PACKAGE LEAFLET: INFORMATION FOR THE USER PROZAC® LIQUID FLUOXETINE LIQUID 20mg/5ml (fluoxetine hydrochloride)
Your medicine is known as Prozac Liquid or Fluoxetine Liquid 20mg/5ml; it will be referred to as Prozac or Prozac Oral Liquid throughout this leaflet.
EIGHT IMPORTANT THINGS YOU NEED TO KNOW ABOUT PROZAC
Prozac treats depression and anxiety disorders.
Like all medicines it can have unwanted effects. It is therefore important that you and your doctor weigh up the benefits of treatment against the possible unwanted effects, before starting treatment.
Prozac is not for use In children and adolescents under 18. See
section 2, Children and adolescents aged 8 to 18 years.
Prozac won’t work straight away. Some people taking antidepressants feel worse before feeling better. Your doctor should ask to see you again a couple of weeks after you first start treatment. Tell your doctor if you haven't started feeling better. See section 3, How to take Prozac oral solution.
Some people who are depressed or anxious think of harming or killing themselves. If you start to feel worse, or think of harming or killing yourself, see your doctor or go to a hospital straight away. See section 2.
Don’t stop taking Prozac without talking to your doctor. If you
stop taking Prozac suddenly or miss a dose, you may get withdrawal effects. See section 3 for further information.
If you feel restless and feel like you can’t sit or stand still, tell your doctor. Increasing the dose of Prozac may make these feelings worse. See section 4, Possible side-effects.
Taking some other medicines with Prozac can cause problems.
You may need to talk to your doctor. See section 2, Taking other medicines.
If you are pregnant or planning to get pregnant, talk to your doctor. See section 2, Pregnancy, breast-feeding and fertility.
Read all of this leaflet carefully before you start taking this medicine because it contains important information for you.
- Keep this leaflet. You may need to read it again.
- If you have any further questions, ask your doctor or pharmacist.
- This medicine has been prescribed for you only. Do not pass it on to others. It may harm them, even if their signs of illness are the same as yours.

6. Content of the pack and other information
1. What is Prozac oral solution and what it is used for
Prozac 20 mg per 5 ml contains the active substance fluoxetine which is one of a group of medicines called selective serotonin reuptake inhibitors (SSRI) antidepressants.
This medicine is used to treat the following conditions:
Adults:
• Major depressive episodes
• Obsessive-compulsive disorder
• Bulimia nervosa: Prozac is used alongside psychotherapy for the reduction of binge-eating and purging.
Children and adolescents aged 8 years and above:
• Moderate to severe major depressive disorder, if the depression does not respond to psychological therapy after 4-6 sessions. Prozac should be offered to a child or young person with moderate to severe major depressive disorder only in combination with psychological therapy.
How Prozac works
Everyone has a substance called serotonin in their brain. People who are depressed or have obsessive-compulsive disorder or bulimia nervosa have lower levels of serotonin than others. It is not fully understood how Prozac and other SSRIs work but they may help by increasing the level of serotonin in the brain.
Treating these conditions is important to help you get better. If it's not treated, your condition may not go away and may become more serious and more difficult to treat.
You may need to be treated for a few weeks or months to ensure that you are free from symptoms.
2. What you need to know before you take Prozac
Do not take Prozac if you are:
• allergic to fluoxetine or any of the other ingredients of this medicine (listed in section 6). If you develop a rash or other allergic reactions (like itching, swollen lips or face or shortness of breath), stop taking the oral solution straight away and contact your doctor immediately.
• taking other medicines known as irreversible, non-selective monoamine oxidase inhibitors (MAOIs), since serious or even fatal reactions can occur (e.g. iproniazid used to treat depression).
Treatment with Prozac should only be started at least 2 weeks after discontinuation of an irreversible, non-selective MAOI.
Do not take any irreversible, non-selective MAOIs for at least 5 weeks after you stop taking Prozac. If Prozac has been prescribed for a long period and/or at a high dose, a longer interval needs to be considered by your doctor.
• taking metoprolol (to treat heart failure) because there is an increased risk of your heart beat becoming too slow.
Warnings and precautions
Talk to your doctor or pharmacist before taking Prozac if any of the following applies to you:
• heart problems;
• appearance of fever, muscle stiffness or tremor, changes in your mental state like confusion, irritability and extreme agitation; you may suffer from the so-called “serotonin syndrome” or “neuroleptic malignant syndrome”. Although this syndrome occurs rarely it may result in potentially life threatening conditions; contact your doctor immediately, since Prozac might need to be discontinued.
