Why not just put Tamiflu in the water..?

Hello again dear reader,

Been getting loads of feedback via twitter (@GPforhire) about my last posting. Apparently you didn't realise that Tamiflu isn't all its cracked up to be. Not surprising really as the negative side of tamiflu has had very little coverage. I could be paranoid and think that the government is suppressing reports of its lack of efficacy and side effects but is Labour capable of that?

Things are changing a little, there was this report in the Guardian today, and a previous one in May. I saw a young child last week that got a nasty rash from the drug. We've had multiple patients that couldn't tolerate the tamiflu due to vomiting and then phone us in a panic worried that they'd succumb to Swine Flu without their magic bullet drug.

Just so you know that I'm not making this up heres a few links that have looked at various bits of data.
You might have to be a BMA member to see the full articles

Tamiflu and anti-inflammatories (aspirin, ibuprofen or diclofenac) might be a nasty combo
GPs seeing lots of patients with side effects from Tamiflu
Tamiflu and neuropyschiatric side effects in teenagers - case not proven, caution recommended
Use of Tamiflu in children not supported by the evidence

So for the record, I wouldn't take Tamiflu, and neither would anyone in my family. Not for Swine flu anyway. For Avian flu I'd probably take it but resistance to it is growing.

Another worrying development:

Misdiagnosis.

I know of 3 deaths that have happened recently because they were thought to have Swine Flu but sadly had something much more serious which was missed until it was too late. This number will increase as the number of people assuming they have Swine Flu when they have something else will no doubt increase.

We run a simple problem clinic at our practice (see my earlier blog entry). Its been nearly empty this week. Summer holiday don't make that much difference to the numbers. I think its because these patients are confusing their symptoms with Swine Flu and using the Pandemic Line to get their tamiflu. These patients will probably turn up next week complaining of side effects from their treatment for their non-existent Swine Flu. I know some docs who have been swabbing patients still. Roughly 10% of the patients they thought had Swine flu actually had it on swabs. Thats experienced GPs seeing patients face to face and are still getting it wrong 90% of the time. God knows what the general public numbers would be like. Its madness frankly. Countless thousands of people taking Tamiflu (via the Pandemic line) for a mild self-limiting illness which they haven't even got!!


Quick link before I go. Heres a website run by the Medicines and Healthcare products Regulatory Agency MHRA. You can report any side effects from Tamiflu here. Tamiflu is a black triangle drug and so all side effects (even minor ones) should be reported. Its how we get to know if a drug is doing something odd. Anyone can report a side effect, doctor or patient.

Stay Healthy and see you again soon!

The Week that Was

So its the end of my first week back at work and the Swine Flu panic, er, I mean pandemic is in full swing. We are getting 30-40 patients a day worried they have it. Some do, some don't. Should we be giving them all Tamiflu? Well that depends on what guidelines you read and whether you are bothered by something called evidence-based medicine.

You're no doubt aware of the mountainous piles of Tamiflu the government has stockpiled. Let's get one thing straight. Tamiflu is an antiviral but this doesn't mean its a cure. Its not like taking an antibiotic for pneumonia. At best it will shorten the duration of symptoms by a day. The evidence so far has shown it has no impact on mortality (i.e taking it won't stop you from dying if thats your fate). Its use in a pandemic is unproven.

Lets not forget all the side effects. We are already seeing children who get quite nasty vomiting from it (1 in 10). Trouble is you tell the parents to stop the drug and they shit themselves, convinced that Tamiflu is the only thing stopping their child from knocking on heavens door. So the child vomits themself into dehydration and ends up needing admission.

Interestingly a large study of Tamiflu's potential neuropyschiatric side effects showed a possible increase in seriously abnormal behaviour (such as self-harm) in the under 19s. Its not meant to be used in Japan for this age group such is the number of cases they have had. Of course in this country we have no such qualms in giving it to our children. Tamiflu is classed as a black triangle drug in the UK- this means its a new drug, not all the side effects (or frequency of) are known, or the potential interactions.

One of the high risk groups for complications of Swine Flu is the under ones. The UK has a limited supply of liquid Tamiflu for this group. Guidelines state that all under 1's should be offered the drug. Trouble is is that it doesn't work, no evidence it works and I've been informed via a consultant Neonatologist that the under 1's lack the enzyme to activate it. Also the blood brain barrier hasn't fully formed yet meaning the drug that is known to cause hallucinations and confusion can easily pass into their developing brain. Brilliant. Is that in the press? Hell no, its not even in the Daily Mail which hates all things medical.

Now don't get me wrong. I'm not trying to scaremonger. I'm just letting you know that Tamiflu might make you quite sick, or worse. It lacks evidence of effectiveness and I'd think twice about giving it to anyone under 18.

One flu over the Swine nest

Good evening dear Reader,

I write this as I am watching Bear Grylls eat frozen squirrel brains in a Siberian forest. Still, if its a choice between that and Kendal Mint cake I know what I'll go for.

Work is vaguely interesting at the moment. We are all going to die from Swine Flu.

Or maybe not. In January of this year the RCGP published its Pandemic Flu guidelines which gave information about what do in the event of a new global flu pandemic. It was based on models from previous flu pandemics last century (that makes me feel old) with mortality rates etc... from Avian Flu. That was assumed to be the Big One. Its nasty, it kills a lot of people. Much to everyones surprise it was actually Swine Flu (H1N1) that swept the planet.

So far its killed a few hundred people and infected many tens of thousands (at least). Although these deaths are tragic, things should be put into perspective. Seasonal Flu (normal flu) kills 12000 per year in the UK. Does it get the same kind of hysterical coverage in the media? Not a chance. Mind you I can't be too tough on the media and the government (for once) as their projections were based on the far more deadly Avian flu.

How's things panning out now? Well I'm sure you are aware that Swine Flu is a lot milder than everyone was expecting. True it has killed people but the majority of these had other significant illness (not sure what exactly as no-one will tell us). One person died today of Swine Flu who was otherwise healthy. I am assuming they died from viral Pneumonia - v.nasty but rare, 40% mortality rate.

We've had a few cases through the doors where I work - despite advice to stay at home. I think currently the Staff are more scared then the patients. The difficulty is the guidance coming out from the PCT is mixed, frequent and far too wordy. I get 2-3 emails per day with 4-5 attachments. Each email supersedes the previous one - usually. Its a fucking mess. The Swine flu packs never turned up - not that they are needed now. Tamiflu guidance seems to change every few days. I'm still unsure if its for people presenting within 48hrs of symptoms, just the high risk groups, or everyone. Not that its any good. Government seems to think its a silver bullet but the evidence behind its use is not brilliant. Shortens the illness by hours, reduced viral load but its not without its side effects - including making all your skin fall off (rare but if everyone uses it we might see a case or two)!

Don't get me started on NHS Direct. Fucking waste of space that is. Masks are pointless too but good for scaring patients. I think a lot of the problems come from the original guidance which was based on Avian flu. Which is nasty and kills a lot of people. Where as Swine flu just makes you feel a bit poorly (usually). The guidance is slowly changing to take account of the fact that its not the End of humanity as we know it.

How you diagnose Swine flu? You guess. Thats right. We've been given a few symptoms that people will have but the trouble is is that the vast majority of viral infections we see in GP-land present with this. Even worse with children. Its only a matter of time before we miss a serious illness (meningitis, cancer, etc...) as we are so focused on believing everyone who is unwell has Swine Flu. And then the Daily Mail will have a field day. Whoop-de-fucking-doo.

Of course come winter the shit will hit the fan when Swine flu grows some balls and becomes the killer that we are all worried about. Oh well, such is life.
