R- Cinex is a combination of 2 drugs Isoniazid
and Rifampcin; generally prescribed for tuberculosis
or for prevention of tuberculosis. I wonder why your husband would prescribe you and you would take R CInex. It is usually taken for 4-6 months for tuberculosis. Please don't take medication without prescription from a health care practitioner. It also causes serious side effects like damage to liver; nerves, nausea
etc. So to answer your question again don't take it.
