Consumer Medicine Information

What is in this leaflet

This leaflet answers some of the common questions about Invega. It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.

If you have any concerns about using Invega, ask your doctor or pharmacist. Your doctor and pharmacist have more information.

Keep this leaflet with your medicine. You may need to read it again.

What Invega is used for

Invega belongs to a group of medicines called antipsychotic agents which improve the symptoms of certain types of mental illness.

It is used to treat symptoms of schizophrenia, a mental illness with disturbances in thinking, feelings and behaviour. It is also used to treat other types of related psychoses. Invega helps to correct a chemical imbalance in the brain associated with these conditions.

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.

Your doctor, however, may prescribe this medicine for another use.

Ask your doctor if you have any questions about why it has been prescribed to you.

Invega is not addictive.

  1. Older People
    Your doctor may adjust your dose based on your kidney function.

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.

How to take it

Your doctor will decide the Invega strength and dose most suitable for you.

Invega should be taken 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.

The tablet should be swallowed whole with water or other liquid. Invega tablets must not be chewed, split or crushed.

Your doctor will decide the 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 your doctor's instructions carefully and do not change or stop your dosage without consulting your doctor first.

Invega is not recommended for children under 18 years.

If you forget to take it

  • If you forget to take it, take the missed dose as soon as you remember. Then resume taking Invega as you normally would the following morning.
  • Do not take a double dose to make up for the one 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.

While you are using it

Things you must 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.

Tell your doctor if you are pregnant or planning to become pregnant.

Tell your doctor immediately if you 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.

If any doctors, dentists or pharmacists want to start you on any new medicines listed under point 3 of 'Before you start to take it' (above), tell them you are taking Invega. Your doctor, dentist or pharmacist will need to consider whether any new medicines will affect your Invega.

Things you must not do

Do not use Invega to treat any other complaint unless your doctor says so.

Do not give this medicine to anyone else, even if their symptoms seem similar.

Do not change your dose or stop taking Invega without first checking with your doctor.

Do not drink alcohol. Invega can increase the effects of alcohol.

Things to be careful of

Ask your doctor before taking any other medicines.

Invega can increase the effects of medicines which slow your reactions. Always ask your doctor or pharmacist before taking other medicines including herbal treatments and medicines that can be bought in a pharmacy or supermarket.

Avoid driving or operating machinery until you are sure that Invega does not affect your alertness. 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.

Avoid excessive eating. 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.
