Question 1

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 2

is doxepin a type 2 antihistamine?

Accepted Answer

Strong antihistamine: Doxepin is an effective but sedating tricyclic antidepressant. This drug's sedating effect is significantly due to its powerful antihistamine effects. Most recently it has been marketed at lower dosages as a sleep medication.

Question 3

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 4

itching in different body parts unrelated to food or indoor/outdoor areas. this might sit for few hours and sometimes i take antihistamines. ?

Accepted Answer

Allergy: The symptoms of itching could be related to an allergy.  You may have to make a diary of what might cause the symptoms and visit a physician.  You could have an allergy to certain clothing dyes, detergents, soaps or tiny insects to name a few.  Dry skin could also be an issue.

Question 5

how many weeks does it take for claritin (loratadine) 10mg to work? how long should i give it a try before deciding to switch to a different antihistamine?

Accepted Answer

A few hours: Claritin (loratadine) should start working within a couple of  hours. If it doesn't not help at all, then switching to another won't do you much good. If it does help somewhat, then you may try the other alternatives which may possess more antihistamine effect than Claritin (loratadine).

Question 6

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 7

is it possible to be allergic to all antihistamines (hives)? i see hives 90mins after taking 3 different antihit's on different days.

Accepted Answer

See a dermatologist: Why taking antihistamine? When you see the dr be prepared to name all antihistamines tried. Exact names. It is possible but very unlikely to get hives from antihistamines: they are used to stop hives.

Question 8

i have two different antihistamines...one is hydroxyzine and the other is is diphenhydramine..which one will cause me to gain weight?

Accepted Answer

Hydroxyzine: Increase in weight and appetite are known side effects of hydroxyzine.

Question 9

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 10

why are the mg dosage of antihistamines different? allegra is 180mg , claritin (loratadine) is 5mg , and zyrtec is 10mg.

Accepted Answer

Potency: Although the doses are not equal they are equivalent in potency. That is the drugs will have equal efficacy at controlling congestion, runny nose etc. The doses are different because they are different compounds and those compounds are of different weight and size.
