6) Further information

1) What Serc is and what it is used for
Serc contains betahistine. This medicine is called a histamine analogue. It
is used to treat:
• dizziness (vertigo)
• ringing in the ears (tinnitus)
• hearing loss suffered by people with Ménière's disease
This medicine works by improving blood flow in the inner ear. This lowers
the build up of pressure.

2) Before you take Serc
Do not take Serc If:
• You are allergic to any of the ingredients in the tablets (see section 6
for further details).
• You have high blood pressure due to an adrenal tumour
(phaeochromocytoma).
If any of the above applies to you, do not take this medicine and talk to
your doctor.
Take special care and tell your doctor if:
• you have a stomach ulcer
• you have asthma
• you are pregnant or planning to become pregnant
• you are breast-feeding
If any of the above applies to you, talk to your doctor before taking this
medicine.

In particular, tell your doctor or pharmacist if you are taking any of the
following medicines:
• Anti-histamines – these may (in theory) lower the effect of Serc. Also,
Serc may lower the effect of anti-histamines.
• Monoamine-oxidase inhibitors (MAOIs) – used to treat depression or
Parkinson’s disease. These may increase the exposure of Serc.
Taking Serc with food and drink
You can take Serc with or without food.
Pregnancy and breast-feeding
Do not take Serc if you are pregnant unless your doctor has decided that it
is absolutely necessary. Ask your doctor for advice.
Do not breast-feed while using Serc unless instructed by your doctor. It is
not known if Serc passes into breast milk.
Driving and using machines
Serc is not likely to affect your ability to drive or use tools or machinery.
However, remember that diseases for which you are being treated with
Serc (vertigo, tinnitus and hearing loss associated with Ménière’s
syndrome) can make you feel dizzy or be sick, and can affect your ability
to drive or use machines.

3) How to take Serc
How to take Serc
• Swallow the tablets with water.
• Preferably take the tablet with a meal.
How much Serc to take

your dose.

How to stop taking Serc
Keep taking your tablets until your doctor tells you to stop.
Even when you start feeling better, your doctor may want you to carry on
taking the tablets for some time to make sure that the medicine has
worked completely.






Keep all medicines out of the sight and reach of children.

tell you what to do.

waste. Ask your pharmacist how to dispose of medicines no longer
required. These measures will help to protect the environment.

If you take more Serc than you should
If you or someone else takes too much Serc (an overdose), talk to a doctor
or go to a hospital straight away. Take the medicine pack with you.



If you forget to take Serc
If you miss a tablet, wait until the next dose is due. Do not try to make up
for the dose you have missed.
