Anti-depressant addiction warning

Prozac, and other new generation antidepressants are used by thousands

 

Thousands of people in the UK could be hooked on the anti-depressant

drug Seroxat (Paxil), without knowing it.

 

Dr David Healy, a UK expert in antidepressants, has said he has seen

records of trials carried out by the manufacturers which showed

healthy volunteers were suffering withdrawal symptoms after taking the

drug for just a couple of weeks.

 

He said more than half of people on Seroxat may have " significant "

withdrawal problems.

 

He said: " For most people who take the drug, one of the key points

that will concern people is that Seroxat (paroxetine) could make you

physically dependent. "

 

One of the key points that will concern people is that Seroxat could

make you physically dependent

 

Dr David Healy: Dr Healy, director of the North Wales department of

psychological medicine was given access to the results of early

trials of the drugs while a witness in a US case.

 

The case dealt with a seperate concern about the drug, which is that

some people who take it could become violent towards themselves or others.

 

The family of David Snell won a $6.4m payout from manufacturers

GlaxoSmithKline (GSK) after Mr Snell was found to have murdered three

members of his family, and himself, after taking the drug for just

two days.

 

The company denies the link and is appealing against the decision.

 

Two weeks earlier, in Australia, a judge ruled Sertraline, a drug in

the same family, had caused David Hawkins to murder his wife and

attempt to kill himself.

 

Dr Healy told BBC News Online, of the 100m people world-wide who were

on Seroxat, one in 1,000 could have a suicidal reaction.

 

There have been concerns expressed in the past about antidepressants

such as Prozac making healthy people with no history of mental illness

feel violent.

 

 

New generation

 

Seroxat is part of a family of antidepressants called SSRIs (selective

serotonin re-uptake inhibitor) which were introduced to the market in

the early 1990s.

 

They were a replacement for benzodiazepines such as Valium and

Librium - and their selling point was that people would not become

physically dependent on them, unlike the older drugs.

 

Dr Healy was given access to GSK's archives because he was an expert

witness in the Snell case.

 

And he said a trial a study of 34 healthy company workers by GSK,

carried out before Seroxat was licensed, showed 25% became agitated.

 

Dr Healy believes a small number could be so disturbed by the effects

of SSRIs that they could kill.

 

He said some of those involved in the pre-licensing trial had gone on

to " suicidal acts " .

 

He wrote to the Medicines Control Agency, which grants drug licenses

in the UK, and said: " The relationship between their intake of

paroxetine (Paxil/Seroxat) and later suicidal acts is a matter about

which neither you, nor SmithKline Beecham should be sanguine. "

 

Dr Healy said the company has failed to pass on information to

patients or doctors.

 

'Warning' call

 

He says a study which looked at the effect of stopping the drug for

people who had successfully been treated for the depression showed

many got worse.

 

The company argued this meant the drug should be licensed for long

term treatment of depression.

 

Dr Healy says this is potentially more evidence that the participants

in the trial were suffering withdrawal symptoms.

 

He said the drug should carry warnings that some people who take it

may experience violent or unusual thoughts, which were linked to the

drug and not their condition.

 

And he said doctors who were treating people who suffered symptoms

after coming off the drug " should be aware that maybe the underlying

problem has cleared up and maybe the symptoms are due to withdrawal. "

 

'Withdrawal problems'

 

A World Health Organization report which ranked antidepressants in

order of withdrawal problems found Seroxat was the hardest to come off.

 

Prozac (fluoxetine) was seventh.

 

Alan Chandler, a spokesman for GSK denied Seroxat caused dependency,

withdrawal symptoms or violent tendencies.

 

He said independent analysis last year by the MCA and others had

concluded SSRIs did not cause dependency.

 

He said: " Withdrawal symptoms may occur with all SSRIs if treatment is

abruptly stopped. This is not a sign of addiction or depression. "
