some of us have results with blood pressure meds. they seem to prevent ICP spikes by preventing BP spikes.
using Claritin and Zantac together suggests histamine intolerance. you may have a very knowledgeable doc there; most docs are not aware of this problem. my daughter has it and it seems to trigger headaches, and these meds help. I don't know if they are migraines or ICP headaches, to know if these meds are helping ICP.
Namenda blocks glutamate, which can cause brain edema. theoretically this should help. however it made me sedated and I couldn't take it. but everything sedates me so you might be fine with it.
I seemed to have improvement with Progesterone, which has been shown to reduce brain edema. however you don't want to take estrogens.

Nerve block anyone?

I have tried namenda the trial pack ,my memory got worse so we decided to go off that.Ive done the 3 rounds of botex and no luck.Dr wants me to do another round of it but insurance says no and with all my medical bills im not adding another one. I also was on diamox it made me feel so crappy and weak so we tried 3 different times diamox in different form i,e, pills sequals.No luck i have a lp shunt but its tied off and just got a vp shunt june 28th i had low pressure headaches even though it was a programmable shunt im getting used to it so if you need any advice im here to help ! Best of luck oh and if u have a dr that says anything below 30 is low find a new dr.:)

I am on Candesartan to help with IIH symptoms. I suffer with terrible vestibular problems (migraines). Is anyone else on a blood pressure RX to help with IIH? My doctor said Candesartan can help. She has even used it for folks who have lowish blood pressure to help with the symptoms. My blood pressure is normal but a high normal.

My nausea is still present but stepped down and much less volatile. My recovery from bouts of extreme nausea are quicker. Four years of being sea sick is too long. This is a welcome break.

I have never heard of iih being treated with anything other than diamox or topomax. I havemaxed out on topomax and can't tolerate Diamox. Can someone explain how these medication work for iih and when they would be prescribed. My dr keeps saying my only option is a shunt which I don't want and ''my vision isn't bad enough''. I wonder why dr doesn't know about these, she's supposed to be really good for iih and always consults with the neuron department if the hospital.

I haven't seen any docs who use these for IIH or talk about it. but from my own experience, the blood pressure meds seem to block a spike in BP that can increase ICP. it's more for people who have fluctuating ICP with a fairly normal baseline, I guess. the only thing that dropped my baseline was treating sleep apnea. and my sleep apnea was so mild that the local labs couldn't find it.

I am just about to start on Candesartan to help with my IIH after maxing out topiramate and being on amitriptyline, after having my shunt removed after it being infected. Hopefully this one works

How much Topirimate are you on that you are considered to be maxed out? I am taking 400 mgs (200 twice a day) I never heard of anyone taking that much and all the drs and pharmacists comment how it is a lot. I am now taking 75 mg of Amitriptyline for what my drs insist are post PTC chronic headaches but I think I still get elevated icp with hormonal fluctuations, I have classic PTC symptoms minus papilledema. I might end up having another LP this month to see if my symptoms are caused by PTC or not.

I've been on diamox, and the topamax, and both of them only helped for a little while. With the diamox, I did a trial for it and I was on an outrageous amount. All it really did was make me extremely fatigued, and gave me really bad indigestion. I opted for the VP shunt, because I couldn't handle the meds anymore. The shunt has been amazing, it took a little while to get used to, but I don't remember it's there most of the time unless I bump it on something.

I suffer from chronic migraines, which is very hard to get under control. I have low blood pressure is normal for me, so going on preventatives was hard for me. I take a blood pressure medicine, proprananol, and it helps keep my headache intensity on the lower end of the spectrum. I also take a medicine divalproex, which helps with mood and migraine, and it has helped with intensity as well. I have tried so many different meds to help with them, but it is really hard to find a long term one that will get rid of the bad ones. I still have a daily headache, but as for the ICP those headaches are gone. I have found Ibuprofen gives me a over medicated headache, so I don't take anything with Ibuprofen unless I have to. I used to take Amitriptyline, but it didn't help much. Blood pressure meds help for ICP and for migraines, especially for women at that time of the month. Anything can spike your blood pressure, which will then increase the ICP and migraines. I would definitely give the BP meds a try for a little relief at least.

Keep track of things you have tried because you might find out years down the road that those worked better later than what you thought they did at the time. I am now at a cross road to getting more help with the migraines and I can't remember for the life of me, what medicines I took for what headaches, and which ones worked better than the others. Dr's will also tell you not to google for symptoms and stuff like that, because they don't want you to think that there is something that might not be for your specific case, but it is really good to do as much research as possible. Also look at other cultures for their remedies, you will be amazed at what you could find, and also things that might help.
