1. What is Venlafaxine Retard Krka and what is it used for

Venlafaxine Retard Krka contains the active substance venlafaxine.

Venlafaxine Retard Krka 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. Antidepressants are not fully understood, but they may help to increase the levels of serotonin and noradrenaline in the brain.

Venlafaxine Retard Krka is a treatment for adults with depression. Venlafaxine Retard Krka is also a treatment for adults with the following anxiety disorders: generalized anxiety disorder, social anxiety disorder (fear or avoidance of social situations) and panic disorder (panic attacks). Treating depressive and anxiety disorders adequately is important to help you feel better. If left untreated, your condition may not improve or may get worse and become more difficult to treat.

2. What you need to know before you take Venlafaxine Retard Krka

Do not take Venlafaxine Retard Krka

• 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 with Venlafaxine Retard Krka can cause serious or even life-threatening side effects. Also, you must wait at least 7 days after you stop taking Venlafaxine Retard Krka before you take any irreversible MAOI (see also the section “Other medicines and Venlafaxine Retard Krka” and the information in that section about “Serotonin Syndrome”).

Warnings and precautions

Consult your doctor or pharmacist before you start taking Venlafaxine Retard Krka:

• If you are taking other medicines that, when taken with Venlafaxine Retard Krka, could increase the risk of developing serotonin syndrome (see the section “Other medicines and Venlafaxine Retard Krka”)
• If you have eye problems, such as certain types 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 irregular heart rhythm
• If you have a history of seizures (fits)
• If you have a history of low sodium levels in your blood (hyponatremia)
• If you have a tendency to develop bruises or have a tendency to bleed easily (history of bleeding disorders), if you are pregnant (see Pregnancy, breast-feeding and fertility) or if you are using other medicines that may increase the risk of bleeding, e.g., warfarin (used to prevent blood clots)
• If your cholesterol levels increase
• If you have a history of, or if someone in your family has had, mania or bipolar disorder (feeling overexcited or elated)
• If you have a history of aggressive behavior

Venlafaxine Retard Krka may cause a feeling of restlessness or difficulty sitting or standing still during the first few weeks of treatment. You should consult your doctor if this happens to you.

Do not drink alcohol while you are taking venlafaxine, as it may cause extreme drowsiness and unconsciousness. Taking it with certain medicines or alcohol may worsen the symptoms of depression and other conditions, such as anxiety disorders.

Suicidal thoughts and worsening of your depression or anxiety disorder

If you are depressed and/or have an anxiety disorder, you may sometimes have thoughts of harming or killing yourself. These thoughts may increase when you first start taking antidepressants, because all these medicines take time to work, usually around 2 weeks, but sometimes longer. These thoughts may also occur when your dose is reduced or when you stop taking Venlafaxine Retard Krka.

This is more likely to happen:

• If you have previously had thoughts of suicide or self-harm.
• If you are a young adult. Information from clinical trials has shown an increased risk of suicidal behavior 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 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 behavior.

Sexual dysfunction

Some medicines of the same group as Venlafaxine Retard Krka (called SSRIs/ SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms have persisted after stopping treatment.

Dry mouth

Dry mouth has been reported in 10% of patients treated with venlafaxine. This may increase the risk of tooth decay. Therefore, you should be careful with your dental hygiene.

Diabetes

Blood glucose levels may be altered due to Venlafaxine Retard Krka. Therefore, it may be necessary to adjust the dosage of your diabetes medicines.

Children and adolescents

Venlafaxine Retard Krka should not normally be used in the treatment of children and adolescents under 18 years of age. Also, you should know that in patients under 18 years of age, there is an increased risk of adverse effects such as suicide attempt, suicidal ideation, and hostility (predominantly aggression, confrontation, and irritability) when they take this type of medicine. Despite this, your doctor may prescribe this medicine to patients under 18 years of age when he decides that it is the best option for the patient. If your doctor has prescribed this medicine to a patient under 18 years of age and you want to discuss this, please go back to your doctor. You should inform your doctor if any of the above symptoms develop or worsen when these patients under 18 years of age are taking Venlafaxine Retard Krka. Also, the long-term effects of this medicine on safety, regarding growth, maturation, and cognitive and behavioral development, have not yet been demonstrated.

