Questions before treatment

Menogon

Hi, I have a question about Menogon. My menogon from my last attempt expired 6 months ago. My doctor said I could still use it. I also called the manufacturer again and they said I had to dispose of it. What is your opinion on this? We are only self-pay and the drug is very expensive. Can the effectiveness of Menogon be affected or are there serious side effects if I inject the expired Menogon?
