For those who may have actual alergic reactions to Ca channel blockers..... magnesium is a "natural" calcium channel blocker with no side effects (except at very high doses). May be word discussing with your MD.
good luck
Well, it's 3 days later and my rashes and hives are just about 100% gone. So what was thought to be a possible drug interaction with calcium channel blockers was most probably an allergic reaction to dry cleaning chemicals and/or the starch in my shirts.
All is well so far on the vasospasm front as well. Feeling great!
Your advice is very similar to what my GP said yesterday.
Interestingly, I am currently suspecting my dry-cleaning, of all things! The start of my rashes are very coincidently timed with my needing to wear pressed dress shirts/ties at work for presentations. However, the rashes seem to hang on for days once they are established.
I am avoiding any dry-cleaned shirts for a couple of weeks and I am going to see if my skin clears up. I'll report back either way, as it might be of some benefit to other readers/posters who believe that they are reacting to calcium-channel blockers.
If it is contact with dry cleaning chemicals, I'll consider it a blessing, as the Diltiazem I was switched over to seems to be easier to tolerate than the Norvasc I was originally prescribed!
Bill K,
If you have a reaction to a medication, it should not be continued. I would advise you to see an allergist as some of your reaction in your initial story does not seem perfectly consistent with it being from the norvasc.
good luck
