Botox Offers Little Help In Treating Chronic Migraines

The popular anti-wrinkle drug Botox unlikely to offer much benefit as a treatment for chronic migraine despite being licensed for the condition.

Botox -- a neurotoxin derived from the Clostridium botulinum germ -- works as a cosmetic by paralysing the muscles that cause wrinkles.

It has now been authorised in Britain, the United States and elsewhere to relieve chronic migraines, administered by regular injections to up to 39 sites in the head and neck muscles.

But the British journal Drug and Therapeutics Bulletin said clinical trials showed only "limited evidence of benefit."

Between one and 10 percent of volunteers who were injected with the drug experienced uncomfortable or painful side effects, including muscle spasms, rashes and itches.

The report added it was impossible to completely rule out other risks from Botox, including the risk of infection from a protein called human serum albumin, which is part of the drug's formula.

If Botox has shown only limited evidence of benefit in clinical trials, how come it has been authorized in Britain, the United States and elsewhere to relieve chronic migraines? This should not be! If a drug or treatment is not that effective in trials, it should not be used.
