About Sevodyne

What is Sevodyne?

Sevodyne contains the active ingredient buprenorphine which belongs to a group of medicines that are called strong analgesics or ‘painkillers’. These are prescribed in the form of a transdermal patch to relieve moderate, long lasting pain that requires the use of a strong painkiller.

What is pain?

Pain is a signal in your nervous system that something may be wrong. It is an unpleasant feeling, such as a prick, tingle, sting, burn, or ache. Pain may be sharp or dull. It may come and go, or it may be constant. You may feel pain in one area of your body, such as your back, abdomen, chest, pelvis, or you may feel pain all over.¹

Pain can be helpful in diagnosing a problem. If you never felt pain, you might seriously hurt yourself without knowing it, or you might not realise you have a medical problem that needs treatment.¹

There are two types of pain: acute and chronic. Acute pain usually comes on suddenly, because of a disease, injury, or inflammation. It can often be diagnosed and treated. It usually goes away, though sometimes it can turn into chronic pain. Chronic pain lasts for a long time, and can cause severe problems. ¹

Sevodyne is licensed for the treatment of non-malignant pain of moderate intensity when an opioid is necessary for obtaining analgesia.² Sevodyne is not licensed for the treatment of acute pain.²

What causes chronic pain?

Chronic pain may last for weeks, months, or even years. The original cause may have been an injury or infection. There may be an ongoing cause of pain, such as arthritis or cancer. In some cases there is no clear cause. Environmental and psychological factors can make chronic pain worse.³

Chronic pain is not always curable but there are treatments that can help relieve the pain.³

Although Sevodyne is licensed for chronic pain it is not licensed for malignant pain (i.e., pain related to cancer). Treatment should not be continued for longer than absolutely necessary.²
