Sedating anti histamine ohio valley dating
When you get injured or your immune system detects a potentially dangerous foreign substance, certain white blood cells and tissue cells release histamines that seek out and attach to other cells that have a histamine receptor.
Here, the histamines induce an inflammatory response — they dilate the blood vessels, increasing blood flow to the site of injury or invasion.
All medicines have possible side-effects, though you may not necessarily experience any.
Side-effects from antihistamines are more likely to occur in children and the elderly, and some of the most common ones associated with this type of medicine are listed below.
This is often referred to as an 'itch-scratch-itch' cycle.
Antihistamines may cause side effects that could worsen conditions, such as glaucoma, enlarged prostate gland, retention of urine, or obstruction of the gut, and for this reason they should be used with caution in these conditions.In these conditions they work by preventing the actions of histamine, which is a substance produced by the body as part of its natural defences.It's stored in cells called mast cells, in almost all tissues of the body, and is released when the body reacts to a foreign substance (known as an allergen).Drinking alcohol with a sedating antihistamine can increase the drowsiness it causes and should be avoided.Also beware of a 'hangover' effect in the morning if the tablets are taken too late at night.
