Question 1

is it safe to take two types of antihistamines togeather ?

Accepted Answer

Probably not: It is not a good idea because of the increased risk of side effects from taking multiple similar meds.

Question 2

is it ok to take any type of antihistamines when already taking acamprosate?

Accepted Answer

Yes: but why? is it because a side effect of the drug, like itching? if so, better stop the Acamprosate and call/see your doctor, wish you well

Question 3

is it ok to take multiple types of antihistamines within a 24-hour period? nothing seems to work as long as advertised.

Accepted Answer

DETAILS?????: What are you treating? Which antihistamines? How many of each? There are easy answers after the details are given. No answer is possible without this information. For chronic urticaria I may manage it with 10 or 20mg  cetirizine (Zyrtec) in AM and hydroxyzine at bedtime. I never use Benadryl (diphenhydramine) except as a sleeping pill.

Question 4

how long do 4 hour antihistimines stay in system?

Accepted Answer

Day or so: Medications that last for 4 hours or so are probably completely gone with a day or so.

Question 5

is it ok to take antihistamines with ?

Accepted Answer

With what?: If you are thinking about drinking alcohol, do not do it. Antihistamines might potentiate the effect of alcohol.

Question 6

how long do antihistamines stay in your system?

Accepted Answer

72 hrs: The biologic effects no longer than 72 hours even though the drug may still be detectable for up to a couple of weeks with certain antihistamines.

Question 7

how can i tell if my antihistamines are working?

Accepted Answer

Feeling better?: The symptoms that they are intended to treat improve.

Question 8

is it ok to take three different antihistamines?

Accepted Answer

Possibly OK.: It probably won't hurt you, but you gotta wonder if it is helping you.  I can imagine combinations of a topical antihistamine, a good general non sedating oral antihistamine, and a traditional sedating antihistamine .

Question 9

is it possible to be allergic to all antihistamines?

Accepted Answer

Unlikely: Please define your symptoms from the medications. Theoretically someone can be reacting to a coating on the tablets, but rarely do people react to antihistamines beside the usually sedative side effects.

Question 10

can someone name prescribed antihistamines, not otc.

Accepted Answer

Antihistamines : They are almost all over the counter. The only one that is not yet is one used for deep sedation called hyroxyzine.
