It is important not to let side effects keep you from taking your medication, unless you experience any of the following, in which case you should call your doctor:

• Sores, blisters, or ulcers in your mouth
• Blisters on the skin
• Excessive bleeding or bleeding won't stop
• Stomach pain and tenderness
• Fever
• Unusual infections
• Other unusual symptoms while taking a seizure medicine

Your doctor may ask you about side effects; it’s important to let them know how you are feeling.

Here are some suggestions for things to keep track of:

• What the side effect felt like
• How much the side effect bothers you (did it stop you from doing daily activities or taking the medication?)
• If you could put up with this side effect if it meant you could reduce the number of seizures you have
• How much of the medication you took
• Timing (what time of day did it start, how long it lasted, and if it went away)
