Non sedating antihistamine tablet Pornochat online free iphone
Antihistamines are designed to block the effects of the histamine that your body produces.
In turn, they decrease the symptoms of the allergy.
Levocetirizine is called a non-sedating antihistamine as it does not enter the brain in significant amounts, and is therefore unlikely to cause drowsiness.
However, some people may experience some slight sleepiness, headache, mouth dryness, lightheadedness, vision problems (mainly blurred vision), palpitations and fatigue.
Also available are quick-dissolving tablets, which are marketed as being faster to get into one's circulatory system, but require special handling to avoid degrading in the package.
Patients with severe hepatic (liver) disorders may need to start with a lower dose.
Among the most popular over-the-counter (OTC) allergy meds are Zyrtec and Claritin.
When your body encounters something it’s allergic to, it sends out white blood cells and goes into fight mode. This substance causes many of the symptoms of an allergic reaction.
They both calm your immune system’s reaction to allergens. They also take effect at different times and stay effective for different durations. Antihistamines have a reputation of making you sleepy because the first types crossed into your central nervous system more easily and had a direct effect on your alertness.
These factors could determine which of these two drugs is better for you. However, newer antihistamines like Zyrtec and Claritin are less likely to cause this side effect. Most people experience at least 24 hours of relief after a single dose. People who take it may feel relief in as little as one hour.
non-sedating antihistamine, developed from the second-generation antihistamine cetirizine.
Chemically, levocetirizine is the active enantiomer of cetirizine. Levocetirizine is an inverse agonist that decreases activity at histamine H1 receptors.
