This medicine can impair cognitive function and can affect a patient’s ability to drive safely. This class of medicine is in the list of drugs included in regulations under 5a of the Road Traffic Act 1988. When prescribing this medicine, patients should be told:

•    The medicine is likely to affect your ability to drive

•    Do not drive until you know how the medicine affects you

•    It is an offence to drive while under the influence of this medicine

•    However, you would not be committing an offence (called ‘statutory defence’) if:

o The medicine has been prescribed to treat a medical or dental problem and

o You have taken it according to the instructions given by the prescriber and in the information provided with the medicine and

o It was not affecting your ability to drive safely

5. PHARMACOLOGICAL PROPERTIES

5.1. Pharmacodynamic properties

Dihydrocodeine is a narcotic analgesic which possesses pharmacological properties similar to those of morphine. 30mg given parenterally has been shown to have an analgesic potency equivalent to that of 10mg morphine. In a study of oral analgesics for the relief of chronic pain, the same dose was found to be equivalent to 100mg of pethidine. The duration of action of dihydrocodeine is about 4-5 hours, similar to morphine and codeine.

5.2. Pharmacokinetic properties

Dihydrocodeine Elixir has been shown to have a satisfactory pharmacokinetic profile by many years of successful clinical experience.

5.3. Pre-clinical safety data

There are no pre-clinical data of relevance to the prescriber which are additional to that already included in other sections of the SPC.
