1 milligram = 1000 micrograms
So u need to take folic acid tablet 2 and half tablet per day.
Since it is stage IV lung cancer the doctor may be planning chemotherapy with agent called pemetrexed which is used in subtype of non small cell lung cancer called adenocarcinoma.
Vitamin B12 and folic acid are needed to prevent pemetrexed toxicity such as anaemia and low platelet .
Regards and take care.
