Does Claritin do the same job as benadryl (diphenhydramine)?

Does Claritin do the same job as benadryl (diphenhydramine)?

Similar, yes: They are both antihistamine, but Claritin is classified as nondrowsy. Benadryl (diphenhydramine) seems more effective in controlling allergies symptoms, but has more potential to cause drowsiness etc...
So, if your allergy is not too bad, it is reasonable to try claritin. Claritin is once daily comparing with Benadryl (diphenhydramine) 3-4x/day
if this fail, consult your doc for additional treatments etc...
Good luck. ...Read more

Is it possible for me to take Claritin d and Benadryl (diphenhydramine) at the same time?

Is it possible for me to take Claritin d and Benadryl (diphenhydramine) at the same time?

Preferably no: Claritin d should last approximately 24 hours, Benadryl (diphenhydramine) last about 3-4 hours. For 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. ...Read more

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. ...Read more

I gave my 2 yr old benadryl but was given claritin from her pediatrician, is it safe to give both in the same day?

Yes: I usually pick one or the other, but claritin as a good safety profile and few side effects. It does not aggravate the sedation common to benedryl so overlapping them is fine. Benedryl is a bit more effective, but wears off in about 4 hours. Claritin has longer term benefit (a day) but can take a day or two to build its effect. As I said, one or the other in the future. ...Read more

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. ...Read more

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. ...Read more

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. ...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

I took Claritin 24 hours, 12 hours ago but my allergies are out of control again. Can I take half a Benadryl (diphenhydramine) to help with my itchiness?

I took Claritin 24 hours, 12 hours ago but my allergies are out of control again. Can I take half a Benadryl (diphenhydramine) to help with my itchiness?

Yes: Adding Benadryl (diphenhydramine) is fine. If your allergies are out of control you might want to consider adding medicated nasal sprays to your treatment regimen. Consider seeing an Allergist so that you can get better relief. Skin testing to determine sensitivities to indoor and outdoor allergens is useful. If you fail both medications and avoidance measures you might want to consider allergy shots. ...Read more

5 1/2 yr old takes children's Claritin every am but is still plagued with allergic cough - worse at night. Ok to dose with Benadryl (diphenhydramine) in the pm?

Yes: Be sure to speak with your pediatrician or allergy-immunology specialist regarding an appropriate dose for your child's weight. Often times severe allergies are treated with antihistamines alone like claritin/nondrowsy and Benadryl (diphenhydramine) together. Other options are available if Benadryl (diphenhydramine) doesn't work. Sedation and dry mouth are common side effects. Consider saline spray and environmental changes. ...Read more

My doctor put me on loratadine 10mg antihistamine, one tablet every 24 Benadryl (diphenhydramine) after I've already taken loratadine for 2 days now. Is this safe?

Benadryl (diphenhydramine) - no drive: Loratadine rarely causes drowsiness unless taken with medications such as erythromycin, cimetidine or ketoconazole. Benadryl (diphenhydramine) affects our brain even if don't feel sedated. If you absolutely need to take both medications, take loratadine AM and Benadryl before you go to bed. ...Read more

What do you suggest if my doctor put me on loratadine 10mg antihistamine, one tablet every 24 Benadryl (diphenhydramine) after I've already taken loratadine for 2 days now?

Depends on Problem: If you were put on loratadine for allergies and it is not responding to the medication you can take the loratadine in the morning and Benadryl (diphenhydramine) at night. But, there are other allergy medicine that may help you more. I would suggest letting your doctor know you are not getting relief. Also, be careful with Benadryl (diphenhydramine) as it can be sedating and driving with it is a DUI in many states. ...Read more

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

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

Can Benadryl (diphenhydramine) be taken with claritin?

Can Benadryl (diphenhydramine) be taken with claritin?

Zyrtec and Benadryl (diphenhydramine): Hello. These two antihistamines taken together will probably cause sedation. As physicians, we often times double up on antihistamines in challenging cases but I usually use non-sedating antihistamines when I do this. There are other medications that may work better than this combination. Check with your doctor for other options. ...Read more
