How to use Abstral Tablet, Sublingual
Read the Medication Guide provided by your pharmacist before you start using fentanyl and each time you get a refill. Learn all usage and disposal instructions. If you have any questions, ask your doctor or pharmacist.
Use fentanyl sublingual tablets as directed by your doctor. If your mouth is dry, take a sip of water to moisten it before using this medication. Spit out or swallow the water. With dry hands, open the blister pack unit just before using. Do not push the tablet through the foil of the blister pack because this could damage the tablet. Place the tablet in your mouth under your tongue, as far back as you can. If your dose is for more than one tablet, spread them around the floor of your mouth under your tongue. Do not break, bite, chew, suck, or swallow the tablet whole. Do not eat or drink anything until the tablet dissolves completely.
The dosage is based on your medical condition and response to treatment. To reduce your risk of side effects, your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor’s instructions carefully. If you need a second dose, wait 30 minutes after starting the first dose. Do not use more than 2 doses per episode of breakthrough pain. Wait at least 2 hours before using fentanyl sublingual tablets again for another episode of breakthrough pain. Do not increase your dose or use this drug more often or for longer than prescribed.
You should continue to also take your around-the-clock opioid medication as directed by your doctor. Other pain relievers (such as acetaminophen, ibuprofen) may also be prescribed. Ask your doctor or pharmacist about using fentanyl safely with other drugs.
