After your injection, you will need to stay at the clinic where you receive the injection for at least 3 hours so the doctor can make sure you do not have symptoms of Post-injection Delirium Sedation Syndrome (PDSS). PDSS is a serious problem that can happen if the medicine gets into your blood too fast. Some symptoms of PDSS include drowsiness, dizziness, feeling confused, having trouble talking or walking, seizures, having stiff or shaking muscles, feeling weak, being anxious or angry, passing out or fainting, and having blood pressure changes. When you leave the clinic, someone must be with you. If you have symptoms of PDSS after you leave the clinic or hospital, get medical help right away.
Do not drive or use heavy machinery for the rest of the day after receiving your injection. You may get dizzy or drowsy. Do not stand or sit up quickly, especially 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.
