Keveyis side effects
Get emergency medical help if you have signs of an allergic reaction (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).
Keveyis may cause serious side effects. Call your doctor at once if you have:
the first sign of any skin rash, no matter how mild;
an accidental fall;

Accidental falls are more likely in older adults or in people who take high doses of Dichlorphenamide. Use caution to avoid falling or accidental injury while you are taking Keveyis.
