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.

Do not drink hot drinks or alcohol at the same time you take this medicine. Hot drinks and alcohol can increase the flushing caused by this medicine, which can be uncomfortable. Alcohol also can increase possible dizziness. Taking aspirin or an NSAID like ibuprofen 30 minutes before this medicine may help reduce flushing.
