4. How do I use INVEGA?
How much to use
Your doctor will decide the strength and dose of INVEGA that is suitable for you,
based on your condition and kidney function.
The usual dosage for INVEGA is between 3 mg and 12 mg once daily.
For people with severe kidney problems the starting dose may be as low as 3 mg every
other day. Your doctor may later decide to increase the dose as required for best
symptoms control.
Follow the instructions provided and use INVEGA until your doctor tells you to stop.
When to use INVEGA
INVEGA should be used once daily, in the morning, at about the same time each day.
You should decide whether you will always take INVEGA on an empty stomach before breakfast,
or always with food at breakfast. You must not switch between taking INVEGA on an
empty stomach and taking it with food.
How to use INVEGA
The tablet should be swallowed whole with water or other liquid. INVEGA tablets must
not be chewed, split or crushed.
INVEGA tablets are formulated with a special shell that controls the release of the
active ingredient gradually throughout the day. The tablet shell does not dissolve
completely after all the drug has been released and sometimes the tablet shell may
be seen in your stool. This is normal.
If you forget to use INVEGA
INVEGA should be used regularly at the same time each day. If you miss your dose at
the usual time, take the missed dose as soon as you remember. Then resume taking INVEGA
as you normally would the following morning.
If it is almost time for your next dose, skip the dose you missed and take your next
dose when you are meant to.
Do not take a double dose to make up for the dose you missed.
If you forget to take it for a number of days or more, tell your doctor before starting
your medicine again.
If you have problems remembering when to take your medicine, ask your pharmacist for
some hints.
If you use too much INVEGA

phone the Poisons Information Centre

contact your doctor, or
go to the Emergency Department at your nearest hospital.

nausea, excessive muscle stiffness, increased heart rate, shortness of breath, very
low blood pressure causing fainting or unconsciousness.

5. What should I know while using INVEGA?
Things you should do
Follow your doctor's instructions carefully.
Always seek your doctor's advice before changing or stopping treatment. Your doctor
will be happy to discuss any questions you may have with your treatment.
Ask your doctor or pharmacist before taking any other medicines.

and medicines that can be bought in a pharmacy or supermarket.
Call your doctor straight away if you:
are pregnant or planning to become pregnant.
notice any involuntary movements of the tongue, mouth, cheeks or jaw.
These may be symptoms of a condition called tardive dyskinesia, which can develop
in people taking antipsychotic medicines, including INVEGA. This condition is more
likely to occur during longer term treatment and in older women. In very rare cases,
these symptoms may be permanent. However, if detected early, these symptoms are usually
reversible.
Remind any doctor, dentist or pharmacist you visit that you are using INVEGA.
Your doctor, dentist or pharmacist will need to consider whether any new medicines
will affect your INVEGA.
Things you should not do

do so.

There is a possibility of weight gain when taking INVEGA. Your doctor may monitor
your body weight or recommend strategies to assist with weight management.
Taking it for the first time
At the start of treatment, you may have a fall in blood pressure making you feel dizzy
on standing up, or your heart may beat faster. These should go away after a few days.
Tell your doctor if these symptoms continue or worry you.
Driving or using machines
Be careful before you drive or use any machines or tools until you know how INVEGA
affects you.
INVEGA may cause dizziness, drowsiness or light-headedness in some people, especially
after the first dose. Make sure you know how you react to INVEGA before you drive
a car, operate machinery, or do anything else that could be dangerous if you are dizzy.
