Karbinal Er

Drowsiness, dizziness, headache, constipation, stomach upset, blurred vision, decreased coordination, or dry mouth/nose/throat may occur. These effects may decrease as your body adjusts to the medication. If any of these effects last or get worse, contact your doctor or pharmacist promptly.

To relieve dry mouth, suck on (sugarless) hard candy or ice chips, chew (sugarless) gum, drink water, or use a saliva substitute. Carbinoxamine can dry up and thicken mucus in your lungs, making it more difficult to breathe and clear your lungs. To help prevent this effect, drink plenty of fluids unless otherwise directed by your doctor.

To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
