Question 1

why do antihistamines make me have severe anger?  the pills only contain the antihistamine...nothing else..they do not contain pseudoephedrine.

Accepted Answer

"Mad as a hatter": You may be sensitive to the anti-cholinergic side effects of anti-histamines.

Question 2

do antihistamines like xyzal (levocetirizine) and acne medications like doxol that contain doxycycline reduce the sexual drive/testosterone in the body ?

Accepted Answer

Xyzal (levocetirizine): Although there are many causes for reduced libido, xyzal (levocetirizine) can potentially cause fatigue and sedation in a small % of people leading to reduced sex drive. Try without it for a couple of days and see if the tiger gets awakened. 
Neither affects testosterone production or effect.

Question 3

how long do 4 hour antihistimines stay in system?

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

Question 4

if someone takes 52 antihistamines, is this something to be concerned about?

Yes: It tells me that this is a risky behavior and likely a suicidal attempt.   Call the psychiatrist or the suicide hotline.

Question 5

are there any prescription antihistamines?

Accepted Answer

A few: Antihistamines have been around for many years & many that used to be prescription are now available over-the-counter. A few antihistamines are still prescription, including some first-generation (sedating) medicines like periactin or palgic as well as second-generation (less-sedating) medicines like xyzal (levocetirizine) and clarinex.

Question 6

are antidepressants potent antihistamines also?

Accepted Answer

Some are, yes.: Looking at receptor inhibition profiles (lab data) we can see that some do indeed block histamine receptors.  Older ones in the tca class (elavil, anafranil, etc), trazodone and even a more modern one like Remeron (mirtazapine) do so which can lead to increased sleepiness and appetite.  As far as potency, they're not as effective as sudafed in fighting a cold.

Accepted Answer

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

Question 8

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 9

Accepted Answer

Sosometimes: Sometimes they will help with itch.

Question 10

what are the side effects of using antihistamines?

Accepted Answer

Few: There are no long term adverse effects from using antihistamines.  Short term sides effects are typically from older antihistamines such as Benadryl (diphenhydramine) that can cause drowsiness and delayed reaction time.  New generation antihistamines such as claritin, clarinex, zyrtec, xyzal and Allegra are generally very well tolerated. No dependence  and few if any drug interactions.
