meningitidis (which causes meningitis).

Pregnancy and breast-feeding
Ask your doctor or pharmacist for advice before taking this medicine.

means you should change to a different type of contraception. You
must use a reliable barrier method of contraception such as condoms
or the “coil” while taking Rifampicin. If you have any questions or are
unsure about this talk to your doctor or pharmacist.
Do not breast-feed your baby, as small amounts of rifampicin can
pass into breast milk.
