What ENLAFAX-XR is used for
Enlafax-XR capsules contain an active ingredient called “venlafaxine hydrochloride”.
This medicine is used in the treatment and prevention of relapse of depression and in the treatment of social phobia (social anxiety disorder).
It belongs to a class of medications for depression and anxiety, called Serotonin-Noradrenaline Reuptake Inhibitors (SNRIs).
Serotonin and noradrenaline are chemical messengers that allow certain nerves in brain to work. Enlafax-XR capsules increase the level of these two messengers. Experts think this is how it helps to restore your feeling of wellness.
Depression is longer lasting or more severe than the ‘low moods’ that everyone has from time to time. It is thought to be caused by a chemical imbalance in parts of the brain. This imbalance affects your whole body and can cause emotional and physical symptoms such as feeling low in spirit, lose interest in usual activities, be unable to enjoy life, have poor appetite or over eat, have disturbed sleep, often waking up early, loss of sex drive, low energy and feel guilty over nothing.
Social phobia is a fear of being embarrassed, judged or evaluated negatively in social situations, which can result in substantial impairment in the person’s social emotional, interpersonal and occupational life.
Depression and anxiety are treatable illnesses. Anxiety and tension associated with the normal stress of daily life usually does not require treatment with medicines.
There is no evidence that Enlafax-XR is addictive.
Ask your doctor if you have any questions about why Enlafax-XR has been prescribed for you.
Your doctor may have prescribed Enlafax-XR capsules for another purpose.
Before you take ENLAFAX-XR
When you must not take it
Do not take Enlafax-XR if you are taking other medications for depression known as monoamine oxidase inhibitors, even if you have stopped taking them now, but have taken them within the last 14 days.
Do not take Enlafax-XR if you are allergic to it or to any of the ingredients listed at the end of this leaflet.
Some of the symptoms of an allergic reaction may include:
Itching or hives on the skin
Swelling of the face, lips, tongue or other parts of the body
Shortness of breath, wheezing or troubled breathing; difficulty swallowing
Do not give Enlafax-XR to children or adolescents under 18 years of age.
The safety and effectiveness of Enlafax-XR in this age group have not been established.
Do not take Enlafax-XR after the expiry date printed on the pack.
If you take this medicine after the expiry date has passed, it may not work as well as it should.
Do not take Enlafax-XR if the packaging is torn or show signs of tampering.
If it has expired or is damaged, return it to your pharmacist for disposal.
If you are not sure whether you should start taking this medicine, talk to your doctor.
Before you start to take it
Tell your doctor or pharmacist if you are allergic to the active ingredient or any of the other ingredients listed at the end of this leaflet.
Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.
Tell your doctor or pharmacist if you are pregnant or intend to become pregnant.
Enlafax-XR is not recommended for use during pregnancy. Your doctor will discuss the risks and benefits of using Enlafax-XR if you are pregnant. One of these risks is that newborn babies whose mothers have been taking Enlafax-XR in the last few months of pregnancy, may experience problems soon after delivery, including breathing difficulties, seizures and lack of oxygen in their blood.
If you take Enlafax-XR or similar anti-depressants mid to late in your pregnancy, you may develop a condition known as “pre-eclampsia”, which is characterised by persistent high blood pressure during or after pregnancy. Symptoms of pre-eclampsia can include headaches, abdominal pain, shortness of breath or burning around the sternum, nausea and vomiting, confusion, heightened state of anxiety, and/or visual disturbances such as oversensitivity to light, blurred vision, or seeing flashing spots or auras.
If you take Enlafax-XR or similar antidepressants in the last month of your pregnancy, you may experience heavy bleeding during and/or after delivery.
Continuing treatment with Enlafax-XR or similar antidepressants during pregnancy should be strictly as directed by your doctor. Symptoms of a relapse may occur if treatment is discontinued, even if major depression was previously under control.
Tell your doctor or pharmacist if you are breast-feeding or planning to breast-feed.
Enlafax-XR passes into breast milk and there is a possibility that the breast-fed baby may be affected. For this reason, the use of Enlafax-XR is not recommended in breast-feeding women.
Tell your doctor if you have or have had any, medical conditions, especially the following:
A history of fits (seizures or convulsions)
A personal history or family history of bipolar disorder
A history of aggression
Blood pressure problems
Glaucoma (increased pressure in the eye)
A tendency to bleed more than normal or you are taking medicines to prevent blood clots
A history of restlessness or difficulty sitting still
Raised cholesterol levels or you are taking medicines to lower cholesterol
Problems with your kidneys or liver
Problems with your heart, especially conditions causing irregular heartbeats.
Your doctor may wish to do some heart tests such as an electrocardiogram (ECG) or blood tests during treatment with Enlafax-XR.
Tell your doctor if you plan to have surgery.
If you have not told your doctor about any of the above, tell them before you take Enlafax-XR.
Taking other medicines
Tell your doctor or pharmacist if you take any other medicines, including any that you buy without a prescription from a pharmacy, supermarket or health food shop, such as St John’s Wort or tryptophan supplements.
Do not start to take any other medicine while you are taking Enlafax-XR, unless it is prescribed or approved by your doctor.
Some medicines and Enlafax-XR may interfere with each other. These include:
Medications for depression known as monoamine oxidase inhibitors (such as moclobemide, linezolid, phenelzine and tranylcypromine), even if you have stopped taking them now, but have taken them within the last 14 days. Your doctor or pharmacist can tell you what to do if you are taking any of these medicines.

