Relonchem Fluoxetine 20mg Capsules: Depression, OCD & Bulimia UK Guide
Relonchem Fluoxetine 20 mg Capsules contain 20 mg of fluoxetine, a selective serotonin reuptake inhibitor (SSRI) antidepressant used for the treatment of major depressive episodes, obsessive-compulsive disorder (OCD), and bulimia nervosa. Fluoxetine selectively inhibits serotonin reuptake, increasing serotonin availability between nerve cells and supporting neurotransmitter signalling involved in mood and emotional regulation.
For adults, 20 mg once daily is the recommended dose for major depressive episodes and the recommended starting dose for OCD. For bulimia nervosa, the recommended adult dose is 60 mg daily when used as part of a treatment programme that includes psychotherapy. Fluoxetine is generally taken once daily, with or without food, and therapeutic improvement may take several weeks.
What Is Relonchem Fluoxetine 20mg Used For?
- Major Depressive Episodes: Fluoxetine is indicated for the treatment of major depressive episodes in adults. The recommended adult dose is generally 20 mg once daily, although the dose may be adjusted according to individual response and clinical circumstances.
- Obsessive-Compulsive Disorder: Fluoxetine is indicated for the treatment of OCD in adults. The recommended starting dose is generally 20 mg daily, with adjustment considered by the prescriber if the response is insufficient.
- Bulimia Nervosa: Fluoxetine is indicated for bulimia nervosa as a complement to psychotherapy. The recommended adult dose for this indication is 60 mg daily to help reduce binge-eating and purging activity.
- Depression Symptoms: Fluoxetine affects serotonin signalling as part of treatment for depressive illness. Therapeutic improvement develops gradually rather than providing immediate relief.
- Prescription Treatment: Fluoxetine is a prescription-only medicine in the UK. The appropriate dose and treatment duration depend on the condition being treated, treatment response, age and other individual clinical factors.
- Established 20mg Strength: The 20 mg capsule provides an established adult treatment strength for major depressive episodes and is also the recommended starting strength for OCD. Higher doses may be prescribed when clinically appropriate, while bulimia nervosa has a specific recommended adult dose.
The appropriate fluoxetine dose depends on the condition being treated and individual clinical circumstances. For major depressive episodes and OCD, 20 mg once daily is commonly used, while bulimia nervosa has a recommended adult dose of 60 mg daily alongside psychotherapy.
How Does Relonchem Fluoxetine 20mg Work?
Fluoxetine selectively inhibits the reuptake of serotonin by nerve cells in the brain, increasing serotonin availability for signalling between nerve cells. This supports neurotransmitter activity involved in mood and emotional regulation and is relevant to its therapeutic effects in depression, OCD and bulimia nervosa. Fluoxetine does not normally provide immediate therapeutic relief, and patients may need to take it consistently for several weeks before noticeable improvement develops. Fluoxetine and its active metabolite also have relatively long half-lives, meaning they remain in the body for an extended period after dosing.
How to Take Relonchem Fluoxetine 20mg Capsules
- Swallow Whole: Swallow the capsule whole with water. Do not alter the capsule unless your doctor or pharmacist has specifically advised you to do so.
- Adults: For major depressive episodes, the recommended adult dose is generally 20 mg once daily. For OCD, 20 mg daily is generally used as the starting dose, while the recommended adult dose for bulimia nervosa is 60 mg daily alongside psychotherapy.
- Once-Daily Dose: Fluoxetine is generally taken once daily. Take it exactly as prescribed and do not increase, decrease or double the dose without medical advice.
- Special Patient Groups: Dose adjustments or more cautious treatment may be required for some patients, including those with other medical conditions or those taking medicines that interact with fluoxetine.
- Morning or Evening: Fluoxetine may be taken at a time of day recommended by the prescriber. Taking it at approximately the same time each day can help maintain a consistent treatment routine.
- Older Adults: Older patients may require more cautious dose adjustment, particularly when higher doses are being considered. The prescriber will determine the appropriate dose according to individual circumstances.
- With or Without Food: Fluoxetine capsules can generally be taken with or without food. Food does not usually prevent the medicine from being taken as prescribed.
- Treatment Duration: Fluoxetine may take several weeks before therapeutic improvement becomes noticeable. For depression, treatment is generally continued for a sufficient period after recovery to reduce the risk of relapse, with UK product information recommending at least six months after recovery from a depressive episode.
For OCD, treatment should be continued according to the prescribed plan and may require several weeks before a fuller response develops. For bulimia nervosa, the recommended adult dose is 60 mg daily alongside psychotherapy. Do not change the prescribed dose or treatment duration without medical advice.

Important Warnings and Precautions
- MAOIs: Fluoxetine must not be combined with certain monoamine oxidase inhibitors because of the risk of serious reactions. Appropriate intervals may also be required when changing between fluoxetine and an MAOI.
- Serotonin Syndrome: Combining fluoxetine with other medicines that increase serotonergic activity can increase the risk of serotonin syndrome. Symptoms may include agitation, sweating, shaking, muscle twitching, confusion and changes in heart rate.
- Mood Changes: Fluoxetine can cause changes in mood or behaviour in some patients. Unusually elevated mood, increased energy or other symptoms of mania or hypomania should be discussed promptly with a healthcare professional.
- Dependence and Discontinuation: Fluoxetine is not generally associated with dependence in the same way as medicines such as benzodiazepines, but discontinuation symptoms can occur in some patients after stopping treatment.
- Driving and Machinery: Fluoxetine can cause dizziness, drowsiness or blurred vision in some patients. Do not drive, cycle or operate machinery until you know how the medicine affects you.
- Long Half-Life: Fluoxetine and its active metabolite remain in the body for a relatively long period. This can influence how treatment effects, medicine interactions and discontinuation symptoms develop.
- Other Serotonergic Medicines: Other medicines affecting serotonin, including certain antidepressants and other serotonergic treatments, may interact with fluoxetine and increase the risk of serotonin syndrome.
- Bleeding Risk: Fluoxetine may increase the risk of abnormal bleeding, particularly when taken with anticoagulants, antiplatelet medicines or NSAIDs such as aspirin and ibuprofen.
- Gradual Discontinuation: Fluoxetine should not be stopped or changed without medical advice. A healthcare professional can determine whether the dose should be reduced gradually.
- Withdrawal Symptoms: Some patients may experience dizziness, sensory disturbances, sleep problems, anxiety or nausea after stopping fluoxetine. Its long half-life can influence how discontinuation effects develop.
- Other Medicines: Fluoxetine can interact with medicines including metoprolol, tamoxifen, buprenorphine, warfarin and other medicines that affect bleeding or serotonin activity. Always tell your doctor or pharmacist about other medicines and supplements you are taking.
Stopping Relonchem Fluoxetine 20mg Treatment

Although its long half-life can make withdrawal reactions less prominent than with some other antidepressants, discontinuation symptoms can still occur. A prescriber can advise on an appropriate reduction plan and monitor for returning symptoms or other problems during treatment changes.
