What should I watch for while using this medicine?

Tell your doctor or health care professional if you feel your medicine is no longer working.

Keep this medicine with you at all times. Sit or lie down when you take your medicine to prevent falling if you feel dizzy or faint after using it. Try to remain calm. This will help you to feel better faster. If you feel dizzy, take several deep breaths and lie down with your feet propped up, or bend forward with your head resting between your knees.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this drug affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol can make you more drowsy and dizzy. Avoid alcoholic drinks.

Do not treat yourself for coughs, colds, or pain while you are taking this medicine without asking your doctor or health care professional for advice. Some ingredients may increase your blood pressure.

Where should I keep my medicine?

Keep out of the reach of children.
