Important
Note
The following information is intended to supplement, not substitute
for, the expertise and judgment of your physician, pharmacist
or other healthcare professional. It should not be construed
to indicate that use of the drug is safe, appropriate, or
effective for you. Consult your healthcare professional before
using this drug.
Uses
This medication contains an antihistamine and decongestant
used to relieve allergy symptoms such as itchy red eyes, stuffy
nose and throat irritation.
How
to Use
Take this medication by mouth on an empty stomach 1 hour before
or two hours after meals as directed, usually twice daily.
Taking this medicine with a high fat meal can decrease its
effectiveness. Do not take antacids containing aluminum and
magnesium within 2 hours of taking this medication. Swallow
the medicine whole. Do not crush or chew the tablet, and do
not take more than prescribed. Do not take this product within
14 days after stopping an MAO Inhibitor (see Drug Interactions).
Side
Effects
Nausea, stomach upset, trouble sleeping, headache, or cold
symptoms may occur. If these persist or worsen, notify your
doctor promptly. Unlikely but report promptly: dizziness,
mental/mood changes, fast heartbeat, fever. Tell your doctor
immediately if any of these highly unlikely but very serious
side effects occur: fainting, irregular heartbeat. Although
drowsiness is very uncommon at usual doses under normal circumstances,
be aware that drowsiness may occur and may effect the ability
to perfom tasks requiring alertness (e.g., driving). If you
notice other effects not listed above, contact your doctor
or pharmacist.
Precautions
Tell your doctor your medical history, including: allergies,
kidney/urinary problems, enlarged prostate, glaucoma (narrow
angle), severe high blood pressure, heart disease, diabetes,
thyroid problems (hyperthyroid). Limit alcohol intake, as
it may aggravate drug side effects. This medication should
be used only when clearly needed during pregnancy. Discuss
the risks and benefits with your doctor. The pseudoephedrine
in this product is excreted into breast milk. Consult your
doctor before breast-feeding. Caution is advised when this
product is used in the elderly since this group may be more
sensitive to side effects.
Drug
Interactions
Tell your doctor of all nonprescription and prescription medication
you may use, especially: MAO inhibitors (e.g., selegiline,
furazolidone, phenelzine, tranylcypromine, moclobemide, procarbazine,
linezolid), certain blood pressure drugs (e.g., methyldopa,
mecamylamine, reserpine, prazosin), digoxin, all adrenaline-like
drugs. Report other drugs which affect the heart rhythm (QTc
prolongation), such as: dofetilide, pimozide, quinidine, sotalol,
procainamide, sparfloxacin, "water pills" (diuretics such
as furosemide or hydrochlorothiazide). Ask your doctor or
pharmacist for more details. Check the labels carefully on
all nonprescription products, such as cough-and-cold medicines
which contain antihistamines and decongestants. Consult your
pharmacist. Do not take this medication for several days before
any allergy testing since test results can be affected. Do
not start or stop any medicine without doctor or pharmacist
approval.
Overdose
If overdose is suspected, contact your local poison control
center or emergency room immediately. Symptoms of overdose
may include irregular or unusually slow or fast heartbeat,
unusual nervousness or excitement, rapid breathing, confusion,
hallucinations, and seizures.