• mania now or in the past; if you have a manic episode, contact your doctor immediately because Prozac might need to be discontinued;
• history of bleeding disorders or appearance of bruises or unusual bleeding;
• ongoing treatment with medicines that thin the blood (see ‘Other medicines and Prozac)
• epilepsy or fits. If you have a fit (seizures) or experience an increase in seizure frequency, contact your doctor immediately; Prozac might need to be discontinued;
• ongoing ECT (electro-convulsive therapy);
• ongoing treatment with tamoxifen (used to treat breast cancer) (see ‘Other medicines and Prozac’);
• starting to feel restless and cannot sit or stand still (akathisia). Increasing your dose of Prozac may make this worse;
• diabetes (your doctor may need to adjust your dose of insulin or other antidiabetic treatment);
• liver problems (your doctor may need to adjust your dosage);
• low resting heart-rate and/or if you know that you may have salt depletion as a result of prolonged severe diarrhoea and vomiting (being sick) or usage of diuretics (water tablets);
• ongoing treatment with diuretics (water tablets), especially if you are elderly;
• glaucoma (increased pressure in the eye).
Thoughts of suicide and worsening of your depression or anxiety disorder.
If you are depressed and/or have anxiety disorders you can sometimes have thoughts of harming or killing yourself. These may be increased when first starting antidepressants, since these
medicines all take time to work, usually about two weeks but sometimes longer.
You may be more likely to think like this:
If you have previously had thoughts about killing or harming yourself.
If you are a young adult. Information from clinical trials has shown an increased risk of suicidal behaviour in adults aged less than 25 years with psychiatric conditions who were treated with an antidepressant.
If you have thoughts of harming or killing yourself at any time, contact your doctor or go to a hospital straight away.
You may find it helpful to tell a relative or close friend that you are depressed or have an anxiety disorder, and ask them to read this leaflet. You might ask them to tell you if they think your depression or anxiety is getting worse, or if they are worried about changes in your behaviour.
Children and adolescents aged 8 to 18 years:
Patients under 18 have an increased risk of side-effects such as suicide attempt, suicidal thoughts and hostility (predominantly aggression, oppositional behaviour and anger) when they take this class of medicines. Prozac should only be used in children and adolescents aged 8 to 18 years for the treatment of moderate to severe major depressive episodes (in combination with psychological therapy) and it should not be used to treat other conditions.
Additionally, only limited information concerning the long-term safety of Prozac on growth, puberty, mental, emotional and behavioural development in this age group is available. Despite this, and if you are a patient under 18, your doctor may prescribe Prozac for moderate to severe major depressive episodes, in combination with psychological therapy, because he/she decides that this is in your best interests. If your doctor has prescribed Prozac for a patient under 18 and you want to discuss this, please go back to your doctor. You should inform your doctor if any of the symptoms listed above develop or worsen when patients under 18 are taking Prozac.
Prozac should not be used in the treatment of children under the age of 8 years.
Other medicines and Prozac
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Do not take Prozac with:
• Certain irreversible, non-selective monoamine oxidase inhibitors (MAOIs), some used to treat depression.
Irreversible, non-selective MAOIs must not be used with Prozac as serious or even fatal reactions (serotonin syndrome) can occur (see section “Do not take Prozac”). Treatment with Prozac should only be started at least 2 weeks after discontinuation of an irreversible, non-selective MAOI (for instance tranylcypromine). Do not take any irreversible, non-selective MAOIs for at least 5 weeks after you stop taking Prozac. If Prozac has been prescribed for a long period and/or at a high dose, a longer interval than 5 weeks may need to be considered by your doctor.
• metoprolol when used for heart failure; there is an increased risk of your heart beat becoming too slow.
Prozac may affect the way the following medicines work (interaction):
• tamoxifen (used to treat breast cancer); because Prozac may change the blood levels of this drug, resulting in the possibility of a reduction in the effect of tamoxifen, your doctor may need to consider prescribing a different antidepressant treatment.
• monoamine oxidase inhibitors A (MAOI-A) including moclobemide, linezolid (an antibiotic) and methylthioninium chloride (also called methylene blue, used for the treatment of medicinal or chemical product induced methemoglobinemia): due to the risk of serious or even fatal reactions (called serotonin syndrome). Treatment with fluoxetine can be started the day after stopping treatment with reversible MAOIs but the doctor may wish to monitor you carefully and use a lower dose of the MAOI-A drug.
• mequitazine (for allergies); because taking this drug with Prozac may increase the risk of changes in the electrical activity of the heart.
