1. What Securon SR is and what is it
used for
Securon SR tablets belong to a group of medicines
called calcium channel blockers. Calcium channel
blockers change the amount of calcium getting into
the muscle cells in your heart and blood vessels.
This can change the strength and speed with which
your heart beats. It also opens up the blood vessels
so blood can be pumped around the body more
easily. This helps more oxygen to get to your heart
muscle and can lower your blood pressure.
Securon SR tablets are used to treat hypertension
(high blood pressure) and to prevent angina (chest
pain) attacks. The tablets may also be prescribed
following a heart attack, to prevent another attack
occurring.
The active ingredient in Securon SR tablets is
verapamil hydrochloride.

2. What you need to know before you
take Securon SR

• Do you have a condition where the nerve to
muscle transmission is affected e.g. myasthemia
gravis, Lambert-Eaton syndrome, advanced
Duchenne muscular dystrophy?
• Are you being treated with ivabradine (for heart
conditions)?

types of infection

requires you to be alert, until you know how the
tablets affect you.
Securon SR can make some people feel dizzy,
especially when they first start to take the tablets.
Other important information
Do NOT drink grapefruit juice whilst taking your
tablets as it can affect the absorption of this
medicine. This does not occur with other fruit juices
such as orange, apple or tomato juice.
Drinking alcohol
Securon SR will increase the time your body takes to
get rid of alcohol. This means that you may not have
to drink as much for your blood alcohol levels to be
above the legal limit to drive. It will also take you
longer to sober up.
Pregnancy and breast feeding
Please discuss with your doctor if you are pregnant,
planning to become pregnant or are breast feeding.

3. How to take Securon SR
ALWAYS take this medicine exactly as your doctor
has told you. Check with your doctor if you are not
sure.
TAKE YOUR TABLETS with a glass of water. You
should swallow the tablets without chewing or
crushing them. It does not matter if you have not
eaten.
The number of tablets that you will need to take will
depend on what you are being treated for:

ADULTS:
Hypertension (high blood pressure)
The recommended dose is one Securon SR 240 mg
tablet a day. If you have not taken Securon SR 240
mg before, your doctor may prescribe a lower dose
such as a Half Securon SR 120 mg tablet each day.
The maximum dose to treat high blood pressure is
480 mg each day. This is usually taken as one
Securon SR 240 mg tablet in the morning and one in
the evening, leaving a gap of about 12 hours
between each dose.
Angina (chest pain)
The usual starting dose for angina is one Securon
SR 240 mg tablet taken twice a day. You should take
one tablet in the morning and one in the evening,
with a gap of about 12 hours in between them. Your
doctor may prescribe a lower dose according to your
symptoms.

each day. This may be taken as one Securon SR
240 mg tablet in the morning and a Half Securon SR
120 mg tablet in the evening or as one Half Securon

doctor will usually wait at least a week after your

as you remember, unless it is almost time for your
next dose. If it is, do not take the missed dose at all.
Do not take double dose to make up for a forgotten
tablet.

If you stop taking Securon SR
If you stop taking your tablets your condition may get
worse. It is important that you keep taking these

if your doctor advises you to do so (e.g. if a lower
