ACCESSIBLE DRUG LABELS AND CONTAINERS
If you’re having trouble reading your prescription label, talk with your doctor or pharmacist. Some pharmacies offer labels with large print, braille, or a code you scan with a smartphone to convert text to speech. If your local pharmacy doesn’t have these options, your doctor or pharmacist might be able to recommend a pharmacy that does.
If you’re having trouble opening medication bottles, ask your pharmacist about putting Ingrezza in an easy-open container. They also may recommend tools that can make it easier to open bottles.
If you miss a dose of Ingrezza, take it as soon as you remember. However, if it’s almost time for your next dose, skip the missed dose. Then, take your next dose at the regularly scheduled time.
Do not double up or take two doses to make up for a missed dose. If you need help deciding whether to take a missed dose, ask your doctor or pharmacist.
To help make sure that you don’t miss a dose, try using a medication reminder. This can include setting an alarm or using a timer. You could also download a reminder app on your phone.
It’s important that you do not take more Ingrezza than your doctor prescribes. For some medications, taking more than the recommended amount may lead to side effects or overdose.
If you take more than the recommended amount of Ingrezza
Call your doctor right away if you believe you’ve taken too much Ingrezza. Another option is to call America’s Poison Centers at 800-222-1222 or use its online tool. If you have severe symptoms, immediately call 911 or your local emergency number, or go to the nearest emergency room.

How long will my doctor wait before increasing my dosage of Ingrezza?
