Are There Any Histamine 2 Receptors That Can Be Used Against Histamine Cascade?
most antihistamines are h1 blockers
Detailed Answer:
Hi, thanks for using healthcare magic
There was histamine 1 (h 1 ) and histamine ( h2 ) receptors and medications that block both.
The histamine 2 receptors are most commonly in the stomach but in persons with very severe allergies or urticaria, who do not respond to the normal meds, these are added to completely block the action of histamine in the body. Eg pepcid, zantac (used in non responsive , severe cases)
H1 blockers are the normal antihistamines that are usually available over the counter.
Eg benadryl, allegra, claritine, .There are even meds used for nausea that block H1 receptors eg dimenhydrinate (dramamine)
In addition to these antihistamines medications such as ketotifen or montelukast can be used.
Ketotifen is an antihistamine and also a mast cell stabiliser (it stops the mast cell from releasing the chemicals that cause the allergic response)
This may be over the counter.
Montelukast is a leukotriene receptor antagonist. Leukotriene plays a role in the allergic response.
I hope this helps, feel free to ask any other questions
I. If one cannot get ahold of one's physician at a given time, and if OTC H1 blockers don't adequately control the histamine response from mast cell activation and/or allergies, is it usually safe for the average person to combine OTC H1 and H2 blockers such as you mention?
II. Are there any effective natural alternative treatments for histamine responses from mast cell activation and/or allergies, such as quercetin, local honey, stinging nettle, or the like?
can be used safely together
Detailed Answer:
HI
Yes, the combination can be used safely
In terms of effective natural remedies, you can use those that you mentioned as well as butterbur extrtract.
Other options would be the nete pot to rinse out your sinuses if congested, the use of filters at home to reduce allergen exposure.
