Melatonin levels vary greatly from bottle to bottle

The amount of melatonin in dietary supplements promoted to help regulate sleep and wake cycles varies dramatically from 83 percent less than the concentration declared on the product’s label to 478 percent more, with lot-to-lot variations of as much as 465 percent, according to a new study published in the Journal of Clinical Sleep Medicine. “We found that some products have much more melatonin than is indicated on the label,” said study co-author Praveen K. Saxena, PhD, professor in the department of plant agriculture and the Gosling Research Institute for Plant Preservation at the University of Guelph in Ontario, Canada. ... Read More

Boys with autism more likely to have been exposed to SSRIs in womb

Boys born to women who took a type of antidepressant during pregnancy were three times more likely to be diagnosed with autism than boys who were not exposed to the drugs in utero, a new study has found. The greatest risk was in boys who were exposed to the drugs during the mother’s first trimester of pregnancy. Researchers also found boys exposed to these antidepressants were more likely to have developmental delays. The new study, published this week online and in the May issue of the journal Pediatrics, focused on a commonly prescribed class of antidepressants known as selective serotonin ... Read More

FDA rejects another drug aimed at increasing female libido

The decades-long search for a female equivalent to the libido-boosting drug Viagra for men will not be filled any time soon. The latest drug candidate, Sprout Pharmaceuticals’ filbanserin, was rejected by the Food and Drug Administration (FDA).

Developing drugs to boost female sexual desire is a complicated science because the root cause can be multifaceted – such as psychological – and thus harder to understand and measure. “And, quite honestly, we don’t know enough about ...

SSRIs, SNRIs could ease symptoms for fibromyalgia sufferers

Antidepressants may offer relief for people who suffer with fibromyalgia. Fibromyalgia is a chronic central hypersensitivity syndrome, which occurs when the central nervous system becomes hypersensitive to different stimulus. This results in patients reporting a variety of symptoms including muscle pain, headaches, irritable bowel syndrome and chronic fatigue. Studies suggest that central hypersensitivity is mainly caused by an imbalance of neurotransmitters such as serotonin and norepinephrine, which work to keep pain sensation and mood in balance. When levels of serotonin or norepinephrine are out of balance, which occurs with fibromyalgia and depression, the brain cannot properly process pain signals, exaggerating one’s ... Read More

Should you take antidepressants while pregnant?

Feeling depressed when pregnant goes against the ultimate joy society tells us we should feel when carrying a child. But many pregnant women – including some with no prior history of the condition – will get the blues. Deciding whether to take medication to treat the symptoms of depression during pregnancy is a difficult one to face. When women become pregnant, the level of the female hormone progesterone dramatically increases. For some women, it can also increase the level of an enzyme that breaks down serotonin, a neurotransmitter that regulates mood, causing symptoms of depression. Numerous studies have estimated that ... Read More
