Like most medications, Dilantin may cause side effects in some people. Some people may have an allergic reaction to Dilantin, causing symptoms like hives, swelling in your face or throat, and difficulty breathing. Dilantin may also cause mood or behavior changes in some people, including depression, anxiety, and increased thoughts of suicide. If you develop a skin rash (scale-like or blister-filled) while taking Dilantin, you should talk to your doctor right away because this may be a sign of a serious complication. Your doctor may switch you to a different treatment or may have you stop taking the medication until the rash is healed. Other serious side effects may include extreme hunger or thirst, changes in urine, slurred speech, tremor or other movement in the eyes and face, and swollen or tender gums. Most of the time, though, side effects are not serious. More common side effects include nausea, vomiting, constipation, dizziness, nervousness, sleep problems, confused, decreased coordination, headache, and joint pain. Talk to your doctor if you're worried about any side effects you're experiencing while taking Dilantin.
