Phenytoin Tips from Pharmacists

• Your doctor will start you on a low dose of phenytoin and increase the dose gradually. Follow the dosing instructions carefully and take the medicine exactly as prescribed.

• Swallow the extended phenytoin sodium capsules whole. Do not cut, crush, or chew them.

• Shake the bottle of phenytoin oral suspension well before use. Use the oral dosing syringe supplied to measure the dose.

• Do not stop taking phenytoin abruptly. This can lead to worsening seizure control. Your doctor will tell you how to lower the dose slowly.

• Phenytoin can cause dizziness and drowsiness. Do not drive or perform other hazardous activities until you know how this medicine affects you.

• Alcohol can make side effects like dizziness worse and affect phenytoin concentrations. Avoid drinking while on this medicine.

• Tell your doctor immediately if you develop any unusual changes in mood or behavior or suicidal thoughts or behavior while on this medication.
