Child Took Adult Allegra
Fexofenadine is an antihistamine which is used to treat allergies such as hayfever, and hives. It can be taken once or twice a day. It is a second generation antihistamine and does not cause as much drowsiness as other antihistamines such as Diphenhydramine (benaryl) or chlorpheniramine. Always be careful about drowsiness with any antihistamine especially if driving ...Read more
Can i give my child children's Benadryl (diphenhydramine) if they had children's Claritin earlier?
No: Both are antihistamines, and the Claritin is very long acting (12-24 hours), so the Benadryl (diphenhydramine) would be a double dose of similar drugs and likely cause increased side effects--sleepiness, irritability, dry mouth or behavior change. You should wait 12-24 hours to give the benadryl (diphenhydramine). ...Read more
Sure: Plain Children's Benadryl and plain Adult's Benadryl have the same diphenhydramine ingredient. One just has to decide how many milligrams to take (such as 25mg or 50mg), and then she can figure out how many tablets, capsules, or milliliters of the Children's or of the Adult's formulation to take. If one takes the same number of milligrams, it should not matter which formulation is taken. ...Read more

A pediatrician recommended Benadryl (diphenhydramine) for my toddler's cold. is allegra similar? 24lbs
Yes and no: Benadryl (diphenhydramine) is a sedating antihistamine. Allegra is a non-sedating antihistamine. How old is your child? Typically you should not use these meds on children less than 2 yrs old. There are other things you can try such as bed elevation and humidifier at night. ...Read moreSee 2 more doctor answers

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.

My husband and i accidentally gave our 4 yr old son, who weighs 42lbs, a double dose of childrens benadryl (diphenhydramine) for his allergies (chewable tablets 12.5mg)?
??no numbers??: The only way for me to comment on the dose is if you list what you gave. Two 12.5 mg tabs in a 42 lb kid might make him groggy but shouldn't hurt in the long run.Four tabs would put him to sleep and he'd be out for a few hours. Luckily the med clears the body in 4-8 hours. ...Read more
I gave my children children Claritin at 6:00 am and just gave them children Benadryl (diphenhydramine) at 8:00 pm. Should i we worried?
Antihistamines: Assuming the doses of Claritin & Benadryl (diphenhydramine) were right for each child's age/weight, only possible concern might be sedation (even though Claritin is promoted as non-sedating. Each drug works on a different antihistamine receptor, so there shouldn't be any interactions, just improved symptom relief. Also, giving the med's 12+ hours apart decreases likelihood of any problems. ...Read more
I gave 3/4 table spoon of children's Benadryl (diphenhydramine) to 5 year, 9 month old son. Will he be ok?
Ped recommended giving 1/2 TSP of Children's Benadryl (diphenhydramine) to 22mo. I gave it to her then realized it was Children's Benadryl (diphenhydramine) PLUS Congestion. OK or NO!
Benadryl (diphenhydramine) syrup : These medications sre not recommended for children under 2 years, the American Academy of pediatrics does not recommend them even for kids under 6 years, 1 dose is not going to cause any problem, if that was given to treat nasal congestion, just use saline nose drops, they are safe and effective. Good luck. ...Read more

Get testing: Puffy eyes in a child is sometimes allergic but sometimes not. If the allergy medication is failing, I would revisit your child's doctor and get tested for other conditions. Kidney disease, for example, can cause puffy eyes in kids, without redness or itching. Hope this helps. ...Read more
Got itchy red bumps only in the areas I applied Johnsons baby oil. Taking allegra 180mg in the day & Benadryl (diphenhydramine) 25mg at night. When will rash go away?
Soon: It sounds like you've had a contact dermatitis/allergy reaction to the baby oil. Unfortunately, that specific baby oil contains an ingredient that metabolizes into formaldehyde, a toxic chemical that can trigger reactions like yours. The Allegra (fexofenadine) will help, but topical Hydrocortisone found over-the-counter will likely help even more. I'd apply it twice daily. ...Read more
Itchy bleeding nostrils, itchy eyes and body. For 6 weeks. Claritin allegra Benadryl (diphenhydramine) don't work. My baby now having similar symptoms plus a rash.
Avoid doing this: Allegra (fexofenadine) is sold in both 60 mg doses taken twice a day, and a 180 mg dose taken once a day. There is not good data on taking twice the dose at one time. Avoid doing it. If your allergy symptoms are not controlled with the fda recommended dosing, see an allergist. There are certain situations when i prescribe other dosing. ...Read more
No major problem: If this is a plain antihistamine with no decongestant in it,I would expect no serious problem although some minor drowsiness may occur. As,long as you're experiencing no discomfort simply let the medication dissipate. If you have any further concerns, call your physician. ...Read moreSee 2 more doctor answers
Probably not much: If they were 30 or 60 mg then probably not much. Not sure about 180 mg. Suggest contacting poison control center in your area. The more important question is why you took four. Not to assume anything but if it were intentional in an attempt to harm yourself then seek someone's help now. ...Read more
Probably: If stored in cool area , it is likely ok for 2 more years after the expiration date . The US Army did a study on that and found that most drugs were good for a couple more years after the stated expiration date if stored properly. In Allegra's case, the worst would be less effectiveness. However I would caution using antibiotics, biologicals (insulin etc), and epinephrine past the expiration date ...Read more
I accidently took two allegra (fexofenadine) today, one this am, one just now. Should I be worried?
Be happy: You did not mention what strength of Allegra (fexofenadine) you took, but i assume you are worried because you took 2 tablets of 180mg each. We use this dose quite often for patients with severe rashes or hives. Also, during the clinical studies prior to the release of allegra, (fexofenadine) doses of up to 540mg were used without ill effects. ...Read moreSee 1 more doctor answer

Medication overdoses: Normally just taking one extra Allegra (fexofenadine) too soon is not going to cause problems. however if you get any severe headache, palpitations, or dizziness call your doctor right away. If you have any chronic heart or blood pressure issues you might want to check your blood pressure today if possible. If it's too high call your doctor. ...Read more
I took Allegra (fexofenadine) that expired 1/2015 today should I be concerned or what symptoms would require seeking medical help?
Many dayquils: Unfortunately there are several formulations under the DayQuil name. If it contains phenylephrine then it's not so good to mix with the "D" in Allegra-D because it contains pseudoephedrine. Those are both stimulant decongestants and can cause rapid heart beat, elevated blood pressure and nervous side effects. ...Read more
