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

Keep this leaflet with this medicine. You may need to read it again.
What Fluoxetine RBX is used for
Fluoxetine RBX is used to treat:
- obsessive compulsive disorder (OCD)
- premenstrual dysphoric disorder (PMDD)
Ask your doctor if you have any questions about why Fluoxetine RBX has been prescribed for you.
Your doctor may have prescribed Fluoxetine RBX for another reason.
Fluoxetine belongs to a group of medicines called selective serotonin reuptake inhibitors (SSRIs). SSRIs are thought to work by their action on brain chemicals called amines which are involved in controlling mood. Fluoxetine RBX is available only with a doctor's prescription.
Fluoxetine RBX is not recommended for use in children and adolescents under 18 years of age.
Before you take Fluoxetine RBX
When you must not take it
Do not take Fluoxetine RBX if you are allergic to
- any medicines containing fluoxetine
- any of the ingredients listed at the end of this leaflet.
Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.
Do not take Fluoxetine RBX if you are taking another medicine for depression called a monoamine oxidase inhibitor (MAOI) or have been taking a MAOI within the last 14 days. Check with your doctor or pharmacist if you are unsure as to whether or not you are taking a MAOI
If you do take Fluoxetine RBX while you are taking a MAOI, you may experience shaking (tremor), shivering, muscle stiffness, fever, rapid pulse, rapid breathing or confusion.
Do not take Fluoxetine RBX if you are taking another medicine called pimozide to treat disturbances in thinking, feelings and behaviour. Taking pimozide together with Fluoxetine RBX may alter the rhythm of your heart.
Do not take Fluoxetine RBX if the packaging is torn or shows signs of tampering or the capsules or tablets do not look quite right.
Do not take Fluoxetine RBX if the expiry date on the pack has passed. If it has expired or is damaged, return it to your pharmacist for disposal.
If you are not sure whether you should start taking Fluoxetine RBX, talk to your doctor.
Before you start to take it
Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.
Tell your doctor if you are pregnant or plan to become pregnant. Your doctor will discuss the risks and benefits of taking Fluoxetine RBX during pregnancy. If Fluoxetine RBX is taken during pregnancy, you should be careful, particularly at the end of pregnancy. Transitory withdrawal symptoms have been reported rarely in the newborn after maternal use in the last 3 months of pregnancy.
Tell your doctor if you are breastfeeding or wish to breastfeed
Tell your doctor if you have, or have had, any medical conditions, especially the following:
- liver problems

- a bleeding disorder or a tendency to bleed more than usual.
Tell your doctor if you drink alcohol. Although drinking alcohol is unlikely to affect your response to Fluoxetine RBX, your doctor may suggest avoiding alcohol while you are being treated for depression.
There is no specific information available to recommend the use of Fluoxetine RBX in children and adolescents under 18 years of age.
If you have not told your doctor about any of the above, tell them before you start taking Fluoxetine RBX.

How to take Fluoxetine RBX
Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.
How much to take
Your doctor will tell you how much Fluoxetine RBX you need to take each day. The usual dose for Fluoxetine RBX is one capsule taken once a day. Your doctor may increase or decrease your dose depending on your condition.
For premenstrual dysphoric disorder (PMDD), Fluoxetine RBX may be prescribed to be taken every day or only during a certain part of the month. Your doctor will prescribe the dosing schedule that is right for you.
How to take it
Swallow the capsules whole with a glass of water.
When to take it
Fluoxetine RBX is usually taken as a single morning dose.
If your doctor tells you to take Fluoxetine RBX twice a day, take a dose in the morning and at noon.
Take your medicine at about the same time each day.
Taking it at the same time each day will help you remember when to take it.
It does not matter if you take this medicine before or after food.
How long to take it
Continue taking Fluoxetine RBX for as long as your doctor recommends.
The length of treatment with Fluoxetine RBX will depend on how quickly your symptoms improve.
Most medicines of this type take time to work so don't be discouraged if you do not feel better right away. While some symptoms will be relieved sooner than others, Fluoxetine RBX commonly takes two to four weeks before improvement is really apparent.
If you do not start to feel better in about four weeks, check with your doctor.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose that you missed.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (13 11 26) for advice or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Fluoxetine RBX. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you have taken too much Fluoxetine RBX, you may feel sick in the stomach, vomit, feel restless, agitated or excited.
