Hello docs. I was wondering can you take Claritin and Benadryl (diphenhydramine) at the same time?

Hello docs. I was wondering can you take Claritin and Benadryl (diphenhydramine) at the same time?

Preferably no: Claritin should last approximately 24 hours, Benadryl (diphenhydramine) last about 3-4 hours. For usually treatment of allergic rhinitis or general allergy control most people do not need to take both at the same time. There are some circumstances where both may be taken on the same day but you should be followed and directed by an allergist if you are using so much antihistamines to control your symptoms.

Is it ok for child to take Claritin and Benadryl (diphenhydramine) at the same time?

Is it ok for child to take Claritin and Benadryl (diphenhydramine) at the same time?

Yes, but: Yes, but why would they? They are both antihistamines and therefore do the same job.

Can I take Benadryl (diphenhydramine) and Claritin at the same time?

Can I take Benadryl (diphenhydramine) and Claritin at the same time?

Yes: Antihistamine is safe even with 4x the average daily dose. The major side effects would be dry mouth and drowsiness (the latter much less common if one uses the non-sedating type). I believe reactine is equivalent to Claritin (loratadine) in the us. Short answer- it is ok.

Can my 8 yr old child who has heart disease take Benadryl (diphenhydramine) and Claritin at the same time?

Can my 8 yr old child who has heart disease take Benadryl (diphenhydramine) and Claritin at the same time?

Overdoing It: No. Please do not do this. There is so much evidence in medicine that more is not better. One should not mix medications that are similar in nature unless instructed to do so by a doctor. One does not give a child both Benadryl (diphenhydramine) and Claritin at the same time.

Can I take diphenhydramine and loratadine at the same time?

Can I take diphenhydramine and loratadine at the same time?

Yes: Taking Loratadine in the morning and Diphenhydramine at night will help you avoid the drowsiness side effects of Diphenhydramine and help you if the Loratadine is not controlling your symptoms for the full 24 hours.

Can I take diphenhydramine and loratadine at the same time? Thanks in advance.

Can I take diphenhydramine and loratadine at the same time? Thanks in advance.

Why should you?: Loratadine (Alavert, Claritin) is a mainly non-sedating antihistamine. Diphenhydramine is very sedating and affects the brain if if you don't feel sedated. In severe itching or welts, taking more that the recommended dose of antihistamines is acceptable. I would suggest you double-up on loratadine rather than adding the other and even then only if absolutely necessary.

I took Benadryl at 11 PM for my allergies. Can I take my regular Claritin-D at 11 AM the morning after? Benadryl was a one time thing for night relief

No problem: But do realize that the D in Claritin may raise your blood pressure and may not be good as a long-term medication. Nasal steroid is usually more effective and safer in the long run.

My 3 year old has allergies which I treat with Claritin, but now he has hives on his legs! Can I give him Benadryl (diphenhydramine) and Claritin at the same time?

My 3 year old has allergies which I treat with Claritin, but now he has hives on his legs! Can I give him Benadryl (diphenhydramine) and Claritin at the same time?

Yes: Those two medications work very differently on allergies, and it is ok short term for a few days to combine the two if you need to. Also make sure he gets plenty to drink as both of these tend to dry up mucous membranes and he may feel very thirsty.

Can I take Claritin and Benadryl (diphenhydramine) together and drink it down with an alka-seltzer?

Can I take Claritin and Benadryl (diphenhydramine) together and drink it down with an alka-seltzer?

Maybe: Depending on what you are treating, I would space them out, take Claritin in the morning and Benadryl (diphenhydramine) at night. Benadryl (diphenhydramine) is sedating though, so be careful driving or operating machines. Not sure what you are treating though. I can see that with urticaria but for nasal allergies, I would use a nasal spray instead of a second antihistamine. Alka seltzer will only help pain because it has aspirin.

Is Benadryl (diphenhydramine) and Claritin the same?

Is Benadryl (diphenhydramine) and Claritin the same?

No and yes: They are both antihistamines but Benadryl (diphenhydramine) often causes drowsiness but is more effective in drying up the nose. It also has a shorter duration of action than claritin.

Can I take Benadryl (diphenhydramine) after claritin?

2 antihistamines: Even though both Benadryl (diphenhydramine) and Claritin are both antihistamines, there should not be significant interaction or side effects if taken at the usual doses.

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.
