IMPORTANT INFORMATION FOR YOU.
-
Keep this leaflet. You may need to read it again.
-
If you have any further questions, ask your doctor, pharmacist or
nurse.

This medicine has been prescribed for you only. Do not pass it on to

If you get any side effects, talk to your doctor, pharmacist or nurse.
This includes any
possible side effects not listed in this leaflet. See section 4
• Thyroxine is a hormone produced by the thyroid gland.
Levothyroxine is used to replace
thyroxine in people whose thyroid gland does not work properly. You
will usually need to
take this medicine for the rest of your life and must not stop taking
it, or change the dose,
without speaking to your doctor first.
• This medicine can affect the way other medicines work (See Section
2 ‘Taking other
medicines’). If you take medicines to control diabetes or warfarin
to prevent blood clots, the dose
may need to be adjusted by your doctor when you start taking Eltroxin
tablets.
• You will start off taking a low dose of this medicine (See Section
3 ‘How to take’). Your
doctor will then increase the dose gradually at 3 – 4 week intervals
until your thyroxine levels
are corrected. This will help to reduce the chance of side effects.
• You will need regular blood tests whilst you are taking this
medicine.
• These tablets can be taken by both adults and children. If you are
giving this medicine to your
child make sure you know how many and when to give the tablets (See
Section 3 ‘How to take’)
and what side effects to look out for (See Section 4 ‘Possible side
effects’).

4 CLINICAL PARTICULARS
4.1 THERAPEUTIC INDICATIONS
Recommended clinical indications: Control of hypothyroidism,
congenital hypothyroidism in infants, acquired hypothyroidism
in children and juvenile myxoedema.
4.2 POSOLOGY AND METHOD OF ADMINISTRATION
Posology
A pre-therapy ECG is valuable because ECG changes due to
hypothyroidism may be confused with ECG evidence of cardiac
ischemia.
If too rapid an increase in metabolism is produced (causing diarrhoea,
nervousness, rapid pulse, insomnia, tremors, and
sometimes anginal pain where there is latent cardiac ischemia) dosage
must be reduced, or withheld, for a day or two, and
then re-started at a lower dose level.
Initial monitoring and dose adjustments.
It is especially necessary when starting Eltroxin to establish a
maintenance dose. The timing of this blood test depends on
patients symptoms. If their symptoms have improved after starting
Eltroxin, patients should have their TSH level measured at
around 6 weeks after starting Eltroxin. If a patient still has
symptoms 2-3 weeks after starting Eltroxin, they will need a TSH level
taken earlier.
_Adults (under 50 years age):_
Initially 50 to 100 micrograms daily (2 to 4 tablets daily),
preferably taken before breakfast or the first meal of the day. Adjust
at
three to four week intervals by 50 micrograms until normal metabolism
is steadily maintained. The final daily dose may be up
to 100 to 200 micrograms. In younger patients
