What should I know before using Durogesic patches?
If you have suffered any of the following, please tell your doctor before using Durogesic patches because your doctor might need to check you more closely.
• Problems with your lungs or breathing
• Problems with your heart, liver or kidneys
• Brain tumours
• Headaches or a head injury
If you are very ill, very thin or elderly, you may be more sensitive to the effects of Durogesic patches.
If you develop a fever while wearing Durogesic patches, tell your doctor as this may affect the way the drug passes through your skin.
You should avoid exposing the Durogesic patch area to direct heat, for example, heating pads, hot-water bottles, electric blankets, heat lamps, saunas or hot whirlpool spa baths, as this may affect the way the drug is released from the patch.
Like many other strong painkillers, repeated use of Durogesic patches may make you ***become tolerant to the medication*** or become dependent on it.
Like some other strong painkillers, Durogesic patches may make some people unusually drowsy, and breathe more slowly or weakly than expected. If you, or your partner or helper, notice that you are breathing much more slowly or weakly than expected, take the Durogesic patch off immediately. Call a doctor straight away. While waiting for the doctor, you must keep moving and talking as much as possible.
