Side Effects
Mild redness/irritation of the skin under the patch may occur. This will usually improve even if the patch is left on. If this effect persists or worsens, notify your doctor or pharmacist promptly. If swelling, severe irritation, or red bumps appear on the skin around or under the patch, contact your doctor immediately. Headache, stomach pain, loss of appetite, trouble sleeping, dizziness, nausea, vomiting, lightheadedness, irritability, nervousness, stuffy nose, dry mouth, constipation, or (rarely) drowsiness may also occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects.
