Something wrong then.
I have had treatment there for 18 months, and continuing.
I had to pay for infusor appx, 800 pesos, emend tablets appx 2000 pesos ,optional, acido foliatico 2000 pesos, twice a month.
The actual chemo was always free.
This was for appx a year.
From July all items were available for free.in december i started with new treatment tablets to take at home. Cost 7000 pesos. Free under s.p.
I would get your friend to check, its not expensive even when some items arent available.
