Hi Paul,
The primary issue for divers taking prescription narcotic pain relievers like Co-Codamol 30/500 (30mg codeine/500mg paracetamol) is the drug's action on the central nervous system. Side effects can include dizziness, drowsiness, impairments in mental performance and alterations in mood. These typically are strongly dose-related and the lower the amount, the less frequent and severe the adverse reactions.
The individual who has used such a medication over an extended period should have a good appreciation of any side effects s/he may be experiencing. If no worrisome reactions are present, and ability to attend, concentrate, make decisions and modulate behavior are appropriate to the demands of SCUBA, there should be minimal additional risk to diving.
There also is the matter of why this drug is being used, which is as yet unspecified. The diver requiring narcotic medication must insure that the condition for which it is being taken does not significantly limit the physical ability to SCUBA and that the demands of SCUBA (e.g., donning and doffing gear, carrying and manipulating heavy objects) do not exacerbate the discomfort.
As regards how long an individual would have to be off such a drug before s/he could safely return to SCUBA, codeine has a short half-life and it's effects should no longer be discernable a day after the last dose. However, the total daily dosage taken and the length of time the drug has been used also have yet to be specified. It is possible the prescribing doctor may want to taper the dose and the patient should not completely discontinue the drug without instruction to do so.
In any event, the individual's physician should give clearance to dive before engaging in the activity.
Helpful?
