Similar medicines: All of these medicines are antihistamines. Taking combinations of antihistamines increases the possibility of side effects. If antihistamines are not working at recommended doses see a doctor. You may need a different type of treatment for your problem. ...Read more

I have food allergies and if I take benadryl and claritin every day I find I can eat what I want without reacting, is this normal and do others do tha?

Better avoid: Any food (s) that induce symptoms, but you need to define the symptoms, are they itching, rash, hives, shortness of breath that occur within minutes, or maximum hours after ingestion, or otherwise, so you need to keep a food diary. Simply taking an antihistamine and eating what you want may mask the initial warning symptoms. If in doubt, see an allergist, check aaaai. Org or acaai. Org 4 an allergist ...Read more

I have had hives for 3 months. Benadryl, (diphenhydramine) claritin, atarax, zyrtec, chlor-trimeton made things worse. Zantac did not help. What should I do?

I have had hives for 3 months. Benadryl, (diphenhydramine) claritin, atarax, zyrtec, chlor-trimeton made things worse. Zantac did not help. What should I do?

Troublesome problem: Chronic hives are difficult. Your list of medicines is typical and some find that tagomet can provide some relief but you may be better served by seeing an allergist & having some testing done. If you can identify a food or other trigger that you could avoid you might have better luck. ...Read more

Why am I retaining water so much if I don't have kidney or heart issues that I know of? I do take celebrex, silvastatin, benadryl, (diphenhydramine) claritin, which is causi

Why am I retaining water so much if I don't have kidney or heart issues that I know of? I do take celebrex, silvastatin, benadryl, (diphenhydramine) claritin, which is causi

Celebrex (celecoxib): Although less likely than other nsaids in causing sodium retention, Celebrex (celecoxib) is capable of it. Are you consuming a lot of sodium in your diet? If so reducing the intake may help. Some people just tend to retain water for no apparent reason. I hope you are not eating a lot of licorice. ...Read more

Can you tell me for severe allergies like sneezing, what is more effective, allegra, benadryl, (diphenhydramine) claritin, or zyrtec?

Can you tell me for severe allergies like sneezing, what is more effective, allegra, benadryl, (diphenhydramine) claritin, or zyrtec?

Similar, but...: Allegra, Zyrtec and Claritan are all very similar meds and there isn't really one that is better, although one may work better in a certain patient. Benadryl (diphenhydramine) works very differently but has many more side effects than the others, including sedation and need for repeated dosing of the medicine daily. If you feel allergies are ""severe", you need to visit an allergist for more preventative care. ...Read more

I am allergic to shellfish. I just took keflex. I took singulair, benadryl, (diphenhydramine) claritin, Pepcid ac, my ventoltor, I am about to use my epipen.?

Go ahead.: When having a severe allergic reaction Epinephrine is the only medication that can help you immediately with oll your symptoms. Asthma rescue inhalers will only help with your lung symptoms if it gets there. Any swelling in the throat will prevent it from getting there.. H-1 (benadryl (diphenhydramine) and claritin) and h-2 (pepcid) antihistamines and singulair will take up to1hour to work. ...Read more

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

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 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

What are some differences between Benadryl (diphenhydramine) and claritin?

What are some differences between Benadryl (diphenhydramine) and claritin?

Side-effect profile: Benadryl (diphenhydramine) is one of the first generation anti-histamines which cross the blood-brain barrier and therefore causes sedation. It also has a significant drying effect in many patients. Claritin (loratadine) is a second generation and does not cross into the brain and therefore is considered non-sedating. It is usually less drying as well. ...Read more

Any good over-the-counter medicine for red rashes on the body due to food, besides Benadryl (diphenhydramine) or claritin?

Skin Issues: Why would you think that your rashes are allergic in nature and you need an anti-histamine? Rashes can represent significant illness. I would need more information about the rash you are concerned about, but the best option is to be seen by your physician and to find out what your rash represents. ...Read more

Having post nasal drip, cant sleep at night, I should I take Benadryl (diphenhydramine) or claritin? When should I take it, day or night? Thanks.

Drip: If you take a Claritin (loratadine) and the drip stops its allergic. Take the pill between 4to 6 pm (before things bloom) for a couple of days. If there's no change and the drip is worse lying down it could be a symptom of silent acid reflux. You then could try an antacid a few hours before bedtime ...Read more

What can I do about my daughter's (4 y/o) constant nose scratching/digging due to allergies? Is it good to give her benadryl/claritin etc everyday?

Preschooler allergy: Your second question first - no it's not good to give Benadryl (diphenhydramine) multiple times a day, which would be needed to control allergies. Claritin is ok with the guidance of pediatrician or allergist. But it sounds like these are not controlling symptoms. There are other medications, both oral, and most appropriately for her condition, nasal steroid mist. Take time to see allergist and work up a plan! ...Read more

I took benadryl (diphenhydramine) and claritin right before a skin allergy test and was told I was allergic to 4 things. How did they get the results despite this?

I took benadryl (diphenhydramine) and claritin right before a skin allergy test and was told I was allergic to 4 things. How did they get the results despite this?

? False positives: That's why you need to have positive and negative controls in every allergy skin test panel, if the positive control doesn't show any reaction, hence any reaction to any extract applied can be just a local irritation not a true IgE mediated reaction resulting from histamine release. You're better off having a repeat test/second opinion before having a definitive diagnosis and possible immunotherapy ...Read more

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

Inside mu ear is swollen an painful. I also have earwax draining from it. I can't see my dr for a while, will Benadryl (diphenhydramine) or Claritin help?

Probably not...: It sounds like you have an external ear infection, or otitis externa...It is unlikely that this is just an allergic reaction for which antihistamines would work for. I would see a doctor without delay. In some cases, a local infection near or in the ear can spread rapidly. ...Read more

I had an allergic reaction to makeup. My eyes are red swollen and itchy. I have both benadryl (diphenhydramine) and claritin, which would be better to take?

Contact dermatitis: Sounds like you are suffering from allergic contact dermatitis from makeup product. OTC antihistamines can help with itch but the best treatment for contact dermatitis is topical corticosteroid creams. Talk with your doctor and consider scheduling patch testing with an allergist to determine your sensitivities so you can avoid this reaction in the future. ...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

My throat is hurting, how can I tell the difference between an infection and allergies? I take Benadryl (diphenhydramine) and claritin, anything I can take to help me out

Infx vs allergy: Symptoms of allergy vs. Infection can overlap and distinction can be difficult. Allergy symptoms will usually readily improve with Benedryl, Zyrtec, Claritin or nasal sprays, but will often relapse when the medication has worn off. Infections are generally associated with more fatigue, achiness, fever and colored nasal discharge of sputum from cough. ...Read more

If it persists seeDr: Not likely to be allergy causing your sore throat. More likely a mild viral infection (common cold). Some colds are severe with sore throat, nasal and sinus congestion and deep cough. Others are mild and may just cause a mild sore throat. Signs of Strep: high fever, pussy white exudate on tonsils, tender lymph nodes neck and NO cough. If only 2 of these strep unlikely; 4 highly likely ...Read more
