You should not mix follitropin alfa and lutropin alfa with other medicines in the same injection, but studies show you can give follitropin alfa together with it because co-administration does not significantly alter the activity, stability, pharmacokinetic or pharmacodynamic properties of the active substances.
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.
