Thank you for your query.
Why is your daughter receiving sodium valporate, amitriptolene and beta blockers? Does she have hypertension?
In the initial stages of menarche
the menstrual periods can be irregular and can occur after a few months. However the nosebleed is normal. It is advisable that you get her blood pressure checked up.
I hope I have answered your query to your satisfaction.
Wishing your daughter all the best.
