HOW TO TAKE SYMDEKO®

SYMDEKO and fat-containing foods

SYMDEKO should always be taken with a fat-containing meal or snack to help the body absorb the medicine. You can find ideas for fat-containing foods here.

Every dose matters

Together, the medicines that make up SYMDEKO target the underlying cause. Talk to your healthcare provider about all of the medicines you or your child takes, as the dose of SYMDEKO may need to be adjusted. Be sure to take every dose exactly as prescribed by your healthcare provider, because every dose matters.

If you or your child misses a dose

6 hours or less
from the time you 
or your child usually takes the morning 
or evening dose 

Take the missed dose with fat-containing food as soon as possible. Then take the next dose at the usual time.

More than 6 hours
from the time you 
or your child usually takes the morning

Do not take the missed dose. Take the next dose at the usual time with fat-containing food.
