Frequent question: Does Tylenol dilate or constrict blood vessels?

Acetaminophen is a pain reliever and a fever reducer. Caffeine is a stimulant that causes narrowing of blood vessels (vasoconstriction). Isometheptene also causes narrowing of blood vessels.

What medications dilate blood vessels?

Some drugs used to treat hypertension, such as calcium channel blockers also dilate blood vessels. But the vasodilators that work directly on the vessel walls are hydralazine and minoxidil.

Do painkillers dilate blood vessels?

Dilated blood vessels (vasodilation): Some people who take opioids experience vasodilation, the widening of the blood vessels. Vasodilation can cause low blood pressure. Severely low blood pressure can deprive your heart and brain of the oxygen they need to function.

Does Tylenol affect blood pressure?

Acetaminophen, the active ingredient in Tylenol and other drugs, has been shown in some studies to cause a mild increase in blood pressure, but it hasn’t been associated with stroke or heart attack. Still, this medication has its own side effects and poses a risk of liver damage when taken in overly large doses.
