1. What Efexor XL is and what it is used for
Efexor XL contains the active substance venlafaxine. Efexor XL is an antidepressant that belongs to a group of medicines called serotonin and norepinephrine reuptake inhibitors (SNRIs). This group of medicines is used to treat depression and other conditions such as anxiety disorders. It is thought that people who are depressed and/or anxious have lower levels of serotonin and noradrenaline in the brain. It is not fully understood how antidepressants work, but they may help by increasing the levels of serotonin and noradrenaline in the brain.
Efexor XL is a treatment for adults with depression. It is also a treatment for adults with the following anxiety disorders: generalised anxiety disorder, social anxiety disorder (fear or avoidance of social situations) and panic disorder (panic attacks). Treating depression or anxiety disorders properly is important to help you get better. If it is not treated, your condition may not go away and may become more serious and more difficult to treat.
2. What you need to know before you take Efexor XL
Do not take Efexor XL
• If you are allergic to venlafaxine or any of the other ingredients of this medicine (listed in section 6).
• If you are also taking, or have taken within the last 14 days, any medicines known as irreversible monoamine oxidase inhibitors (MAOIs), used to treat depression or Parkinson's disease. Taking an irreversible MAOI together with Efexor XL, can cause serious or even life-threatening side effects. Also, you must wait at least 7 days after you stop taking Efexor XL before you take any MAOI (see also the section entitled “Other medicines and Efexor XL” and the information in that section about ‘Serotonin Syndrome').
Warnings and precautions
Talk to your doctor or pharmacist before taking Efexor XL:
• If you use other medicines that taken together with Efexor XL could increase the risk of developing serotonin syndrome (see the section “Other medicines and Efexor XL”).
• If you have eye problems, such as certain kinds of glaucoma (increased pressure in the eye).
• If you have a history of high blood pressure.
• If you have a history of heart problems.
• If you have been told you have an abnormal heart rhythm.
• If you have a history of fits (seizures).
• If you have a history of low sodium levels in your blood (hyponatraemia).
• If you have a tendency to develop bruises or a tendency to bleed easily (history of bleeding disorders), or if you are taking other medicines that may increase the risk of bleeding e.g., warfarin (used to prevent blood clots).
• If you have a history of, or if someone in your family has had, mania or bipolar disorder (feeling overexcited or euphoric).
• If you have a history of aggressive behaviour.
Efexor XL may cause a sensation of restlessness or an inability to sit or stand still during the first few weeks of treatment. You should tell your doctor if this happens to you.
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 you first start taking 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 yourself or harming yourself.
• If you are a young adult. Information from clinical trials has shown an increased risk of suicidal behaviour in young adults (less than 25 years old) 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.
Dry mouth
Dry mouth is reported in 10% of patients treated with venlafaxine. This may increase the risk of tooth decay (caries). Therefore, you should take special care in your dental hygiene.
Diabetes
Your blood glucose levels may be altered due to Efexor XL. Therefore, the dosage of your diabetes medicines may need to be adjusted.
Children and adolescents
Efexor XL should normally not be used for children and adolescents under 18 years. Also, you should know that 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. Despite this, your doctor may prescribe this medicine for patients under 18 because he/she decides that this is in their best interests. If your doctor has prescribed this medicine 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 Efexor XL. Also, the long-term safety effects concerning growth, maturation and cognitive and behavioural development of this medicine in this age group has not yet been demonstrated.
Other medicines and Efexor XL
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Your doctor should decide whether you can take Efexor XL with other medicines.
Do not start or stop taking any medicines, including those bought without a prescription, natural and herbal remedies, before checking with your doctor or pharmacist.
• Monoamine oxidase inhibitors which are used to treat depression or Parkinson's disease must not be taken with Efexor XL. Tell your doctor if you have taken these medicines within the last 14 days. (MAOIs: see the section “What you need to know before you take Efexor XL”).
• Serotonin syndrome:
A potentially life-threatening condition or Neuroleptic Malignant Syndrome (NMS)-like reactions (see the section “Possible Side Effects”), may occur with venlafaxine treatment, particularly when taken with other medicines.
