2. VIMPAT may cause you to feel dizzy, have double vision, feel sleepy, or have problems with coordination and walking. Do not drive, operate heavy machinery, or do other dangerous activities until you know how VIMPAT affects you.
3. VIMPAT may cause you to have an irregular heartbeat or may cause you to faint. In rare cases, cardiac arrest has been reported. Call your healthcare provider right away if you:
- have a fast, slow, or pounding heartbeat or feel your heart skip a beat

- have chest pain
- feel lightheaded
- fainted or feel like you are going to faint
If you have fainted or feel like you are going to faint, you should lay down with your legs raised.
4. VIMPAT is a federally controlled substance (CV) because it can be abused or lead to drug dependence. Keep your VIMPAT in a safe place, to protect it from theft. Never give your VIMPAT to anyone else, because it may harm them. Selling or giving away this medicine is against the law.
