Anthrax alert at US consulate

The demand for Cipro has shot up all over the world

A package was being taken for x-ray when one of the men noticed the powder on Monday.

They were isolated and showered down before being taken to hospital as a precaution.

Their clothes and the package were taken away for analysis.

Meanwhile, an expert has warned that unnecessary use of the anthrax antibiotic ciprofloxacin could undermine the effectiveness of the drug.

It may also compromise the effectiveness of other antibiotics used to treat a range of disease.

There is growing evidence that many people in the US are ignoring public health messages and stocking up on the powerful antibiotic.

The drug can also be easily purchased on the web from foreign manufacturers.

Dr Richard Corlin, president of the American Medical Association (AMA), said that widespread use of Cipro would increase the possibility that anthrax spores would develop resistance to the drug.

He said: "If we have hundreds of thousands of people taking antibiotics unnecessarily we are going to see resistant strains, and it is not just anthrax, we are going to see resistant strains of other organisms."

Dr Corlin accused people who were making Cipro available to the public of "cashing in".

He said: "Whether they are physicians, pharmacists, or business people, we do wish they would stop because they are hurting the public."

Side effects

Cipro is a powerful drug that is not recommended for use by children.

It can produce a number of unpleasant side effects. These include:

• damage to the central nervous system such as dizziness, confusion, tremors, hallucinations, depression and increased risk of seizures
• an allergic reaction which can produce difficulty breathing; closing of the throat; swelling of the lips, tongue, or face and hives
• severe tissue inflammation of the colon
• increased sensitivity of the skin to sunlight
