Why
is Nitro Mack Retard prescribed?
Nitroglycerin
is prescribed to prevent and treat angina pectoris (suffocating
chest pain). This condition occurs when the coronary arteries
become constricted and are not able to carry sufficient oxygen
to the heart muscle. Nitroglycerin is thought to improve oxygen
flow by relaxing the walls of arteries and veins, thus allowing
them to dilate.
Nitroglycerin
is used in different forms. As a patch or ointment, nitroglycerin
may be applied to the skin. The patch and the ointment are for
prevention of chest pain.
Swallowing
nitroglycerin in capsule or tablet form also helps to prevent
chest pain from occurring.
In
the form of sublingual (held under the tongue) or buccal (held
in the cheek) tablets, or in oral spray (sprayed on or under
the tongue), nitroglycerin helps relieve chest pain that has
already occurred. The spray can also prevent anginal pain. The
type of nitroglycerin you use will depend on your condition.

Most
important fact about Nitro Mack Retard
Nitroglycerin
may cause severe low blood pressure (possibly marked by dizziness
or light-headedness), especially if you are in an upright position
or have just gotten up from sitting or lying down. You may also
find your heart rate slowing and your chest pain increasing.
People taking diuretic medication, or who have low systolic
blood pressure (less than 90 mm Hg) should use nitroglycerin
with caution.

How
should you take Nitro Mack Retard?
Since
nitroglycerin is available in many forms, it is crucial for
you to follow your doctor's directions for taking the type of
nitroglycerin prescribed for you. Never interchange brands.
Ideally,
you should take nitroglycerin while sitting down--especially
if you feel dizzy or light-headed--so as to avoid a fall.
--
If you miss a dose...
If
you are using a skin patch or ointment:
Apply
it as soon as you remember. If it is almost time for your regular
dose, skip the one you missed and go back to your regular schedule.
Never apply 2 skin patches at the same time.
If
you are taking oral tablets or capsules:
Take
the forgotten dose as soon as you remember. However, if it is
within 2 hours of your next dose, skip the one you missed and
go back to your regular schedule. Never take 2 doses at the
same time.

Why
should Nitro Mack Retard not be prescribed?
You
should not be using nitroglycerin if you are allergic to it
or to the adhesive in the patch, if you have a head injury,
or if you have any condition caused by increased fluid pressure
in your head. Nitroglycerin should not be taken if you have
severe anemia or if you recently had a heart attack. The capsule
form should not be used if you have closed-angle glaucoma (pressure
in the eye) or suffer from postural hypotension (dizziness upon
standing up). Do not take the tablets if you are using the impotence
drug Viagra.
--------------------------------------------------------------------
Special
warnings about Nitro Mack Retard
If
your vision becomes blurry or your mouth becomes dry while taking
nitroglycerin, it should be discontinued. Contact your doctor
immediately if these symptoms develop.
You
may develop acute headaches if you take nitroglycerin excessively.
Also, some people may develop a tolerance to nitroglycerin,
and it may become less beneficial over time, especially if used
in excess.
Nitroglycerin
tablets lose their effectiveness when exposed to air. If you
are taking sublingual nitroglycerin, you may notice a burning
or tingling sensation. This does not necessarily mean that tablets
which have been exposed to air for a long period of time are
still good.
Take
no more than the smallest possible amount needed to relieve
pain.
Daily
headaches may be an indicator of the drug's activity. Do not
change your dose to avoid the headache, because you may reduce
the drug's effectiveness at the same time.
Before
taking nitroglycerin, tell your doctor if you have had a recent
heart attack, head injury, or stroke; or if you have anemia,
glaucoma (pressure in the eye), or heart, kidney, liver, or
thyroid disease.
If
you use a patch, dispose of it carefully. There is enough drug
left in a used patch to be harmful to children and pets.
Since
nitroglycerin can cause dizziness, you should observe caution
while driving, operating machinery, or performing other tasks
that demand concentration.
The
benefits of applying nitroglycerin to the skin of people experiencing
heart attacks or congestive heart failure have not been established.
If you are using the medication for these conditions, your doctor
will monitor you to prevent low blood pressure and pounding
heartbeat.

Possible
food and drug interactions
If nitroglycerin is taken with certain other drugs, the effects
of either could be increased, decreased, or altered.
Taken
with many high blood pressure drugs, nitroglycerin may cause
extreme low blood pressure (dizziness, fainting, numbness).
Take particular care with calcium channel blockers such as Calan
and Procardia XL, as well as isosorbide dinitrate (Sorbitrate,
Isordil, others), isosorbide mononitrate (Ismo, others), blood
vessel dilators such as Loniten, and beta-blocker medications
such as Tenormin. Nitroglycerin may also cause a severe drop
in blood pressure when taken with the impotence drug Viagra.
Aspirin
can increase the effects of nitroglycerin.
Alcohol
may interact with nitroglycerin and cause a swift decrease in
blood pressure, possibly causing dizziness and fainting.
Also
be alert for an interaction with dihydroergotamine (D.H.E.).
Check with your doctor if you are uncertain about any combination
you plan to take.

Special
information
It has not been determined whether nitroglycerin might harm
a fetus or a pregnant woman. As a result, nitroglycerin should
be used only when the benefits of therapy clearly outweigh the
potential risks to the fetus and woman. It is not known if nitroglycerin
appears in breast milk; therefore, a nursing mother should use
nitroglycerin only on advice of her doctor.
--------------------------------------------------------------------
Recommended
dosage
The
following section is intended to provide guidelines for taking
nitroglycerin. Follow your doctor's instructions carefully for
using nitroglycerin in the form prescribed for you.
ADULTS
--------------------------------------------------------------------
Sublingual or Buccal Tablets
At
the first sign of chest pain, 1 tablet should be dissolved under
the tongue or inside the cheek. You may repeat the dose every
5 minutes until the pain is relieved. If your pain continues
after you have taken 3 tablets in a 15-minute period, notify
your doctor or seek medical attention immediately.
You
may take sublingual or buccal nitroglycerin from 5 to 10 minutes
before starting activities that may cause chest pain.
Patch
Form
A
patch is applied to the skin for 12 to 14 hours. After this
time, the patch is removed; it is not applied again for 10 to
12 hours (a "patch-off" period). Apply the patch as
soon as you remove it from its protective pouch.
Spray
Form
At
the first sign of chest pain, spray 1 or 2 pre-measured doses
onto or under the tongue. You should not use more than 3 doses
within a 15-minute period. If your chest pain continues, you
should contact your doctor or seek medical attention immediately.
The
spray can be used 5 to 10 minutes before activity that might
precipitate an attack.
Ointment
Form
Your
initial dose may be a daily total of 1 inch of ointment. Apply
one-half inch on rising in the morning, and the remaining one-half
inch 6 hours later. If needed, follow your doctor's instructions
for increasing your dosage. Apply in a thin, uniform layer,
regardless of the amount of your dosage. There should be a daily
period where no ointment is applied. Usually, the "ointment-off"
period will last from 10 to 12 hours.
Absorption
varies with site of application--more is absorbed through the
chest.
Sustained-Release
Capsules or Tablets
The
smallest effective amount should be taken 2 or 3 times a day at
8- to 12-hour intervals.

CHILDREN

an overdose, seek medical attention immediately.
