Many of us take less trouble researching prescription drugs than we would buying a new TV. When it comes to your health doing some research will help you know if you are taking the right drugs and if they really work for your ailments.

Doctors can answer differently too. Following concerns about one drug in the States, the number of prescriptions halved within a year. Here in the UK, however, where far less coverage was given to the problem, prescription numbers actually went up. Because Americans do have to pay for their drugs, the amount of information available over there from sources like Congressional hearings and court cases is much greater. So here are some recent findings about five commonly prescribed types of drugs that you probably won’t be told about and you might want to consider when weighing up whether to go down the drugs or the nutritional route.

Diabetes drugs – Avandia (rosiglitazone) Avandia is one of a class known as thiazolidinediones that has a history of problems, including weight gain, heart problems and liver failure. The other is Actos (pioglitazone). About 2 million prescriptions are made out for these drugs in England every year. Doctors are keen on them because they are effective at controlling blood sugar, but at what cost?

Eighteen months ago a study found that Avandia raised the risk of heart disease. [1] A few months later, another found it increased heart attacks but not the chances of dying from one. [2] In the States, as a result, Avandia prescriptions dived sharply. In the UK, however, the drugs watchdog – the Medicines and Healthcare products Regulatory Agency (MHRA) – asserted that all was well and prescriptions have actually risen. Further studies didn’t always find the risk. However, some local bodies have come out against Avandia, including the UK Midlands Therapeutics Review and Advisory Committee (MTRAC) who don’t recommend either Avandia or Actos,[3] consultants in the Greater Glasgow and Clyde area are not giving Avandia to any new patients,[4] and the National Institute for Health and Clinical Excellence (NICE), which offers guidance to healthcare professionals, has warned about the increased heart attack risk. [5] And in the last few months, two more serious problems with Avandia have been identified – liver failure and bone fracture.

The excellent American consumer watchdog Public Citizen has called for the drug’s withdrawal after identifying 14 cases of liver failure on the official FDA Adverse Events Reporting System (AERS) database.[6] Then a study found that use of thiazolidinediones for more than one year can double the risk of bone fractures in women &......
