Antihistamines, Phenothiazine-derivative (Systemic)
Precautions While Using This MedicineTell
the doctor in charge that you are taking this medicine before you have any
skin tests for allergies. The results of the tests may be affected by this
medicine.
When taking phenothiazine-derivative antihistamines on a regular basis,
make sure your doctor knows if you are taking large amounts of aspirin at
the same time (as for arthritis or rheumatism). Effects of too much aspirin,
such as ringing in the ears, may be covered up by the antihistamine.
Phenothiazine-derivative antihistamines 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 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 than
they are normally. Even if taken at bedtime, it may cause some people to feel
drowsy or less alert on arising. Make sure you know how
you react to the phenothiazine-derivative antihistamine you are taking before
you drive, use machines, or do anything else that could be dangerous if you
are not alert
.
Phenothiazine-derivative antihistamines may cause dryness of the mouth,
nose, and throat. For temporary relief of mouth dryness, use sugarless candy
or gum, 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.
This medicine controls nausea and vomiting. For this reason, it may cover
up some of the signs of overdose caused by other medicines or the symptoms
of appendicitis. This will make it difficult for your doctor to diagnose these
conditions. Make sure your doctor knows that you are taking this medicine
if you have other symptoms of appendicitis such as stomach or lower abdominal
pain, cramping, or soreness. Also, if you think you may have taken an overdose
of any medicine, tell your doctor that you are taking this medicine.
