Tell your prescriber or health care professional if your symptoms do not improve in 2 or 3 days.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine affects you. Be careful taking other medicines that may also make you tired. This effect may be worse when taking these medicines with products containing carbinoxamine.
