Q

Which method of contraception would you ideally want to AVOID in the ff women:

19 year old with a positive diagnosis of Chlamydia and abdominal pain

A

Depot medroxyprogesterone acetate (DMPA)

The IUD may be inserted in women with a previous history of Chlamydia or pelvic inflammatory disease (PID) but it should not be inserted in the presence of acute or current infection. If this 19 year old has a positive diagnosis of chlamydia and is complaining of abdominal pain, PID should be ruled out and treated before inserting an IUD.

DMPA may result in a delay in return of fertility of up to a year, therefore you may wish to avoid this in a woman that is eager to start a family in the next 6 months. The COCP and IUD do not delay return of fertility.

Enzyme inducing drugs may increase the hepatic clearance of COCPs resulting in a reduced efficacy. They do not affect DMPA or the IUD.
