G-Cimetidine Cimetidine Citalopram Hydrobromide
MajorCitalopram should not be taken together with cimetidine. The leaflet gives no reason for this, only that the two should not be used at the same time. The same warning also covers MAOIs and several other medicines, so check with your doctor or pharmacist if you take any of those.
These medicines can affect each other in a serious way. Do not start taking them together unless your doctor has said it is OK. If you already take both, do not stop either one on your own: speak to your doctor or pharmacist soon.
