Welcome to healthcare magic!
The dose of Meftal spas
is more than needed for you so you should take half tablet thrice a day, I think it would be as effective as a full tablet.
You should also get the treatment for the PCOD
under the supervision of experienced Gynecologist.
PCOD is a common disorder of reproductive age group and is associated with disorders of menses.
I hope this advise would be helpful for you.
Wish you a great health!
