Side Effects
Piracetam has been found to have very few side effects, and those it has are typically "few, mild, and transient." A large-scale, 12-week trial of high-dose piracetam found no adverse effects occurred in the group taking piracetam as compared to the placebo group. Many other studies have likewise found piracetam to be well tolerated.
Symptoms of general excitability, including anxiety, insomnia, irritability, headache, agitation, nervousness, and tremor, are occasionally reported. Headache from large doses of piracetam may be alleviated by coadministration of an acetylcholine biosynthetic precursor, or a drug with cholinergic effects, such as choline bitartrate, choline citrate, choline alfoscerate, lecithin, cyprodenate or centrophenoxine.

Famous quotes containing the words side and/or effects:
“Each man has his own vocation. The talent is the call. There is one direction in which all space is open to him. He has faculties silently inviting him thither to endless exertion. He is like a ship in the river; he runs against obstructions on every side but one; on that side all obstruction is taken away, and he sweeps serenely over a deepening channel into an infinite sea.”
—Ralph Waldo Emerson (1803–1882)
“Whereas Freud was for the most part concerned with the morbid effects of unconscious repression, Jung was more interested in the manifestations of unconscious expression, first in the dream and eventually in all the more orderly products of religion and art and morals.”
—Lewis Mumford (1895–1990)
