My friend has a food allergy reaction. We are unable to access Benadryl (diphenhydramine) (in Saudi Arabia). What action can we take? How much Zyrtec can she take?

Look for. diphenhydramine which is the generic of Benadryl. They should know what that is/have it there. If you try Zyrtec, (cetirizine) take 10mg daily. Best of luck! Read more...
2/day. If she has Rash from food allergy, she can take 10 mg of Zyrtec (cetirizine) twice daily. If she has GI upset from food then she should avoid eating any solid food and drink plenty of liquid with electrolytes and stay hydrated. If she is having Respiratory distress, she need to seek the medical advise right away. Hope she feels better soon. Read more...
The recommended dose. Take 10mg daily as is the recommended dose. There are several other anti-histamines other than benadryl (diphenhydramine) that could be prescribed to her if the allergy is severe. Certainly avoid the foods first and foremost. Read more...

My mom is allergic to Benadryl (diphenhydramine) can she us a generic zyrtec?

Maybe, maybe not. These are both antihistamines, just different generation, zyrtec being the younger one. Being allergic to Benadryl (diphenhydramine) is not necessarily meant allergic to zyrtec as well. At times, people misunderstand intolerance vs allergic--people are more often intolerant than allergic. If symptom is mild, she can try zyrtec. If severe, i would consult doc first for eval. Good luck. Read more...

I'm allergic to benadryl, (diphenhydramine) have been since I was little. I stopped breathing and swelled up. What else can I take? Is zyrtec okay?

Allergy to benadryl (diphenhydramine) If you had such a severe reaction years ago to benadryl, (diphenhydramine) you should be under the care of an allergist to help protect you, from other allergy attacks that could be severe. It may be that you reacted to something that was in the Benadryl (diphenhydramine) rather than Benadryl (diphenhydramine) itself. Read more...

Should I take Benadryl (diphenhydramine) or zyrtec for a cat allergy?

Either, though... Zyrtec is approved for animal allergy. Claritin and Allegra approved for seasonal (pollen) allergy, not pets, though certainly they'd work to some degree as well. Benadryl (diphenhydramine) will work; and though a good proportion will get groggy or sleepy, you may be a person who can tolerate it, and could be more effective than Zyrtec. I wouldn't drive on Benadryl (diphenhydramine) though - it slows reaction times. Read more...
Depends. If you only have eye itching, runny nose, or sneezing, either may help but can make you groggy (especially with Benadryl). However if you have asthma or nasal congestion, you are out of luck. If the cat allergy is severe, nothing will work well with continuing exposure and allergy shots may be your best bet.

Is it ok to alternate zyrtec (prescribed) and Benadryl (diphenhydramine) (otc) for a few days for an allergy attack. Would be z in am and b at pm. 17mth old male

Maybe. Zyrtec makes some people sleepy. They basically work the same but Benadryl (diphenhydramine) works for just a few hours and usually causes more sleepiness. May want to try Allegra (otc generic is fine) in morning if zyrtec causes sleepiness. Read more...
Use one-not both. Zyrtec and Benadryl (diphenhydramine) are both antihistamines-drugs of the same class. Either may work better than the other for your son. Zyrtec typically lasts 24 hours between doses. By alternating, you decrease the effectiveness and gain only an additional likelihood of side effects. Even though the Benadryl (diphenhydramine) is otc, stay with it if it works better, and let your doctor know. Read more...
Yes but.... Yes as long as they don't cause drowsiness and thus affecting your alertness. I usually suggest to patients to take something like fexofenadine (allegra) 180 mg during the day and whatever works for them in the evening. Zyrtec causes some drowsiness in slightly over 10% of the people and Benadryl (diphenhydramine) over 30% in my own experience. Read more...
Remember the MOA. As an aside, it's important to remember how these meds work. Your allergies are caused by histamine release in the body. Antihistamines block the release of histamine, not its effects. Its important therefore to take allergy medicine prior to experiencing the allergy symptoms. Antihistamines are to prevent allergy symptoms, not get rid of them once they've already shown up. Read more...
