INTRODUCTIONINTRODUCTION• According to figures from the population Reference Bureau, there are 8300 million humans on the

planet.• There are 42 births and 17 deaths

every 10 seconds, a net gain of 25 extra people somewhere on the globe every 10 seconds.

Page 3: Overview of contraception

INTRODUCTIONINTRODUCTION

• According to UN figures, out of about 180 million conceptions each year, at least 75 million are unwanted.

• This results in about 50 million abortions.

• Around 600 000 women die each year (one woman/min)- killed by pregnancies.

• 200 000 would not die if adequate services/contraception make available to them

Transdermal Contraceptive Patch:Transdermal Contraceptive Patch:Patient Counseling on Usage and DisposalPatient Counseling on Usage and Disposal• Application:

– Use a new location for each patch– Apply to clean, dry skin– Apply where it won’t be rubbed by clothing: on buttocks,

abdomen, upper outer arm, upper torso– Do not use on irritated or abraded skin– Do not use on the breasts– Avoid oils, creams, or cosmetics until after patch placement– Bathe and swim as usual

• Anticipate more breast discomfort during the first 2 months

• Store at room temperature • Do not cut, alter or damage the patch as if may alter

contraceptive efficacy• Do not flush a used patch into the water system; fold

the used patch in half and place in the trash

Transdermal Contraceptive Patch:Transdermal Contraceptive Patch:Patient Counseling on Basic InstructionsPatient Counseling on Basic Instructions• If switching from an oral contraceptive, apply the

patch as soon as withdrawal bleeding begins (Day 1 Start)

- Sunday Start: use backup protection for 7 days unless Sunday is the first day of the menstrual cycle

• Wear each patch for 7 days; subsequent patch changes are made on the same day of the week

• No more than 7 days should lapse between the application of the last patch of the prior 21-day cycle and the first patch of the next 21-day cycle

• For partial or full detachment, make sure the exposed undersurface of the patch is clean and adherent; press it into place for 10 seconds; if the patch does not adhere completely, remove it and replace it with another patch
