Antihistamines aren't only used for allergies, however.
Some are more commonly used to treat nausea and vomiting, such as Cyclizine (the main ingredient in Valoid), while others are prescribed to patients battling with insomnia, or as an appetite stimulant.
Second generation antihistamines have been investigated for both efficacy and safety in paediatrics.
An optimal understanding of their effects and pharmacology are required for optimal use in each patient.
For this reason, it's best to give the dose in the evening.
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.
It's no wonder we are so ready to reach for the antihistamines: these easily available medicines can do wonders to relieve runny noses, irritated eyes and itchy skins.
But are these medications really safe for our kids?