Haloperidol, risperidone, lithium or clozapine (used to treat mental disorders).
Triptans (used to treat migraine).
Cimetidine (used to treat reflux and stomach ulcers)
Amiodarone or quinidine (used to treat irregular heartbeats)
Tramadol, fentanyl, tapentadol, pethidine, methadone and pentazocine (a pain killer).
Amphetamines (used to treat attention deficit hyperactivity disorder or ADHD)
Your doctor may wish to do some heart tests such as an electrocardiogram (ECG) or blood tests if you are using either of these medicines whilst taking Enlafax-XR.
Medicines used to prevent blood clotting such as anti-coagulants and platelet inhibitors (e.g. warfarin).
Indinavir (an antiviral)
Medications for weight loss, including sibutramine
Erythromycin and linezolid (used to treat infections)
Ketoconazole or fluconazole (used as antifungal medicines)
Metoprolol (used to treat high blood pressure or angina).
These medicines may be affected by Enlafax-XR or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines. Your doctor will advise you.

How to take ENLAFAX-XR
DO NOT DIVIDE, CRUSH, CHEW OR DISSOLVE.
Enlafax-XR capsules are to be swallowed whole and are not be divided, chewed or crushed.
Taking divided, chewed or crushed Enlafax-XR capsules, in theory, could lead to the rapid release and absorption of venlafaxine.
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
The usual starting dose is 75mg taken once daily. If necessary, after two weeks, your doctor may increase your dose.
Do not change dose unless your doctor tells you to.
If you have kidney or liver problems, you may need a lower dose of Enlafax-XR.
If you have heart problems and your doctor wishes to increase your dose of Enlafax-XR, your doctor may first do some blood tests or heart tests such as an electrocardiogram (ECG).
When to take it
Enlafax-XR should be taken once daily with food, at approximately the same time each day.
This could be either in the morning of in the evening.
Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
Avoid drinking alcohol while you are using Enlafax-XR.
Your doctor may have switched your treatment from Venlafaxine Hydrochloride tablets to Enlafax-XR capsules. If this happens, your doctor will normally prescribe a dose that is equivalent to your total daily dose of tablets. The dose of Enlafax-XR capsules should be taken only once daily.
If you forget to take it
If it is less than 12 hours until your next dose, skip the dose you missed and then take your next dose when you are meant to. Otherwise, take it as soon as you remember, and then go back to taking as you would normally.
Do not take a double dose to make up for the dose you missed. Contact your doctor if you have missed more than two doses in a row.
Always finish the capsules you are taking in the current pack before you start a new pack.
If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.
How long to take it for
The length of treatment will depend on how quickly your symptoms improve. Most antidepressants take time to work, so don’t be discouraged if you don’t feel better right away. Some of your symptoms may improve in 1 or 2 weeks but it can take up to another few weeks to feel any real improvement.
Even when you feel well, you will usually have to take Enlafax-XR for several months or even longer to make sure the benefits will last. Discuss this with your doctor and don’t stop taking Enlafax-XR until gaining your doctor’s agreement.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much ENLAFAX-XR. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention. Keep telephone numbers for these places handy. Take the pack of capsules/tablets with you to the doctor or hospital.
If you take too many Enlafax-XR capsules you may:
Have an increased heart rate or changes in heart rhythm
Have a seizure (fits)
Have breathing difficulties
Have dilated pupils.

Things you must do
Visit your doctor regularly for a check up so that your progress can be checked.

Always discuss any questions you have about Enlafax-XR capsules with your doctor.
If you are going to have a surgery, tell your doctor that you are taking this medicine.
Some agents used to assist your doctor during surgery may interact with Enlafax-XR leading to unwanted side effects.

Sometimes people with depression can experience a worsening of their depressive symptoms. This can happen even when taking an antidepressant.
Information from clinical trials has suggested that children, adolescents and young adults (18-24 years), particularly those with depression, may be at increased risk of suicidal behaviour (including suicide attempts) when treated with ENLAFAX-XR, especially during initial treatment.