Examples of these medicines include:
0 Triptans (used for migraine)
0 Other medicines to treat depression, for instance SNRIs, SSRIs, tricyclics, or medicines containing lithium
0 Medicines containing linezolid, an antibiotic (used to treat infections)
0 Medicines containing moclobemide, a MAOI (used to treat depression)
0 Medicines containing sibutramine (used for weight loss)
0 Medicines containing tramadol, fentanyl, tapentadol, pethidine, or pentazocine (used to treat severe pain)
0 Medicines containing dextromethorphan (used to treat coughing)
0 Medicines containing methadone (used to treat opioid drug addiction or severe pain)
0 Medicines containing methylene blue (used to treat high levels of methaemoglobin in the blood)
0 Products containing St. John's Wort (also called Hypericum perforatum, a natural or herbal remedy used to treat mild depression)
0 Products containing tryptophan (used for problems such as sleep and depression)
0 Antipsychotics (used to treat a disease with symptoms such as hearing, seeing or sensing things which are not there, mistaken beliefs, unusual suspiciousness, unclear reasoning and becoming withdrawn)
Signs and symptoms of serotonin syndrome may include a combination of the following: restlessness, hallucinations, loss of coordination, fast heart beat, increased body temperature, fast changes in blood pressure, overactive reflexes, diarrhoea, coma, nausea, vomiting.
In its most severe form, serotonin syndrome can resemble Neuroleptic Malignant Syndrome (NMS).
Signs and symptoms of NMS may include a combination of fever, fast heart beat, sweating, severe muscle stiffness, confusion, increased muscle enzymes (determined by a blood test).
Tell your doctor immediately, or go to the casualty department at your nearest hospital if you think serotonin syndrome is happening to you.
You must tell your doctor if you are taking medicines that can affect your heart rhythm.
Examples of these medicines include:
• Antiarrhythmics such as quinidine, amiodarone, sotalol or dofetilide (used to treat abnormal heart rhythm)
• Antipsychotics such as thioridazine (See also Serotonin syndrome above)
• Antibiotics such as erythromycin or moxifloxacin (used to treat bacterial infections)
• Antihistamines (used to treat allergy)
The following medicines may also interact with Efexor XL and should be used with caution. It is especially important to mention to your doctor or pharmacist if you are taking medicines containing:
• Ketoconazole (an antifungal medicine)
• Haloperidol or risperidone (to treat psychiatric conditions)
• Metoprolol (a beta blocker to treat high blood pressure and heart problems)
Efexor XL with food, drink and alcohol Efexor XL should be taken with food (see section 3 “How to take Efexor XL”).
You should avoid alcohol while you are taking Efexor XL.
Pregnancy and breast-feeding
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.
You should use Efexor XL only after discussing the potential benefits and the potential risks to your unborn child with your doctor.
Make sure your midwife and/or doctor knows you are on Efexor XL. When taken during pregnancy, similar drugs (SSRIs) 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.
If you are taking this medicine during pregnancy, in addition to having trouble breathing, another symptom your baby might have when it is born is not feeding properly. If your baby has these symptoms when it is born and you are concerned, contact your doctor and/or midwife who will be able to advise you.
Efexor XL passes into breast milk. There is a risk of an effect on the baby. Therefore, you should discuss the matter with your doctor, and he/she will decide whether you should stop breast-feeding or stop the therapy with this medicine.

Signs and symptoms of NMS may include a combination of fever, fast heart beat, sweating, severe muscle stiffness, confusion, increased muscle enzymes (determined by a blood test).
• Signs of infection, such as high temperature, chills, shivering, headaches, sweating, flu-like symptoms. This may be the result of a blood disorder which leads to an increased risk of infection.
• Severe rash, which may lead to severe blistering and peeling of the skin.
• Unexplained muscle pain, tenderness or weakness. This may be a sign of rhabdomyolysis.
Other side effects that you should tell your doctor about include (The frequency of these side effects are included in the list “Other side effects that may occur” below):
• Coughing, wheezing and shortness of breath which may be accompanied by a high temperature
• Black (tarry) stools or blood in stools

• Prolonged bleeding - if you cut or injure yourself, it may take slightly longer than usual for bleeding to stop.
Do not be concerned if you see small white balls or granules in your stools after taking this medicine. Inside Efexor XL capsules are spheroids (small white balls) that contain the active ingredient (venlafaxine). These spheroids are released from the capsule into your stomach. As they travel through your stomach and intestines, venlafaxine is slowly released. The spheroid “shell” does not dissolve and is passed out in your stools. So, even though you may see spheroids in your stools, your dose of medicine has been absorbed.
