UK: 150,000 Rx For Antivirals In A Week

 

 

# 3564

 

 

It’s an astonishing number, really. 

 

In the first week of operation, the NHS hotline has reportedly given out 150,000 vouchers for Tamiflu over the phone.

 

Unlike most countries, where antivirals are being reserved for those with high risk comorbid conditions – like pregnancy, diabetes, or chronic pulmonary disease – or for those with particularly severe symptoms, antivirals according to this report are being  handed out to just about anyone with flu-like symptoms.

 

 

 

Swine flu: 150,000 people take up antiviral drugs

An estimated 150,000 people were prescribed with antiviral drugs last week following the launch of the swine flu hotline and website.

 

The Health Protection Agency estimated that a further 110,000 new cases in England last week were diagnosed by doctors.

 

At present Tamiflu (oseltamivir) is being offered to anyone with identifiable swine flu symptoms.

 

Access to the treatments remains patchy, it has been claimed, while researchers say that some groups may benefit more than others from taking the drugs.

 

Since the launch of the National Pandemic Flu Service last week people suffering symptoms have been able to take an assessment questionnaire over the phone or on the internet.

Those who appear to have the H1N1 virus are given a unique number which can be given to a friend who can then pick up the prescription. There are over 1,100 collection points for the drug.

This sort of liberal dispensing of antivirals is a two-edged sword.

 

It may very well reduce the number of hospitalizations, and even deaths, that a country might experience.   It may also reduce the spread of the virus, by limiting the amount of virus being shed by those infected.

 

But there are potential downsides as well.

 

There is considerable concern that overuse of antivirals could lead to resistance developing in the virus.    Already nearly all seasonal H1N1 viruses tested show resistance to Tamiflu, and the fear is that the novel H1N1 could follow suit.

 

That may not happen of course.

 

Or it could happen, whether antivirals are liberally dispensed or not.   There is a lot here, we simply don’t know.

 

Additionally,  Tamiflu is a drug.  And like all drugs, it can had adverse side effects.  Most that have been reported have been mild, but there is always a tradeoff between the risk of taking a drug and the benefits derived.

 

If a large number of people are taking Tamiflu that don’t really need to be taking it, then they are presumably incurring some small additional risk.   How small that risk might be is hard to gauge.

 

Politically, I’m sure it is very difficult for the NHS to deny hot line callers antivirals when A) they have them stockpiled  and  B) GPs are overwhelmed and cannot guarantee to see and evaluate patients during the critical first 24-48 hours of an illness.

 

All it would take to undermine public confidence in the NHS’s pandemic plans would be for someone to be denied antivirals who really needed them, and for them to come to a bad end.

 

The tabloids would have a field day with that kind of story.

 

Difficult questions, and no easy answers.

 

And issues that the US, and other countries are going to have to wrestle with over the next few months as well.