• phenytoin (for epilepsy); because Prozac may influence the blood levels of this drug, your doctor may need to introduce phenytoin more carefully and carry out check-ups when given with Prozac.
• lithium, selegiline, St. John’s Wort, tramadol (a painkiller), triptans (for migraine) and tryptophan; there is an increased risk of mild serotonin syndrome when these drugs are taken with Prozac. Your doctor will carry out more frequent checkups.
• medicines that may affect the heart’s rhythm, e.g. Class IA and III antiarrhythmics, antipsychotics (e.g. phenothiazine derivatives, pimozide, haloperidol), tricyclic antidepressants, certain antimicrobial agents (e.g. sparfloxacin, moxifloxacin, erythromycin IV, pentamidine), anti-malaria treatment particularly halofantrine or certain antihistamines (astemizole, mizolastine), because taking one or more of these drugs with Prozac may increase the risk of changes in the electrical activity of the heart.
• Anti-coagulants (such as warfarin), NSAID (such as ibruprofen, diclofenac), aspirin and other medicines which can thin the blood (including clozapine, used to treat certain mental disorders). Prozac may alter the effect of these medicines on the blood. If Prozac treatment is started or stopped when you are taking warfarin, your doctor will need to perform certain tests, adjust your dose and check on you more frequently.
• cyproheptadine (for allergies); because it may reduce the effect of Prozac.
• drugs that lower sodium levels in the blood (including, drug that causes increase in urination, desmopressin, carbamazepine and oxcarbazepine); because these drugs may increase the risk of sodium levels in the blood becoming too low when taken with Prozac.
• anti-depressants such as tricyclic anti-depressants, other selective serotonin reuptake inhibitors (SSRIs) or bupropion, mefloquine or chloroquine (used to treat malaria), tramadol (used to treat severe pain) or anti-psychotics such as phenothiazines or butyrophenones; because Prozac may increase the risk of seizures when taken with these medicines.
• flecainide, propafenone, nebivolol or encainide (for heart problems), carbamazepine (for epilepsy), atomoxetine or tricyclic antidepressants (for example imipramine, desipramine and amitriptyline) or risperidone (for schizophrenia); because Prozac may possibly change the blood levels of these medicines, your doctor may need to lower their dose when administered with Prozac.
Prozac with food, drink and alcohol
• You can take Prozac with or without food, whatever you prefer.
• You should avoid alcohol while you are taking this medicine. Pregnancy, breast-feeding and fertility
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Pregnancy
Talk to your doctor as soon as possible if you’re pregnant, if you might be pregnant, or if you’re planning to become pregnant.
In babies whose mothers took fluoxetine during the first few months of pregnancy, there have been some studies describing an increased risk of birth defects affecting the heart. In the general population, about 1 in 100 babies are born with a heart defect. This increased to about 2 in 100 babies in mothers who took fluoxetine. When taken during pregnancy, particularly in the last 3 months of pregnancy, medicines like fluoxetine may increase the risk of a serious condition in babies, called persistent pulmonary hypertension of the newborn (PPHN), making the baby breathe faster and appear bluish. These symptoms usually begin during the first 24 hours after the baby is born. If this happens to your baby you should contact your midwife and/or doctor immediately.
It is preferable not to use this treatment during pregnancy unless the potential benefit outweighs the potential risk. Thus, you and your doctor may decide to gradually stop taking Prozac while you are pregnant or before being pregnant. However, depending on your circumstances, your doctor may suggest that it is better for you to keep taking Prozac.
Caution should be exercised when used during pregnancy, especially during late pregnancy or just before giving birth since the following effects have been reported in new born children: irritability, tremor, muscle weakness, persistent crying, and difficulty in sucking or in sleeping.
Breast-feeding
Fluoxetine is excreted in breast milk and can cause side effects in babies. You should only breast-feed if it is clearly necessary. If breast-feeding is continued, your doctor may prescribe a lower dose of fluoxetine.
Fertility
Fluoxetine has been shown to reduce the quality of sperm in animal studies. Theoretically, this could affect fertility, but impact on human fertility has not been observed as yet.
Driving and using machines
Psychotropic drugs such as Prozac may affect your judgment or coordination. Do not drive or use machinery until you know how Prozac affects you.
Prozac contains sucrose and ethanol
Prozac oral solution contains sucrose. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.
The flavouring for this medicinal product contains small amounts of ethanol (alcohol), less than 100 mg per dose (see Section 6).
3. How to take Prozac
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure. Do not take more medicine than your doctor tells you.
Measure the right amount of medicine using the measuring cup, syringe or a measuring spoon, then drink it.
