Do Antibiotics Make Birth Control Not Work

Nigh antibiotics do not affect contraception. It's now thought that the only types of antibody that collaborate with hormonal contraception and brand it less effective are rifampicin-like antibiotics.

These tin exist used to care for or preclude diseases, including tuberculosis and meningitis.

They include:

• rifampicin
• rifabutin

These types of antibiotics tin increase the enzymes in your body. This is known every bit being "enzyme-inducing" and tin can impact hormonal contraception.

If you're taking enzyme-inducing antibiotics while using hormonal contraception, to avoid getting meaning you'll demand to:

• utilise additional contraception, such as condoms
• change to a different method of contraception, or
• take your contraception in a unlike way

Apart from rifampicin and rifabutin, all other antibiotics are non enzyme-inducing.

Only the patient information leaflet that comes with other types of antibiotics may say they could affect your contraception.

This information may exist unlike from show-based guidelines used past health professionals.

Additional contraception when taking antibiotics

If y'all're going to take rifampicin or rifabutin for more than 2 months, you may desire to consider starting, or irresolute to, a contraception method that's not affected by these medicines.

You should consider doing this if y'all're currently using:

• the combined pill
• the progestogen-only pill
• an implant
• a patch
• a vaginal band

Contraception methods that are non affected by rifampicin or rifabutin include:

• the progestogen-only injection
• an intrauterine device (IUD)
• an intrauterine system (IUS)

If you're taking rifampicin or rifabutin for less than 2 months and desire to proceed using the same hormonal contraception, you must discuss this with your doctor.

You may be asked to take this contraception in a different style from usual and employ condoms equally well.

Y'all'll demand to continue this for 28 days after finishing the antibiotics.

One selection for women who accept a contraceptive implant and need to take a short dose of rifampicin (for preventing meningitis, for instance) is a single dose of the progestogen injection.

The implant can stay in place while you're covered past the injection.

Yous and your doctor tin can go up-to-date guidance about contraception and antibiotics from the Faculty of Sexual and Reproductive Healthcare.

You lot do not usually need to apply boosted contraception if yous're taking antibiotics other than rifampicin and rifabutin.

But if the antibiotics or the disease they're treating cause diarrhoea or vomiting, assimilation of the contraceptive pill may be affected.
