Dilantin (Phenytoin) is a medication used to treat epilepsy, also referred to as an anticonvulsant. It functions by reducing brain impulses that lead to seizures. Dilantin is intended to manage seizures, though it does not treat all seizure types, and your healthcare provider will assess its suitability for you. This medication may also be prescribed for other uses not specified in the medication guide.
If you are prescribed Dilantin to prevent seizures, continue taking it even if you feel well. Discontinuing Dilantin may result in increased seizures. Do not alter your Dilantin dosage without consulting your physician. Inform your doctor if you find that the medication is less effective in managing your condition. Be aware that suicidal thoughts may arise while taking Dilantin; your doctor will need to see you for regular check-ups, so ensure you attend all scheduled appointments. Contact your physician immediately if you experience any new or worsening symptoms, such as mood or behavioral changes, depression, anxiety, or feelings of agitation, hostility, restlessness, hyperactivity (mentally or physically), or thoughts of suicide or self-harm.
Do not take Dilantin if you have a phenytoin allergy. If you have any of the following conditions, you may require a dosage adjustment or special testing: liver disease; porphyria; diabetes; a vitamin D deficiency; or any condition that may weaken bones.
During the first few months of treatment or any time your dosage changes, monitor for any signs of worsening depression or suicidal thoughts. Inform your doctor right away, and ensure your family or caregivers are vigilant for changes in your mood or symptoms. Regular check-ups with your doctor are essential; do not skip any appointments.
Individuals of Asian descent may face a higher risk of developing a rare but serious skin reaction from Dilantin. Your doctor may suggest a blood test before starting the medication to assess the risk of this reaction.
Dilantin can influence your blood sugar levels. If you are diabetic, consistently monitor your blood sugar while taking this medication.
Dilantin is classified as FDA pregnancy category D. Do not use this medication during pregnancy without your doctor’s approval, as it may harm the unborn child. Additionally, Dilantin may be less effective in managing seizures during pregnancy. Use reliable birth control and inform your doctor if you become pregnant while on treatment. Despite the potential risks of Dilantin to the fetus, experiencing a seizure during pregnancy poses risks to both the mother and the baby. Follow your physician’s guidance on the use of Dilantin during pregnancy.
A variety of side effects may occur from phenytoin treatment, including dizziness, drowsiness, blurred vision, difficulty concentrating, an unsteady gait, fatigue, involuntary movements, nausea, vomiting, constipation, stomach pain, and reduced appetite. Long-term use may lead to gum overgrowth in children and young adults, necessitating regular dental care. Maintaining good oral hygiene and gum massage may help mitigate this risk. Rash occurrences can range from 1 in 20 to 1 in 10 individuals, with some cases being severe. Additionally, skin darkening may happen (more frequently in women). Some patients may experience unusual hair growth due to phenytoin, which primarily affects the arms and legs but can also involve the trunk and face; this effect may be permanent.
