Pregnancy and breastfeeding while having medroxyprogesterone contraceptive injections

Do not have a medroxyprogesterone contraceptive injection if you think you might be pregnant.

If you find that you're pregnant after having the injection, talk to your doctor. But do not worry, as the injection only gives a small amount of progesterone over a long period of time and is unlikely to affect your baby.

It's OK to have a medroxyprogesterone contraceptive injection while you're breastfeeding.

It passes into breast milk in very small amounts and your baby will not be able to absorb a lot into their body from the breast milk. It has not been known to cause any side effects in breastfed babies.

If you notice that your baby is not feeding as well as usual, or if you have any other concerns about your baby, talk to your doctor, pharmacist, health visitor or midwife as soon as possible.

Tell your doctor if you're:

• trying to get pregnant
• pregnant
• breastfeeding
