All sexually-active women who have sex with men need to make decisions about which birth control method is best for them. If you are an HIV+ woman, your decision should take into account the possibility of passing the virus to your partner. This is true if your partner(s) is HIV+ or HIV-negative.

When both partners are HIV+, you do not need to worry about one getting infected with HIV. However, one partner could reinfect (also called superinfect) the other with a strain of HIV that is resistant to the HIV drugs being taken. Also, other sexually transmitted diseases (STDs) could be passed from one partner to the other. The only forms of birth control that will provide protection against HIV and other STDs are abstinence (not having sex) or using condoms while having sex.

Not all HIV+ women will want to, or be able to, have their partners use condoms, whether their partners are HIV+ or HIV-negative. For HIV+ women who do not use condoms and do not want to get pregnant, there are a number of other choices available. These other methods of birth control offer protection against pregnancy, but do not protect against HIV or other STDs.

Benefits:

• Female and male condoms are the most effective ways to prevent many STDs (including HIV)
• Up to 98 percent effective at preventing pregnancy if used correctly
• The female condom is the only female-controlled method of birth control that also provides protection from STDs
• Male condoms are inexpensive
• Do not require prescription

Drawbacks:

• Male condom requires cooperation of the male partner
• May break if not put on correctly or if used with oil-based lubricants like baby oil or Vaseline
• Must be put on immediately before sex while the male partner is erect
• Female condoms are expensive and not available everywhere

Hormone-based contraceptives are available in combined estrogen and progesterone (ethinyl estradiol/norethindrone) or progesterone-only formulations. Hormone methods are available in many different forms including pills, shots, implants, vaginal rings, patches, and IUDs.

Depending on which you choose, you will need to use hormone methods daily, weekly, monthly, or yearly. You need a prescription for hormone methods and in some cases a health care provider must administer them on a regular basis.

Benefits:

• Very effective (97 to 99 percent) in preventing pregnancy
• You do not need to do anything right before sex to prevent pregnancy
• May reduce risk of ovarian and endometrial cancers, pelvic inflammatory disease, non-cancerous growths of the breasts, ovarian cysts, and osteoporosis (thinning of the bones)
  

Drawbacks:

• Not effective against STDs (including HIV)
• Many possible side effects
• May increase risk for blood clots, heart attack, and stroke (especially among smokers age 35 and older)
  

Some hormone-based birth control methods can interact with HIV drugs, changing the level of one or more drugs in the blood stream. Some HIV drugs decrease the levels of hormone-based birth control, increasing the chances of an unwanted pregnancy. Some HIV drugs increase the levels of hormone-based birth control methods. It is not clear what affect this will have.

If your HIV drugs interact with the levels of your hormone-based birth control, you should speak to your health care provider about whether an alternative form of contraception should be used. The following HIV drugs may interact with hormone-based birth control:

• Aptivus (tipranavir) with Norvir (ritonavir)
• Kaletra (lopinavir/ritonavir)
• Prezista (darunavir) with Norvir
• Invirase (saqunavir) with Norvir
• Lexiva (fosamprenavir) with or without Norvir
• Reyataz (atazanavir) with or without Norvir
• Viracept (nelfinavir)
• Crixivan (indinavir)
• Viramune (nevirapine)
• Sustiva (efavirenz)
• Atripla (efavirenz + tenofovir + emtricitabine)

The diaphragm and cervical cap fit over the cervix. Both need to be fitted by a health care provider and used with a spermicide cream or jelly.

Benefits:

• Up to 94 percent effective in preventing pregnancy if used correctly
• Can be inserted ahead of time, so as not to interrupt sex
• There are usually no side effects
• Cannot usually be felt by either partner
  

Drawbacks:

• Does not offer protection against STDs (including HIV)
• May be difficult to insert

Spermicides are available in a variety of forms such as foam, jelly, cream and suppository.

Benefits:

• Inexpensive
• Does not require prescription
• Can be inserted ahead of time, so as not to interrupt sex
• There are usually no side effects
• Cannot usually be felt by either partner
  

Drawbacks:

• Not very effective when used alone as birth control
• Offer no protection against STDs (including HIV)
  
  

Warning: The spermicide Nonoxynol-9 (N-9) can actually increase HIV risk by irritating the skin in the vagina and rectum. It should not be used to try to prevent HIV transmission.

A surgical procedure that can be performed on a woman (tubal ligation) or a man (vasectomy). It is almost 100 percent effective against pregnancy; however it is not effective against STDs (including HIV).

Includes abstinence, withdrawal, and fertility awareness-based methods (Rhythm Method). The effectiveness of natural birth control options at preventing pregnancy ranges from 100 percent (abstinence) to 73 percent (withdrawal method). Except for abstinence, natural methods are not effective for preventing STDs (including HIV).

There are two methods to help prevent pregnancy after unprotected sex: emergency "morning-after" pills and emergency IUD insertion. These methods can be effective in reducing the risk of pregnancy if started within a few days after unprotected sex. They offer no protection against STDs (including HIV).

For HIV+ women, drug interactions and the need to reduce the risk of disease transmission can complicate choosing a method of birth control. Work closely with your health care provider or a family planning counselor to decide on the contraceptive that is best for you.

It is important to get accurate and up-to-date information on any birth control method you choose. You may want to ask the following questions about different methods:

• Does it provide protection from sexually transmitted diseases (STDs) including HIV?
• Does it interact with my HIV drugs or other drugs I am taking?
• How well will it fit into my lifestyle?
• How convenient will it be?
• How effective is it?
• How safe is it?
• How affordable is it?
• How will it impact my chances of getting pregnant in the future if I choose to?
