Hi there ~
I understand your concerns and it seems to me that you want to know that risks and benefits of each of the medication that has been prescribed to you. While I found that Benforce
M is a combination of benfothiamine and metformin
plus is a multivitamin
supplement, there is no literature on the web about Luirfur mrtre. The multivitamins and benfothiamine are essential nutrients for your body and I believe you would not have any side effects from the medications. Metformin is a medication used mostly for diabetes as well as sometime weight loss, please consult your doctor
for the reason you were prescribed the medication. I also advise you to take the medication after researching the + and - of these on an authentic website like that of the national institute of medicine.
I hope this helps.
Take care and have a lovely day!
