Diphenhydramine is a potent antimuscarinic (a competitive antagonist of muscarinic acetylcholine receptors) and, as such, at high doses can cause anticholinergic syndrome. [69] The utility of diphenhydramine as an antiparkinson agent is the result of its blocking properties on the muscarinic acetylcholine receptors in the brain.
The evidence does not report how antihistamines affect women differently than men. [1] Different studies have reported on antihistamine use in children, with various studies finding evidence that certain antihistamines could be used by children 2 years of age, and other drugs being safer for younger or older children.

Here's More Evidence That Common Drugs May Cause Cognition Issues. If you've ever popped a Benadryl or two to sleep through a long flight (or even just a regular night), you can pretty much count ...
Some elements of the cholinergic crisis can be reversed with antimuscarinic drugs like atropine or diphenhydramine, but the most dangerous effect - respiratory depression, cannot. [ 6 ] The neuromuscular junction, where the brain communicates with muscles (like the diaphragm , the main breathing muscle), works by acetylcholine activating ...
H 1-antihistamines can be administered topically (through the skin, nose, or eyes) or systemically, based on the nature of the allergic condition. The authors of the American College of Chest Physicians Updates on Cough Guidelines (2006) recommend that, for cough associated with the common cold, first-generation antihistamine-decongestants are ...
Conversely, hypertension or tachycardia can be treated with short-acting antihypertensive drugs such as nitroprusside or esmolol; longer acting drugs such as propranolol should be avoided as they may lead to hypotension and shock. [6] The cause of serotonin toxicity or accumulation is an important factor in determining the course of treatment.
As a side effect of medicines or recreational drugs, hypoventilation may become potentially life-threatening.Many different central nervous system (CNS) depressant drugs such as ethanol, benzodiazepines, barbiturates, GHB, sedatives, and opioids produce respiratory depression when taken in large or excessive doses, or mixed with other depressants.
