream they will work like the natural hormones produced by your body and will prevent pregnancy by stopping the ovaries from releasing the ovule each month which could be then fertilized by sperm. In addition it will thicken the cervical mucus which will make it difficult for the sperm to reach the ovule. Also the lining of the womb will become thinner which will make it harder for the ovule to attach to the womb where it could be fertilized.
How to use it: The patch should be applied to a clean, dry and hair free area of your skin like stomach, buttocks, chest – except breasts, or the outside of your upper arm. The patch should not be rubbed by tight clothing and its position should vary each week it is changed.
After one week of wearing the patch, you should apply a new one on the same day of the week. This should be done for three weeks consecutive. On the fourth week you should stop using the patch. Usually during this week you will have your period which should start about four days after you take off the last patch. After a seven day break a new patch should be applied and this cycle should be repeated.
Advantages: The contraceptive patch is 99% effective if used properly.
It is very easy to use
It is very discreet
You can wear it anytime, anywhere, even while swimming, exercising or washing
You only have to remember to change it once a week, unlike the contraceptive pill which you have to remember to take everyday
The hormones from the patch reach the bloodstream directly; they do not need to be absorbed by the stomach unlike the contraceptive pill. Thus it will be effective even if you have indigestion.
It tends to make menstruation periods less painful and lighter.
Disadvantages:
It doesn’t protect from sexually transmitted diseases
In some cases it can cause skin irritation such as soreness or itching
Some mild side effects have been observed when first using the patch in some cases such as nausea, headaches, slight weight loss or gain, mood changes and breast tenderness. However the side effects settle down after a few months.
Bleeding between periods and irregular light bleeding have been observed in the first few cycles of patch use.
Some medicine can lessen the effectiveness of the patch, thus when prescribed new medicine you should tell your doctor that you are using the patch.
Risks:
There is a slightly increased chance of developing blood cloths which can block arteries or veins. This risk will be higher in overweight women or ones who had thrombosis or have a family member who had thrombosis.
Studies have shown that any form of hormonal contraception can increase the risk of developing breast cancer.
