Will over-the-counter antihistamines like Benadryl (diphenhydramine) have any bad interactions with ssris like zoloft?

Generally no: Second generation antihistamines such as allegra, zyrtec and Claritin are non sedating and do not interact with ssris. Benadryl (diphenhydramine) is sedating and may increase the sedation of ssris. ...Read more

I have welts on my neck after resting my head on a wool pillow. My upper lip is also swollen. I am taking over-the-counter antihistamines.?

Allergy?: Could be an allergy to wool, especially if antihistamines are helping. But hives and swelling could be due to a variety of things including food allergy, medication alley, insect sting, viral infection, or exposure related allergy like the wool.

I was prescribed some antihistamines and over-the-counter decongestants. Is it serious?

I was prescribed some antihistamines and over-the-counter decongestants. Is it serious?

Need More Info: It is probably not serious, but you cannot determine the seriousness of a disease just by knowing the recommended medications. I do not usually give my patients decongestants for long term use due to side effects like insomnia, agitation, elevated blood pressure, and heart rate. They are ok for short term use or when you are sick for a few days. ...Read more

Is there an over-the-counter antihistamine medication available to treat poison oak?

Is there an over-the-counter antihistamine medication available to treat poison oak?

Steroids needed: If you have a significant case of poison oak, antihistamines are unlikely to faze the itching. You probably need oral steroids. You can certainly try oral antihistamines and topical steroids like cortisone 10, but these rarely control the severe itch of even a moderate case. Better see your doctor for stronger stuff. Most cases last about 3 weeks. ...Read more

I currently have a wheat allergy. I was tested for celiac, and it was inconclusive. Is there an over the counter antihistamine I could try?

I currently have a wheat allergy. I was tested for celiac, and it was inconclusive. Is there an over the counter antihistamine I could try?

Hard to say: Wheat is composed of a complex group of proteins and many have selective responses to various components. If you have a simple IgG reaction, it may be of minor importance. If you have TTG-IgA to components of wheat like the gliadin or gluten, your past avoidance of wheat may have made testing unreliable. Continues intake could aggravate issues that antihistamines would not prevent. ...Read more

What is the best allergy treatment for eyes I mean the best eye drops for allergy. Not over-the-counter drugs. Oral antihistamine alone not helping.

What is the best allergy treatment for eyes I mean the best eye drops for allergy. Not over-the-counter drugs. Oral antihistamine alone not helping.

Patanol (olopatadine): I prefer patanol (olopatadine) drops. There are others which are similar. The important thing is to wash your face with a cool wash cloth before applying to remove any lingering allergens from your facial skin and around your eyes. This helps my patients a great deal. If you're not better with drops see an allergist for testing, you may want to consider allergy shots. ...Read more

I have sever hives which continued over 3 weeks so far. What might be the cause (s)? Would telfast or aerius antihistamine meds. Work? Which one better

I have sever hives which continued over 3 weeks so far. What might be the cause (s)? Would telfast or aerius antihistamine meds. Work? Which one better

Hives.: Books are written discussing the many causes of hives. The most common cause would be a reaction to a new medication or food. It is often very hard to find the precise cause without doing an elimination diet and or stopping the inciting medication. Hives can also be caused by viruses, airborne allergies, cold, heat, friction and internal disease. ...Read more

Are antihistamines ever known to bring out the hives they r being taken to prevent? My hives get bumped up within 90mins of any antihistamine.

No: Depending what antihistamine you are taking, they usually take 30 to 45 minutes to start working, your hives do not worsen from them but if you are taking the medicine when the hives have already started, they are not controlling them very well. See an allergist and they can guide your treatment better. ...Read more

When I take antihistamine pills for hives, I get more itchy right after taking the pills before they kick in a few hrs later. Am I allergic to pills?

Be specific: You fail to indicate WHICH antihistamine. All antihistamines need time to see effect. Some are more effective than others. What type of hives, what specific trigger? Allergy to antihistamine is possible but not likely. Vague itching soon after a dose is not a good reason to suspect allergy. ...Read more

I went off antihistamines and 2-3 days later had hives & sudden flushing, hot face. Is it typical to have an effect/backlash like this when stopping?

I went off antihistamines and 2-3 days later had hives & sudden flushing, hot face. Is it typical to have an effect/backlash like this when stopping?

Hives off meds: That is not typical. You may have suppressed an underlying condition which developed while you were taking the allergy medicine for a different reason. If you were taking them for hives, then it just means your condition has not resolved yet. It is common to experience some itching after discontinuation of anti-histamines for a few days but your symptoms sound more than just itching. ...Read more

I've been taking antihistamine meds for some time now, because of my chronic idiopathic hives I'm worry about the side effect & getting immune from it?

Chronic Hives: A number of my patients have been taking high-dose antihistamines for weeks, months, and in some cases even years with little to no side effects. Main side effect can be sedation, otherwise well tolerated. Over time your hives might spontaneously improve so if you have been well controlled for a while now, might be worth attempting a trial wean to see if the hives come back. Talk to your doctor. ...Read more
