How much to take
The recommended dosage will depend on the level of pain you are experiencing.
When starting ABSTRAL
You must start with the lowest dose tablet (100 microgram). If adequate pain relief
is not achieved within 30 minutes, your doctor may recommend a supplemental (second)
100 microgram tablet.
If your pain is still uncontrolled after the second dose you cannot take another ABSTRAL
tablet for this episode of pain.
If adequate pain relief was not achieved for an earlier episode of breakthrough cancer
pain, your doctor may suggest you take additional tablets or higher strength tablets
for your next episode(s) of breakthrough cancer pain. This is because everyone's pain
is different and finding the right dose for you is important.
Do not take more than two doses of ABSTRAL for each episode of breakthrough cancer
You should wait at least 2 hours before taking ABSTRAL to treat another episode of
breakthrough cancer pain.
After you have found the right ABSTRAL dose
After you and your doctor have found the dose of ABSTRAL that provides adequate breakthrough
cancer pain relief for you, this is the ongoing dose that you should take for each
episode of breakthrough cancer pain.
DO NOT TAKE MORE THAN THE DOSE YOUR DOCTOR HAS RECOMMENDED FOR EACH EPISODE OF BREAKTHROUGH
You must tell your doctor immediately if you are using ABSTRAL more than four times
per day, as the doctor may wish to change your medicine for your chronic cancer pain.
Once your chronic pain has been controlled, your doctor may need to change your dose
of ABSTRAL further.
For best results, let your doctor know about your pain and how ABSTRAL is working
for you so that the dose can be changed if needed.
Do not change doses of ABSTRAL or your other pain medicines on your own.
Contact your doctor if your recommended dose of ABSTRAL does not relieve your breakthrough
cancer pain. Your doctor will decide if your dose needs to be changed.
How long to use it
You can use this medication whenever you have an episode of breakthrough cancer pain.
You should discontinue ABSTRAL when you no longer have any breakthrough cancer pain.
You must however continue to take your usual opioid pain relieving medicine to treat
your persistent cancer pain as advised by your doctor. You may experience withdrawal
symptoms similar to the possible side effects of ABSTRAL when discontinuing ABSTRAL.
If you experience withdrawal symptoms or if you are concerned about your pain relief
you should contact your doctor. Your doctor will evaluate if you need medicine to
reduce or eliminate the withdrawal symptoms.
Do not continue to use ABSTRAL if you no longer feel breakthrough cancer pain.
If you take too much (overdose)
Immediately telephone your doctor, or the Poisons Information Centre on 13 11 26 for
