Contents of the pack and other information

1. What Nitrolingual is and what it is used for
Nitrolingual is a sublingual spray which means that you use it
under your tongue. The active ingredient is called glyceryl
trinitrate or GTN for short. GTN is one of a group of medicines
called ‘nitrates’. These relax the muscles around the blood
vessels and make it easier for the heart to do its work.
Nitrolingual helps stop the pain of angina (pain in your chest,
arms or neck especially when you exert yourself). You can
also use the medicine immediately before doing things which
you know will cause you angina pain.

2. What you need to know before you take
Do not take Nitrolingual

if you are allergic (hypersensitive) to nitrates or any
of the other ingredients of Nitrolingual (listed in
Section 6). An allergic reaction may include rash,
itching, difficulty breathing or swelling of the face, lips,
throat or tongue.
if you are very ill because of very low blood
pressure, severe blood loss, acute stroke, bleeding
in the brain, a severe head injury or severe

if you have certain unusual heart conditions (such as
acute circulatory shock (where there is insufficient blood
flow reaching the body’s tissues), this can include
hypovolaemic shock (as a result of low blood volume)
and uncontrolled cardiogenic shock (as a result of
decreased output from the heart), severe mitral stenosis
(a narrowing of the opening to the heart mitral valve) or
obstructive cardiomyopathy (a disease of the heart
muscle causing obstruction of blood flow)), which your
doctor will have told you about.

if you are taking Viagra (sildenafil) or similar products
(e.g., vardenafil, tadalafil) for the treatment of erectile
dysfunction or hypertension of arterial lung vessels. If
you take these products and Nitrolingual, a severe and
possibly dangerous fall in blood pressure can occur. This
would result in collapse, unconsciousness and could be

Other medicines and Nitrolingual

Tell your doctor or pharmacist if you are taking or have
recently taken or might take any other medicines. This is
important as using more than one medicine at the same time
can strengthen or weaken the effect of the medicines. Your
doctor may need to take special care or change the dose. This
is especially important for:

medicines for the treatment of erectile dysfunction or
hypertension of arterial lung vessels (see ‘Do not take

other medicines which can lower blood pressure, such as
beta-blockers, calcium channel blockers and
neuroleptics, vasodilators, anti-hypertensives, diuretics,
tricyclic antidepressants, sapropterin

anti-blood-clotting drugs such as heparin

If you use Nitrolingual very often or if you regularly use other
nitrates, the pain relief you receive may be less. During use
with dihydroergotamine (DHE) (used to treat migraines),
Nitrolingual may lead to an increase in DHE levels, thereby
increasing blood pressure.

Nitrolingual with alcohol

If you drink alcohol before using Nitrolingual, you may feel
dizzy or faint due to low blood pressure.

Pregnancy, breast-feeding and fertility

Tell your doctor if you become pregnant while you are taking
Nitrolingual. You should use Nitrolingual only after discussing
with your doctor the potential benefits to you versus any
potential risks to your unborn child. It is not known whether
glyceryl trinitrate passes into human breast milk. You should
ask your doctor for advice if you are breast-feeding. There is
no sign of a harmful effect with respect to fertility.

Driving and using machines

You should wait at least five minutes after using the spray
before driving or using machinery. If you feel faint, dizzy or
unwell, wait until you feel better. You should be particularly
careful if you have just started using Nitrolingual, if you have
changed your dosage or if you drink alcohol.

Nitrolingual contains ethanol

This medicinal product contains small amounts of ethanol
(alcohol); less than 10mg per metered dose (puff).

3. How to take Nitrolingual

Always take this medicine exactly as described in this leaflet
or as your doctor, pharmacist or nurse has told you. Check
with your doctor, pharmacist or nurse if you are not sure. The
spray is meant for use under your tongue and is not meant to
be inhaled.
The recommended dose is one or two puffs under your
tongue. If symptoms do not resolve, you can repeat this at 5
minute intervals for a maximum of two more times, for a
total of three doses. If, after that, your symptoms have still
not resolved, please seek immediate medical attention. The
spray should work quickly and last about half an hour.

Method of administration

Before you use a new bottle of
Nitrolingual, spray the first puff into
the air to get the pump working
properly. You must also do this if
you have not used the pump for a
week or more. Get used to the feel
of the grooved button in case you
need to use the pump in the dark.
1. Rest or sit quietly, as you may
feel faint or dizzy otherwise,
particularly if you are elderly.
2. Hold the bottle upright with
your finger on the button. You
don’t need to shake the bottle.
3. Open your mouth and put the
bottle next to your chin (see

bottle you can see how much spray you have left. Make sure
that you get a new spray before the old one runs out. Always
keep a spare.
Talk with your doctor about how long you should keep taking

If you take more Nitrolingual than you should

If you take too many puffs you may notice more severe and
pronounced side effects (see section 4), for example, you
may get a bad headache, blurred vision, feel flushed or feel
that your heart is beating more slowly. You may also feel
faint, sweaty, breathless, weak, restless and feel sick or be
sick, or notice a bluish tinge to your lips or a bluish
colouration of the skin. In very rare cases you may develop
methaemoglobinaemia (a disorder of the red blood
cells). If any of these effects persist contact your doctor or
