Barrier contraception

The male barrier contraceptive device is known as the condom, or mbber, and is widely available in most countries. The condom is a mbber or latex sheath, sometimes packaged with a lubricant and spermicide, which serves as a cover for the penis and a receptacle for semen. The method is very effective if the condom is of good quaUty, remains on, and is replaced for each subsequent intercourse. It was reported that 6 biUion condoms were used in 1990 (101). Usage appears to be increasing as adjunctive use with other methods of contraception for prevention of HIV or other sexually transmitted diseases. By rough estimate, condoms may have been used in more than 13 biUion acts of sexual intercourse that risked unwanted pregnancy, HIV, and/or other sexually transmitted diseases (101).

Oral, transdermal, and transvaginal contraceptives, as well as intrauterine devices and most barrier contraceptives, do not protect against sexually transmitted diseases. 

Since the use of combined oral contraceptives may decrease the use of selected barrier contraceptive methods that do protect against STDs (e.g., latex condoms), one of the most common risks associated with the use of oral contraceptives is the risk of acquiring an STD.8... 

As an alternative to hormonal contraceptives, several barrier contraceptive options are available for the prevention of pregnancy. While barrier contraceptives are associated with far fewer adverse effects compared with hormonal contraceptives, their efficacy is highly user-dependent. Overall, compared with both hormonal contraceptives and IUDs, barrier contraceptives are...

Day 1 was the first day of the stop week, i.e. the first day after completing the previous cycle (menstruation generally starts on day 2 or 3, dosing with the oral contraceptive starts on day 8). Sexually active subjects used double barrier contraception during cycles 1 and 2, and for 28 days after completing cycle 2. Subjects were advised to continue use of these measures for at least 28 days after completing cycle 2. Dropouts were not to be replaced. 

Miss EV is taking the combined oral contraceptive (COC) pill and should be advised to use additional contraception (with a barrier contraceptive) for three weeks when starting the course of oral oxytetracyclines. She should also be advised to start the next pack of COCs without taking a 7-day break. After three weeks, additional precautions are not necessary as the bacterial flora (responsible for recycling ethinylestradiol from the large bowel) develop resistance.
