Update: we met with the cardiologist today. She has put through a referral for an urgent CT angiogram but is worried it might take 2 months, so if she can’t get it sooner, they’re going to do a regular angiogram. Also referred for a cardiac MRI and has a holter monitor on. Hoping these tests will
At first I was very biased because I thought maybe I am just overexaggerating a bit. However, the longer I started taking this magnesium supplement, the more I started to realise that this stuff is legit. It has gotten to a point where I don't even experience a severe headache anymore when having a
I had physiotherapy for two years, giving me massages, exercises and dry needling. It sure did improve my health situation, but I noticed that it only had a temporary effect. The therapist then finally suggested me to see a neurologist. Since then I got diagnosed with "out-of-the-sudden" chronic mig
NOTE: Progress updates posted below the main post. I am 59, my wife is 57. We met with Dr. Alan Green in NY on Thurs., and return home next Wednesday (we live in Honolulu) when we will fill our Rapamycin prescriptions (Sirolimus) and begin our program in earnest. Along with Rapamycin, we both curren
(female, 24). 173 cm, 56 kgs, smoker (nicotine). For the past seven years I have been getting what several doctors have diagnosed with “chronic migraines” on a daily basis although the severity changes. A migraine. Every single day. For 7 years. No treatment is working. So you can imagine my desper
BELGIUM (West-Vlaanderen) My wife’s suffering from migraine since 2018. No pain relief found, on the contrary, quantity and intensity raises by day. Since 1st January 2026 she had 3 pain free days in 50 days… average pain index 6-7/10 (not able to function, in bed or zombie). Last 2y she’s working
Is there any clinical reason to use two ARBs together ? (i.e. candesartan 8mg + valsartan 40mg). I can wrap my head around ACEi + ARB combo for extremely resistant and maybe it helps some minority of patients. But this makes no sense to me.
Don't downvote this to oblivion like other comments I've made on this subject in the past. I'm merely curious. I hear all the time that drug prices in the US are really exorbitant in comparison to other parts of the world. So I just wanted to gauge the price between where I am in Australia and the U

Hi, how is it going. Today I'm officially off blood pressure meds completely. With lifestyle changes, low sodium diet, low sugar, aerobic exercise and weight loss. I had blood pressure in the 170 to 180 systolic in January of 2025 after heart surgery on November 2024. I was 230 pounds and am current
I take 100 mg of Losartan daily, but before meds I was easily in the 140-150/90-100 range. Even after taking medication I was usually in the 130/90+ range. My resting heart rate used to sit at about 110 too. I felt like shit and my bod was so tense. But recently I stopped drinking and smoking and be
My blood pressure (seemingly) started giving me problems beginning of this year and I was put on losartan 50mg. I take that once a day and it seems to control my BP well (below 130/80). However, in the 4 months I've been on this medication, I've noticed when I'm on my period, my blood pressure shoot
Just felt compelled to write my positive experience with amlodipine. I've had high blood pressure for about 3-4 years. Average wasn't anything crazy, but around 150-160/90. I was prescribed 50 mg if Losartan, which seemed to do nothing. But I've been in it for the last 2 years. Finally, I decided Lo

25m. I visited the doctor 2 months ago and was diagnosed with high bp and was put on 50mg Losartan. Was usually in the 150s/90 for the first week then it slowly worked but after my monthly visit back my doctor didn’t like the numbers so my dosage was doubled to 100mg. After 1 and a half months of lo

Candesartan is a ARB, while Losartan belongs to the ARB (Angiotensin II Receptor Blocker) class. This means they work through different pharmacological mechanisms, which may influence both efficacy and side effect profiles.
Both medications are approved for Hypertension. When two drugs treat the same condition, the choice between them often depends on the patient's medical history, other medications, tolerability, and prescriber preference.
Losartan carries 1 FDA warning. Patients should discuss all warnings and contraindications with their healthcare provider before starting or switching medications..
