I grew up on 'When Doves Cry'. Purple Rain was the soundtrack to my youth - so I was as shocked as any to hear of Prince's death at the age of 57. Only after his death did we hear about the crippling joint pain that had blighted so much of his life. And only now has it come to light that he may have died of an accidental overdose after taking counterfeit painkillers.
The most common reason I prescribe either morphine or fentanyl is for terminally ill patients. Doctors use 'opioid conversion charts' to make sure that when they switch from one to another, they're giving approximately the same dose in terms of pain relief. Hydrocodone is weaker than morphine - fentanyl is many times stronger.
I most commonly prescribe fentanyl in the form of patches applied to the skin, which release a steady dose of pain relief. The dose of these patches is measured in micrograms - millionths of a
Disguising counterfeit drugs containing strong opioids like fentanyl as weaker tablets would be an obvious way to bypass customs. Most pharmacies will get their supplies from reputable sources - but buying drugs from the internet is a completely different story.
The World Health Organization estimates that 1% of drugs in developed countries, and up to 10% of drugs globally, are counterfeit. Just two years ago, the UK drug regulating agency, the Medicines and Healthcare products Regulatory Authority (MHRA), seized millions of pounds' worth of counterfeit medicines. When they were analysed, ingredients included banned medicines, blue paint and rat poison. They were recovered from filthy buildings with broken windows and vermin roaming around. But the drugs themselves were professionally and convincingly packaged - it's a multi-billion dollar industry.
In theory, Prince may have known the drugs he took were counterfeit. But even if he did, he's highly unlikely to have realised the risks. No drug is licensed without a full assessment of its risks and benefits. On the whole, the more powerful the drug, the higher the level of side effects - and the more cautiously it's used by doctors.
Fentanyl gives a very fast 'high' to recreational users because it's so quickly absorbed into the system. It's also completely synthetic, which makes it easy to manufacture in large quantities. But at high doses, fentanyl (like all opioids) can suppress breathing - and that too happens with frightening speed. Use it in combination with other opioids like hydrocodone and the risk rises. Lidocaine can cause irregular heart rhythms or even cause the heart to stop. A combination of the two is a disaster waiting to happen.
We may never know the truth about what happened that night at Paisley Park. We do know an extraordinary man was cut down well before his time. We also know that counterfeit medicines may have played a part. And if it can happen to Prince, it can happen to anyone. It may not be the legacy he wanted, but I'd like to hope that it makes anyone who's tempted stop and think. Counterfeit drug manufacturers only have one person's interest at heart - and it's most definitely not the 'patient'.
