Thanks for your query.Folic acid
is one of the Vitamin B. Conventionally, 5mg of Folic acid is adequate. However, in my vast experience, I have not come across any adverse effects in those patients who had been taking double the dose for long periods.
Nevertheless, you should continue with Folvit, since each tablet of autrin contains only 1.5mg of folic acid. It is perfectly OK.
