This medicine will add to the effects of alcohol and other CNS depressants
(medicines that slow down the nervous system, possibly causing drowsiness).
Some examples of CNS depressants are antihistamines or medicine for hay fever,
other allergies, or colds; sedatives, tranquilizers, or sleeping medicine;
prescription pain medicine or narcotics; barbiturates; medicine for seizures;
muscle relaxants; or anesthetics, including some dental anesthetics. Check with your doctor before taking any of the above while
you are using this medicine
.
This medicine may cause some people to become drowsy or less alert or to
have blurred vision or muscle stiffness, especially as the amount of medicine
is increased. Even if you take pimozide at bedtime, you may feel drowsy or
less alert on arising. Make sure you know how you react
to this medicine before you drive, use machines, or do anything else that
could be dangerous if you are not alert or able to see well or if you do not
have good muscle control
.
Although not a problem for many patients, dizziness, lightheadedness, or
fainting may occur when you get up from a sitting or lying position. Getting
up slowly may help. If the problem continues or gets worse, check with your
doctor.
Before having any kind of surgery, dental treatment,
or emergency treatment, tell the medical doctor or dentist in charge that
you are using this medicine
. Taking pimozide together with medicines
that are used during surgery or dental or emergency treatment may increase
the CNS depressant effects.
Pimozide may cause dryness of the mouth. For temporary relief, use sugarless
gum or candy, melt bits of ice in your mouth, or use a saliva substitute.
However, if your mouth continues to feel dry for more than 2 weeks, check
with your medical doctor or dentist. Continuing dryness of the mouth may increase
the chance of dental disease, including tooth decay, gum disease, and fungus
infections.
