Dr. Jim Kennedy, of the Royal College of General Practitioners, head of prescribing, notes that pregnant women are often told not to take many medications without scientific proof of its harm.

Dr. Kennedy worries, according to a BBC report, that women may be risking their health more by not being treated in the best way.

"Women are being denied use of drugs for everything from headaches and depression to infections."

"For some drugs such as statins for cholesterol and some anti-epilepsy drugs, the risk of not taking medicine may be greater than the risk of taking them."
