There are reasons why ramipril (an ARB) should have a lower cough incidence than ACE inhibitors, but people react differently to medication.
Mistyped there ? ( ramipril is an ACEI, not an ARB. Losartan’s the ARB )
ACEIs are tolerated just fine by many many people as are lots of the alternatives; nothing suits everybody. Pretty much everything folk have reported up there is well-known to happen in SOME patients
Those who get coughs are describing a legit adverse effect that prompts a change of drug class for most of them
The itch etc, also legit but rarer (though probably the same underlying mechanism)
The mood, tiredness etc also reasonably common (me? – no idea how that comes about)
Dizziness is MOSTLY when first starting (everybody gets low dose to start) or on dose increases. Majority don’t get it continuously
Fitting – !! (I wonder what your sodium level and/or BP were at the time)
As said, give it a go & see. Chances are you’ll be one of those who gets on just fine with it
