I take Simvastatin 20 mg once a day will this cause shortness of breath?

I take 20mg of simvastatin and have been taking it at that dose for 6 1/2 years. Simvastatin is a cholesterol flowing drug and is taken at lower doses to stabilize coronary artery spasms. It stops your arteries from closing completely. The breathing problem is more likely a pulmonary problem and more likely CHF. I would contact my doctor with these concerns so that the proper test can be run to determine the cause.

They keep telling people that shortness of breath is probably not from Simvastatin but from something else. If that is true then why does it stop when you stop taking the drug? Just from my own experience, statins can cause all kinds of problems and shortness of breath is just one of them.

I'm no expert, but I was prescribed 2 new drugs -- Singulair for allergies and Simvastatin. Like you 20 mg once a day. I experienced shortness of breath -- which I have never had before -- within a few days of starting these meds.

After I stopped taking both, the shortness of breath went away. I think it was the statin which caused the problem.

Its probably not the simvastatin causing it. You should see your dr if you're having a problem like that.
