Non sedating antihistamines in children
People with chronic medical conditions like kidney disease may need less frequent doses because the drug may take longer for them to process.Older adults and adults who have chronic illness should only take 5 mg of Zyrtec per day.Zyrtec and Claritin are both priced about the same.They’re available over the counter, so prescription drug insurance will likely not cover any portion of their expense.For that reason, you shouldn’t take these medications if you also take muscle relaxers, sleeping pills, or other drugs that cause drowsiness.Taking them at the same time that you take sedating drugs can make you extremely sleepy.
Children this age using Zyrtec should be given 2.5–5 mg.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.The dosage depends on your age and the severity of your symptoms.Claritin is active in the body for at least 24 hours.
