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

Is loratadine like benadryl (diphenhydramine)?

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

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 I take Claritin with benadryl (diphenhydramine)?

Can I take Claritin with benadryl (diphenhydramine)?

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

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

Is Claritin comparable to benadryl (diphenhydramine)?

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. ...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 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 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

Does Claritin work better than benadryl (diphenhydramine)?

Not necessarily: Claritin is non-sedating at 10 mg and is a once daily medication. It has an onset of action approximately 30 minutes after taking. Benadryl (diphenhydramine) tends to work more quickly but lasts only 4-6 hours and can be sedating. ...Read more

Benadryl (diphenhydramine) vs. Claritin. Which one is better?

Depends on reason: Both are antihistamines, both are effective for allergies. Benadryl (diphenhydramine) may be more potent and work better in some individuals, but causes much more sleepiness and the effects wear off more quickly than with claritin. ...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?

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

Can you Claritin and Benadryl (diphenhydramine) be taken together?

Can you Claritin and Benadryl (diphenhydramine) be taken together?

Yes: Most antihistamines are dosed at levels much below the toxic levels. Claritin was initially tested in drug studies at 4 times the current recommended dose. These same studies found that 10 mg yielded nearly equvalent effects as 40 mg. Since there is not a dramatic dose effect, increasing to higher levels rarely improves nasal symptoms. Benadryl (diphenhydramine) may have drying effects but sedation limits the dose. ...Read more

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

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
