Adam,
Thanks for the feedback and good question on the children's liquid Benadryl. Yes, swallow what's left. I've taken the tablet form of Benadryl (Diphenhydramine HCL) for over two years during the high pollen count period covering March and April and again in the fall when leaf mold is high. 25 mg in the morning and another 25 mg before bed keeps me CH pain free.
I discovered the Diphenhydramine helped kick start the vitamin D3 and get me back pain free in March of 2015. Our home is situated in an area I carved out of deep woods with lots of large Alder and Maple trees surrounding the house. My black pickup takes a hit in the high pollen count March-April period from Alder and Big Leaf Maple trees.
I'd returned from two weeks travel to find my black pickup truck looking like someone had dumped a bag of Portland cement on it...

I had the obvious symptoms of allergic rhinitis within a few hours of returning home. 12 hours later, the CH beast jumped ugly. A few days loading vitamin D3 at 50,000 IU/day had no effect. Then the clue bird made a low pass... Treat the allergy...
After researching the options and reading a few papers on neurogenic inflammation associated with allergic reactions, I selected Diphenhydramine as a first-generation antihistamine... It worked. Less than 24 hours later, I was again CH pain free.
I started posting about my experience with Benadryl (Diphenhydramine HCL) a few days later and so far, several other CHers who have tried it reported similar favorable results.
I started a burn-down test of my 25(OH)D reserves while fishing in Alaska in August figuring my serum 25(OH)D at 109 ng/mL and the good clean Alaskan air would keep me pain free for at least two weeks or longer. I was wrong. Two days after stopping the vitamin D3 I got hit. Not hard, but hard enough to let me know I had a problem.
I had my basic kit of anti-inflammatory regimen supplements but no Benadryl... Then it dawned on me. We had added a new shed roof to the side of the house a few days earlier and as a part of that process, replaced some siding under the eves that had evidence of water damage. Behind the siding we found 1940s era news papers that had been used as insulation... The newspapers were loaded with dried mold... Two days loading vitamin D3 at 50,000 IU day had little effect. I still got hit once a night.
The small general store in Pelican had no Benadryl tablets but they did have the Children's Allergy Relief liquid Benadryl (Diphenhydramine HCL) so I started it at 12.5 mg (5 mL) twice a day... The second night after starting it, I was again sleeping CH pain free.
Regarding the probiotic... Nearly 70% of our immune system resides in and around the gut. A number of RCTs have found keeping the gut healthy and happy with probiotics can have a beneficial outcome by building a stronger immune system.
I checked clinicaltrials.gov and found 781 studies listing probiotics as a method of intervention for a wide array of medical conditions and diseases. One of these studies is presently enrolling by invitation for the prevention of migraine headache using a probiotic as the intervention.
Regarding your question on how many CHers take longer than 30 days to respond to this regimen, the survey data indicates 10%. Three of the chronic types took two months to respond. This is consistent with over five hears of posts from CHers taking this regimen for the first time and having a similar problem like yours.
After some serious reading, it appears that the process of preventing CH with vitamin D3... and Diphenhydramine HCL, conforms to the law of mass action...
At its most fundamental level, the interaction of a drug or nutrient, in this case, 1,25(OH)2D3, the genetically active metabolite of vitamin D3, with its receptors at the genetic level and Benadryl (Diphenhydramine HCL), follow the law of mass action. That law dictates that:
- The combination of drug (also called ligand) and receptor depends on the concentrations of each
- The amount of drug-receptor complex formed determines the magnitude of the response
- A minimum number of drug-receptor complexes must be formed for a response to be initiated (threshold)
- As drug concentration increases, the number of drug-receptor complexes increases and drug effect increases
- A point will be reached at which all receptors are bound to drug, and therefore no further drug-receptor complexes can be formed and the response does not increase any further (saturation)
There is ample medical evidence that these basic principals of vitamin D3 pharmacokinetics and pharmacodynamics are directly related to the vitamin D3 dose, dosing interval, duration of exposure, the serum concentration of 25(OH)D (both basal and therapeutic level) and the relative density of VDR in target tissues.
That's a long-winded answer to a question you didn't ask directly... What I'm saying... in simple terms... is stick with this regimen... You're doing the right things... It could take a bit longer, but the odds are in your favor it will work.
Take care and please keep us posted,
V/R, Batch
