There are growing fears about serious side-effects from two popular contraceptive devices on the market.

An ABC investigation has found women around the country are reporting serious concerns about the Implanon hormonal arm implant and Mirena intra-uterine devices.

Their concerns include chronic pain, pelvic inflammatory disease, serious scarring and depression.

More than 945,000 Implanon devices were inserted in Australia over the past decade, and of those the Therapeutic Goods Administration has received more than 1,000 reports from treating doctors and specialists of side-effects and other problems.

These include more than 500 unintended pregnancies, more than 50 vaginal haemorrhages and 27 ectopic pregnancies.

With more than 967,000 Mirenas implanted in the past decade the Therapeutic Goods Administration has received more than 850 reports of adverse effects.

These include 70 pregnancies and more than 100 uterus perforations.

In a statement Bayer, the makers of Mirena, said millions of women worldwide had used the device, “But like any prescription product, Mirena has risks and benefits”.

“We investigate reports on side-effects thoroughly and collaborate closely with the Therapeutic Goods Administration concerning the use, benefits and risks of all products,” a spokeswoman said.

The ABC reported that the Royal Australian New Zealand College of Obstetricians and Gynaecologists said the side-effects reported by women were “not typical”.

Dr Amber Moore from the college said women with Implanon should only get a tiny scar similar to a vaccination scar.

“They provide a great deal of a certainty for women in terms of safety against pregnancy, and they’re incredibly cost-effective,” she said.

“After the first few months … most women will in fact end up never going through another packet of pads or tampons.

“All the studies internationally and here have indicated that women like them because they go back in, they have another one.”

In June a new study suggested birth control pills could have more dangerous side effects than previously thought. Read more on that HERE.
