Dr Eggleton said treatment options were available for sufferers, but anti-depressants helped some people who were struggling to function.
"When someone comes in who's feeling low, the GP undertakes an assessment of them. If someone is mildly depressed, an anti-depressant is not your firstline choice," he said. "
But Whangarei mother Deb Williams, who co-founded Community Action on Suicide Prevention, Education and Research (CASPER) after her daughter Cloudy committed suicide, believed increased use of anti-depressants was doing more harm than good.
"The prescribing of anti-depressants doesn't help deal with the causes of the problems that make people depressed or feeling suicidal, they don't help the real condition," Ms Williams said. "What's driving depression and suicides are things like unemployment, poverty, sexual and domestic abuse, poor housing, all things we lead the way at.
"When you take anti-depressants you find you may not sleep then will need sleeping pills, and they will have other side effects that will then need other drugs to treat. They are a mask, just covering over the real problems and issues until something blows."
