Question 1

what are the effects of histamine usually?

Accepted Answer

Lots of effects: Histamine is a chemical that is ordinarily present in different types of cells in the body.  It has multiple effects on blood vessels, glands and nerves and the symptoms depend on whether the histamine is released locally or throughout the body.  In the nose, causes sneezing, itching and runny nose.  In the skin causes swelling and itching and redness.

Question 2

does chantix release histamine?

Accepted Answer

Not that I know of: it acts on nicotine subreceptors (alpha2beta4 as I remember), and does not release histamine.  I see you have a mast cell disorder, so you should be running this by the allerist/immunologist or rheumatologist you are seeing for that condition.

Question 3

is histamine excitatory or inhibitory?

Accepted Answer

Excitatory: Histamine is actually classified as an excitatory neurotransmitter in the brain responsible for the sleep wake cycle.  Too much of it can keep you awake.  That is why it is used in many commercial sleep aides seen with the letters "pm" attached to some kind of pain killer.  A common side-effect of a histamine blocker like Diphenhydramine (benadryl) is drowsiness.

Question 4

does excitement cause histamine release?

Accepted Answer

Not usually, but....: The field of psychoneuroimmunology taught us that our immune response can be activated by suggestion -- for example, developing some allergy symptoms when seeing just a picture of a cat (for someone with a severe allergy to cat dander). Typically, histamine is released by mast cells in the presence of antigen-antibody complexes containing  antigens interpreted by the immune system as foreign.

Question 5

what is the proper dosage of anti-histamine?

Accepted Answer

Package instructions: The package instructions will give the recommended dosages for over the counter medication.  Prescriptions will give the proper dosing of antihistamines and other medications.  Usual dosing takes into account other medications you might be taking plus a margin of safety.  When in doubt, ask your physician.

Question 6

how many anti histamines can you take daily?

Accepted Answer

Diphenhydramine: 300 mg/day from all sources, 50 mg in one dose q 6 hours, it is the most widely used OTC. Other OTC  2nd generation antihistamines  as cetirizine , loratadine or fexofenadine have different dosing but can be taken once a day, and do not develop tolerance, as the case with diphenhydramine, with prolonged usage. Don&#x27;t combine different types unless you ask a physician, wish you wellness
