Is loratadine like benadryl (diphenhydramine)?

Kinda mostly: Loratadine is a 'non-sedating antihistamine, ' and Diphenhydramine (/benadryl) is a sedating antihistamine (aka: older / h1 & h2 blocker), so yes, they are close cousins in intended effects--just differ in side effects. ...Read more

Can Claritin (loratadine) non-drowsy antihistamine still cause drowsiness?

Yes: Claritin is a second generation antihistamine which causes much less drowsiness than first generation antihistamine, like benadryl (diphenhydramine).

I have plenty of patients who feel drowsy on claritin, especially petite women. ...Read more

Cani take Benadryl (diphenhydramine) with loratadine?

Probably yes.: Many people report their 'daily' non-sedating antihistamine in the am does not provide relief until next am. So, if no concerns for gu/heart/bp/med-conflict issues, then they often take a 'sedating' antihistamine at night for continued symptom relief and 'bonus' of sleep aid effect. ...Read more

Claritin versus Benadryl (diphenhydramine) for kids?

Claritin versus Benadryl (diphenhydramine) for kids?

Work differently: Claritin in a non-drowsy antihistamine. It doesn't cause sleepiness, but you need to use it every day for it to work really well. It's lousy for severe allergic reactions because it takes days to be fully effective. Benadryl (diphenhydramine) causes drowsiness and only lasts for six hours, but is great for severe allergic reactions and works very quickly. If you're exposed and need help now, Benadryl (diphenhydramine) is better. ...Read more

Can childrens allegra be taken with benadryl (diphenhydramine)?

Not a good idea.: Without precise close coordination with a pediatric allergist or knowledgeable pediatrician, taking Allegra and Benadryl (diphenhydramine) together is probably not a good idea. If your child's allergies are that severe, maybe you should address this issue with your pediatrician. Perhaps allergy testing is in order to identify the source of such overwhelming allergy symptoms that requires double dosing with 2 meds. ...Read more
