Eliquis is typically intended to be used twice a day. Doctors may recommend taking it 12 hours apart, since this medication has a half-life of 12 hours. Individuals should discuss daily recommended dosage times with their doctor. If a dose is missed, individuals should not take double the amount to make up for it, since taking too much at once may increase the risk of bleeding. Instead, they should take Eliquis as soon as possible and resume taking it twice a day after that.
