ACCESSIBLE DRUG LABELS AND CONTAINERS
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 Quviviq in an easy-open container. They also may recommend tools that can make it easier to open bottles.
To work effectively for insomnia, Quviviq should be taken within 30 minutes of bedtime. If you miss a dose, take it only if you have 7 hours before you need to wake up.
To help make sure that you don’t miss a dose, try using a medication reminder. This can include setting an alarm or putting a note where you’ll see it, such as on your bathroom mirror or bedside table. You could also download a reminder app on your phone.
Quviviq is a Schedule IV controlled substance* due to the risk of misuse. (With misuse, a drug is taken in a way other than how it’s prescribed.) However, there were no reports of Quviviq misuse by people who took the drug for 12 months in a clinical trial.
