"Daily use of SSRIs was also associated with a four per cent reduction in bone mineral density of the hip and 2.4 per cent of the lower spine, the study found."
As more scientists examine the side effects of selective serotonin reuptake inhibitors (SSRIs)--the antidepressants once marketed as "wonder drugs"--the bleaker the picture gets. Rather than "washing away" the blues--as Prozac ads claimed--these drugs are proving to be hazardous to both physical and mental health. The first myth is that SSRIs--in contrast to the old tricyclic antidepressants--are "selective" in targeting an exact neuroreceptor. In fact, these drugs are not selective at all. SSRIs interfere with normal physiological functions causing varying degrees of damage. The latest report by a team of Canadian osteoporosis specialists, published in the current issue of the Archives of Internal Medicine, found that SSRI antidepressants reduce bone density: "Daily use of SSRIs was also associated with a four per cent reduction in bone mineral density of the hip and 2.4 per cent of the lower spine, the study found. The risk of falling was also higher among those taking the pills, which can cause a drop in blood pressure and fainting in some people." The senior investigator, Dr. David Golzman noted that prescriptions for the antidepressants soared by more than 30 per cent between 2000 and 2004. [1] "And that puts a lot of people at increased risk for fractures over and above the risk that they already have as a result of the fact that they're aging and are taking other medication which may also predispose to osteoporosis." If one adds up ALL the risk factors associated with these drugs and weighs those risks against the uncertain (undemonstrated) clinical benefit--as confirmed by the government funded STAR*D study--whose drop out rate is evidence of colossal treatment failure--[2] the risks far outweigh the claimed benefits. [3] It is always astounding to read that a healthcare professional--Dr. Robert P. Heaney (below)--expresses fear that information about drug hazards might lead consumers to decline to take a prescribed drug. Isn't such information the very basis for claiming that one is practicing "evidence-based medicine?" Physicians and consumers must be fully informed about the side effects of prescribed drugs. Lacking knowledge about adverse drug effects they cannot make an informed judgment. References: 1. See: J. Brent Richards, MD; Alexandra Papaioannou, MD, MSc; Jonathan D.

~~~~~~~~~~~ HealthDay Reporter Antidepressants Linked to Fracture Risk Patients should have bone tests before taking SSRIs, study suggests. By Steven Reinberg
MONDAY, Jan. 22 (HealthDay News) -- Men and women in their 50s and older who take antidepressants known as selective serotonin reuptake inhibitors may be doubling their risk of fractures, a new Canadian study suggests. SSRIs, such as Prozac and Paxil, are commonly used to treat depression and anxiety. But previous studies had shown these drugs are associated with an increased risk of fractures from falling. The new research, led by Dr. David Goltzman, a professor of medicine and physiology and director of the McGill Centre for Bone and Periodontal Research at McGill University in Montreal, seems to support the earlier studies. "There is good scientific evidence that serotonin is involved in bone physiology, and if you alter the system, you can get low bone density," Goltzman said. "Patients should be monitored to prevent the risk of fractures." The finding is published in the Jan. 22 issue of the Archives of Internal Medicine. For the study, Goltzman and his colleagues reviewed information on 137 patients -- average age 65 -- who took SSRIs. The patients had their bone mineral density measured at the start of the study and were followed for five years. Each year, the patients were also asked to report any fractures they had and how they occurred. Goltzman's team found these patients had twice the risk of fractures. They were particularly vulnerable to breaks of the forearm, ankle and foot, and less so to fractures of the hip, rib, femur, and back, the study found. Goltzman's group also found that use of SSRIs was associated with an increased risk of falling. The effect depended on the dose of the drug. Doubling the dose resulted in a 1.5-fold increase in the risk of falling. Daily SSRI use was also associated with a 4 percent decrease in bone mineral density at the hip, and a 2.4 percent decrease at the spine, the researchers reported. Patients need to know there's this risk of fractures with SSRIs, Goltzman said. "Patients should not be told not to take SSRIs if they need them for depression," he said. "But this is a new risk that has been identified, and patients should take general steps to prevent osteoporosis. And they should have a bone density measurement before starting SSRIs and periodically after that." But one expert said he thought the study failed to prove that SSRI use is linked to an increased risk of bone breaks. "These findings are hard to interpret," said Dr. Robert P. Heaney, a professor of medicine at the Osteoporosis Research Center at Creighton University in Omaha, Neb. "Increased fracture risk has been associated with depression for years," he added. Heaney said that to really uncover the role SSRIs may play in fractures, a study would have to compare depressed patients taking SSRIs with depressed patients taking other medications. "Then you could see if it was the depression causing the fractures or if it were the SSRIs. It may not be the SSRI at all," he said. Studies like Goltzman's run the risk that people will stop taking their medication, Heaney said. "These kind of studies do some potential harm," he said.

Adults aged 50 and older who take daily doses of such antidepressants as Prozac and Paxil have double the risk of fractures from falls - and it appears that decreased bone mass may be at least part of the reason, a Canadian study suggests. Participants in the McGill University study who had been taking one of five antidepressants from the drug class known as selective serotonin reuptake inhibitors, or SSRIs, had twice the risk of forearm, ankle, hip and other fractures compared with those not prescribed the drugs. Daily use of SSRIs was also associated with a four per cent reduction in bone mineral density of the hip and 2.4 per cent of the lower spine, the study found. The risk of falling was also higher among those taking the pills, which can cause a drop in blood pressure and fainting in some people. "Depression is common in the elderly, and the elderly population is increasing in Canada and most of the Western world," said Dr. David Goltzman, a Montreal endocrinologist and senior author of the study, published Tuesday in the Archives of Internal Medicine. "So depression is increasing as the population ages and the use of SSRIs is increasing at a phenomenal rate," Goltzman said, noting that prescriptions for the medications soared by more than 30 per cent between 2000 and 2004. "And that puts a lot of people at increased risk for fractures over and above the risk that they already have as a result of the fact that they're aging and are taking other medication which may also predispose to osteoporosis." But Goltzman stressed the findings do not mean that people should stop taking the antidepressants. "I think that if they need an SSRI, if their physician feels that they need it to treat their depression . . . they need to be treated with the appropriate medication," he said. "It just means individuals should be aware this is a side-effect and they should probably also take general steps in order to prevent osteoporosis." Those steps include engaging in weight-bearing exercise, eating a diet rich in calcium and vitamin D, and avoiding smoking and alcohol. Goltzman also suggests that older patients should have their bone density tested when they begin taking an SSRI and again after they have been on the drug for a period of time to see if their bones are thinning. Dr. David Healy, an expert in psychopharmacology at the University of Wales College of Medicine, said researchers are finding more and more side-effects associated with SSRIs, which he believes are over-prescribed worldwide. Doctors need to fully explain these side-effects before prescribing the drugs so patients can make an informed choice about taking them, Healy said Monday from Cardiff. The study was funded by the Canadian Institutes of Health Research, several drug companies including Eli Lilly Canada and Merck Frosst Canada, the Dairy Farmers of Canada and the Arthritis Society.
