This has not been made public yet. However, this is not a hoax, and is legitimately being studied by experts as you read this.
A link was established awhile ago that COVID-19 (the current coronavirus) seems to be especially tough on those with high blood pressure. At first this was dismissed as the simple fact that the virus is tough on anyone with existing medical conditions and older people -- ones more likely to have high blood pressure than the general population.
However, after enough cases were studied, it was found that high blood pressure really was an outlier. Coronavirus really was killing and hospitalizing a disproportionate number of people with high blood pressure, including many who didn't have any serious illness. This has been known for several weeks, however, and is nothing new, albeit not often discussed in the media.
However, the new development involves the "why" of this situation.
There is now a theory that certain common high blood pressure medications are the actual cause of severe illness and death from COVID-19, and not the high blood pressure itself!
This includes any other medication classified as ARBs (angiotensin receptor blockers) or ACE Inhibitors. Other blood pressure medication is still fine to take.
This has not been proven, but is actively being studied as the reason. Many respected members of the medical community have signed off on this being possible, and they are warning friends and family to stop taking ARBs and ACE Inhibitors for the time being.
ACE Inhibitors include:
Accupril (quinapril)
Aceon (perindopril)
Altace (ramipril)
Capoten (captopril)
Lotensin (benazepril)
Mavik (trandolapril)
Monopril (fosinopril)
Prinivil, Zestril (lisinopril)
ARBs include:
azilsartan (Edarbi)
candesartan (Atacand)
eprosartan (Teveten)
irbesartan (Avapro)
telmisartan (Micardis)
valsartan (Diovan)
losartan (Cozaar)
olmesartan (Benicar)
If you have dangerously high blood pressure, you should NOT stop taking these meds. However, if yours is only moderately high -- where it is not likely to kill you in the short term to get off the meds -- then you should stop taking it until more information is known.
For reasons unknown, this information has NOT been made available to the general public yet, perhaps because it hasn't been studied enough. This is a very recent development. In fact, it's so poorly publicized that there's a good chance your doctor or pharmacist is not aware of it yet.
In the next post I will post some copypasta of a medical publication dated 3/11/20 (yesterday) regarding the matter, which currently hides behind a login wall.
