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. ...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

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

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. ...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

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. ...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?

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 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. ...Read more

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. ...Read more

Can I take Benadryl (diphenhydramine) after claritin?

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 you take Benadryl (diphenhydramine) with claritin?

Yes: There is no interaction. Since Claritin (loratadine) does not cause drowsiness side effects should not be a problem. However, if Claritin (loratadine) is not solving the problem, alternatives such as Allegra or zyrtec should be considered. ...Read more

Can I take Benadryl (diphenhydramine) after taken a claritin?

Can I take Benadryl (diphenhydramine) after taken a claritin?

Not recommended: Claritin is a slow release, non-sedating antihistamine. Benadryl (diphenhydramine) is a faster onset sedating antihistamine. Taking both will have additive effects and possible adverse effects such as sedation. It is not recommended that you take both of these without the guidance of your doctor. If the Claritin is not adequate for your symptoms, there are many other medications that can be prescribed to help. ...Read more

Can you take Benadryl (diphenhydramine) and Claritin together?

Can you take Benadryl (diphenhydramine) and Claritin together?

Antihistamines: They are both antihistamines, so I wouldn't take them together. They both act similarly, so their effect would be too much together. Wait until one wears off before trying the other, about 24 hours or so. ...Read more

Is it safe to take loratadine and Benadryl (diphenhydramine) together?

Depends: They are both in the same family (antihistamines), but a few people have daytime symptoms so take non-sedating med (like loratadine) and its effect wears off before next day's dose, so take a sedating (/older) antihistamine (like benadryl) at bedtime for continued relief and to aid with sleep. If no heart / urinary / blood pressure issues and no other meds to conflict with, not likely a problem. ...Read more

Took Claritin this morning. Can I take Benadryl (diphenhydramine) tonight?

Should be OK!: Good afternoon,
adding one Benadryl (diphenhydramine) for symptom relief in addition to Claritin is acceptable. These drugs act through different mechanisms and should not cause any additive side effects. Benadryl (diphenhydramine) is a sedating antihistamine, which should come handy to fall asleep at night and have a good night's sleep and be ready for action the next day! Good luck. ...Read more

Is it safe to take Benadryl (diphenhydramine) if I took two 10mg loratadine tablets a few hours ago?

Yes: The two are compatible in the short term. Benadryl (diphenhydramine) is potentially sedating, so caution is advised. By the way, studies show the regular adult dose of loritadine is 10 mg and 20 mg is not found to be any more effective. ...Read more

Allergic to benadryl, (diphenhydramine) what else can I take besides claritin?

Can you take a generic Benadryl (diphenhydramine) when you have taken a luqi-gel claritin?

Yes you can: Yes you can occasionally take Benadryl (diphenhydramine) especially at night with Claritin if Claritin alone is not helping your symptoms but I will not recommend taking it for long periods and 3to 4 times a day of benadryl
most of the time try to take one or the other if it works for you or consult your doctor or an allergist. ...Read more

Took claritin 24 hr about 4-5 he's ago but still having sinus symptoms is it OK to take benadryl (diphenhydramine) also?

Won't help: If the problem is still congestion and pressure, antihistamines help mainly the itchy runny nose not the congestion, so you need a decongestant, but make sure your blood pressure is normal before using it, your Doctor would help you in that regard, meanwhile use saline nasal wash frequently, goodluck ...Read more
