hi dr. my child is 3 months old,, when he was of 2 months i noticed that his legs shakes and his eyes moves upwards. one dr. adviced gardinal 30 mg one third tab. twice a day. i gave him and there is improvement in eyes but his legs shakes at times i gave it for 1 month. second dr. adviced me to do its calcium test and it is normal. i want to know is my child fine and y dr. adviced gardinal

Since 2012 i was taking gardinal 60 mg HS,now doctor changed my medicine from gardinal to levipil 250 mg because i want to take another medicine of hepatitis -c which have sofosbuvir as chemical compound, so can i take gardinal and levipal both till the doctor stop gardinal and continued the levipil for the whole life?

what is this used for?

what will happen if a person takes 3 tabs of eptoin 100mg and gardinal 60mg continiously for more than 2.5 years (with doctors prescription) and in the year 2007 i had hydrophalus VP-shunt surgery thrice ?
