What safety measures should you take when your child is using phenytoin?
There are some medicines that should not be taken together with phenytoin, or in some cases the dose of phenytoin or the other medicine may need to be adjusted. It is important that you tell your doctor and pharmacist if your child takes any other medications (prescription, over-the-counter, or herbal), including:
Blood levels of phenytoin may be checked routinely. On the day that your child is having a level checked, do not give the next dose until the blood has been drawn.
It is important to keep all appointments with the doctor in order that your child's response to the medication be monitored.
Before your child has any medical tests or procedures (including dental treatment), tell the doctor or dentist in charge that your child is taking phenytoin.
To help prevent problems with your child's gums, practice good dental hygiene. Brush and floss your child's teeth regularly and carefully, and massage the gums. Make sure your child sees a dentist regularly, and tell the dentist that they are taking phenytoin.
Phenytoin may make your child dizzy, drowsy, or less alert than normal, especially at the beginning of therapy. Have your child avoid tasks or activities that require alertness until you see how phenytoin affects them. Tell your child's teacher that they are taking this medication.
Phenytoin may cause your child's urine to turn a pinkish-red or brown colour. This is harmless.
Oral contraceptives (birth control pills) may not work properly if they are taken together with phenytoin. This should be discussed with the doctor.
Keeping a record of your child's seizures, behaviour, and school performance can help to identify the best dose of this medication for your child.