Adults:
The recommended dose is:
• Depression: The recommended dose is 5 ml oral solution (20 mg) daily. Your doctor will review and adjust your dosage if necessary within 3 to 4 weeks of the start of treatment. If required, the dosage can be gradually increased up to a maximum of 15 ml oral solution (60 mg) daily. The dose should be increased carefully to ensure that you receive the lowest effective dose. You may not feel better immediately when you first start taking your medicine for depression. This is usual because an improvement in depressive symptoms may not occur until after the first few weeks. Patients with depression should be treated for at least 6 months.
• Bulimia nervosa: The recommended dose is 15 ml oral solution (60 mg) daily.
• Obsessive-compulsive disorder: The recommended dose is 5 ml oral solution (20 mg) daily. Your doctor will review and adjust your dosage if necessary after 2 weeks of treatment. If required, the dosage can be gradually increased up to a maximum of 15 ml oral solution (60 mg) daily. If no improvement is noted within 10 weeks, your doctor will reconsider your treatment.
Use in children and adolescents aged 8 to 18 years with depression:
Treatment should be started and be supervised by a specialist. The starting dose is 10 mg/day (given as 2.5 ml of Prozac oral solution). After 1 to 2 weeks, your doctor may increase the dose to 20 mg/day. The dose should be increased carefully to ensure that you receive the lowest effective dose. Lower weight children may need lower doses. If there is a satisfactory response to treatment, your doctor will review the need for continuing treatment beyond 6 months. If you have not improved within 9 weeks, your doctor will reassess your treatment.
Elderly:
Your doctor will increase the dose with more caution and the daily dose should generally not exceed 10 ml oral solution (40 mg). The maximum dose is 15 ml oral solution (60 mg) daily.
Liver impairment:
If you have a liver problem or are using other medication that might affect Prozac, your doctor may decide to prescribe a lower dose or tell you to use Prozac every other day.
If you take more Prozac than you should
• If you take too much, go to your nearest hospital emergency department (or casualty) or tell your doctor straight away.
• Take the bottle of Prozac with you if you can.
Symptoms of overdose include: nausea, vomiting, seizures, heart problems (like irregular heart beat and cardiac arrest), lung problems and change in mental condition ranging from agitation to coma.
If you forget to take Prozac
• If you miss a dose, do not worry. Take your next dose the next day at the usual time. Do not take a double dose to make up for a forgotten dose.
• Taking your medicine at the same time each day may help you to remember to take it regularly.
If you stop taking Prozac
• Do not stop taking Prozac without asking your doctor first, even when you start to feel better. It is important that you keep taking your medicine.
• Make sure you do not run out of medicine.
You may notice the following effects (withdrawal effects) when you stop taking Prozac: dizziness; tingling feelings like pins and needles; sleep disturbances (vivid dreams, nightmares, inability to sleep); feeling restless or agitated; unusual tiredness or weakness; feeling anxious; nausea/ vomiting (feeling sick or being sick); tremor (shakiness); headaches.
Most people find that any symptoms on stopping Prozac are mild and disappear within a few weeks. If you experience symptoms when you stop treatment, contact your doctor.
When stopping Prozac, your doctor will help you to reduce your dose slowly over one or two weeks - this should help reduce the chance of withdrawal effects.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
4. Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.
• If you have thoughts of harming or killing yourself at any time, contact your doctor or go to a hospital straight away (see Section 2).
• If you get a rash or allergic reaction such as itching, swollen lips/tongue or wheezing/shortness of breath, stop taking the medicine straight away and tell your doctor immediately.
• If you feel restless and cannot sit or stand still, you may have akathisia; increasing your dose of Prozac may make you feel worse. If you feel like this, contact your doctor.
• Tell your doctor immediately if your skin starts to turn red or you develop a varied skin reaction or your skin starts to blister or peel. This is very rare.
The most frequent sides effects (very common side effects that may affect more than 1 user in 10) are insomnia, headache, diarrhoea, feeling sick (nausea) and fatigue.
Some patients have had:
• a combination of symptoms (known as “serotonin syndrome”) including unexplained fever with faster breathing or heart rate, sweating, muscle stiffness or tremor, confusion, extreme agitation or sleepiness (only rarely);
• feelings of weakness, drowsiness or confusion mostly in elderly people and in (elderly) people taking diuretics (water tablets);
• prolonged and painful erection;
• irritability and extreme agitation;
• heart problems, such as fast or irregular heart rate, fainting, collapsing or dizziness upon standing which may indicate abnormal functioning of the heart rate.
If you have any of the above side effects, you should tell your doctor immediately.
