Potential Side Effects
Cyclosporine can cause mild to severe side effects. They can differ based on how it is administered. Common side effects of the oral and injectable forms include high blood pressure, low magnesium levels, tremors, gum overgrowth, excessive hair growth, and blood clots within the kidneys. Nephrotoxicity, when there are excess toxins within the kidneys, is a common side effect of this medication when it is taken in large doses or over long periods. Less common side effects include liver damage, kidney damage, and lung problems. Although they are not as common, they are more serious.
Vasoconstriction, which is the narrowing of blood vessels, is one side effect that can lead to many of these other damaging effects. As an eyedrop solution, cyclosporine can cause side effects relating to the eyes. Examples include burning, itching, dryness, or redness. Since it is an immunosuppressant, individuals taking this drug may also be at an increased risk of infections, regardless of which form they are taking.
