What should I watch for?
The first time you take this medicine or have an increase in dose make sure there is a responsible person nearby. You may experience mood changes, easy laughter, or other changes in behavior.
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. Do not stand or sit up quickly, especially if you have low blood pressure or if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol may interfere with the effect of this medicine. Avoid alcoholic drinks.
If you are taking this medicine to improve your appetite, this is only part of your therapy. Discuss what you can eat and ways of improving your diet with your health care professional or nutritionist. Frequent small snacks as well as regular meals can help provide extra calories and protein.
Do not smoke marijuana while you are taking this medicine. It is similar to one of the active substances found in marijuana. You are at increased risk of serious heart and/or nervous system side effects if these drugs are used together.
