Have refill on 30 mg cymbalta, (duloxetine) but doc increased dose to 60 2 weeks ago. Should I refill 30 or request script for 60? Does it matter?

Ask for 60. and double up on the 30 mg pills you have at home-I am sure that this will not be an issue.
Cymbalta (duloxetine) Does not matter, 2 of 30's or 1 of 60's. However, if you refill the 30's you run out sooner. Your doctor can call in the 60's to your pharmacy.