Other medicines and Venlafaxine Retard Krka

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Your doctor will decide whether you can take Venlafaxine Retard Krka with other medicines.

Do not start or stop taking any medicines, including those bought without a prescription, herbal or natural remedies, before checking with your doctor or pharmacist.

• MAOIs used to treat depression or Parkinson’s disease should not be taken with Venlafaxine Retard Krka. Tell your doctor if you have taken these medicines in the last 14 days. (MAOI: see section “What you need to know before you take Venlafaxine Retard Krka”)
• Serotonin syndrome: a potentially life-threatening or severe reaction, or a condition called neuroleptic malignant syndrome (NMS) (see section “Possible side effects”), may occur with venlafaxine treatment, particularly when taken with other medicines. Examples of these medicines include:

• triptans (used for migraine)
• other medicines for treating depression, for example, SNRIs, SSRIs, tricyclic antidepressants, or medicines containing lithium
• medicines containing amphetamines (used to treat attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity)
• medicines containing the antibiotic linezolid (used to treat infections)
• medicines containing moclobemide, a reversible MAOI (used to treat depression)
• medicines containing sibutramine (used for weight loss)
• medicines containing opioids (for example, buprenorphine, tramadol, fentanyl, tapentadol, pethidine, or pentazocine) used to treat severe pain
• medicines containing dextromethorphan (used to treat coughs)
• medicines containing methadone (used for opioid addiction or for severe pain treatment)
• medicines containing methylene blue (used to treat high levels of methemoglobin in the blood)
• products containing St John’s Wort (also known as Hypericum perforatum, a herbal or natural remedy used to treat mild depression)
• products containing tryptophan (used for problems such as sleep and depression)
• antipsychotics (used to treat a disease with symptoms such as hearing, seeing, or feeling things that are not there, mistaken beliefs, unusual suspiciousness, lack of clarity in reasoning, and withdrawal syndrome)

The signs and symptoms of serotonin syndrome may include a combination of the following: restlessness, hallucinations, loss of coordination, rapid heartbeat, increased body temperature, rapid changes in blood pressure, overactive reflexes, diarrhea, coma, nausea, vomiting.

In its most severe form, serotonin syndrome can resemble neuroleptic malignant syndrome (NMS). The signs and symptoms of NMS may include a combination of fever, rapid heartbeat, sweating, rigid muscles, confusion, and increased muscle enzymes (determined by a blood test).

Tell your doctor immediately, or go to the casualty department of your nearest hospital, if you think you are experiencing serotonin syndrome.

Tell your doctor if you are taking medicines that may affect your heart rhythm.

Some examples of these medicines include:

• anti-arrhythmics such as quinidine, amiodarone, sotalol, or dofetilide (used to treat irregular heartbeat)
• antipsychotics such as thioridazine (see also serotonin syndrome above)
• antibiotics such as erythromycin or moxifloxacin (used to treat bacterial infections)
• antihistamines (used to treat allergies)

The following medicines may also interact with Venlafaxine Retard Krka 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 (for treating psychiatric conditions)
• metoprolol (a beta-blocker for treating high blood pressure and heart problems)

Taking Venlafaxine Retard Krka with food, drinks, and alcohol

Venlafaxine Retard Krka should be taken with food (see section 3 “How to take Venlafaxine Retard Krka”).

Do not drink alcohol while you are taking venlafaxine. Taking it with alcohol may cause extreme drowsiness and unconsciousness, and may worsen the symptoms of depression and other conditions, such as anxiety disorders.

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. You should only take Venlafaxine Retard Krka after discussing the potential benefits and risks with your doctor.

If you take Venlafaxine Retard Krka during the late stage of pregnancy, there is a risk of an increased chance of bleeding in the womb, especially if you have a history of bleeding disorders. Your doctor or midwife should know that you are taking Venlafaxine Retard Krka so they can advise you.

Make sure your midwife and/or doctor knows you are taking Venlafaxine Retard Krka. When similar medicines (SSRIs) are taken during pregnancy, there is a potential increased risk of a condition called persistent pulmonary hypertension in the newborn (PPHN), which makes the baby breathe faster and appear blue. These symptoms usually start 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 breathing problems, other symptoms your baby may have when it is born are problems with feeding. If your baby has these symptoms when it is born and you are worried, contact your doctor and/or midwife who will be able to advise you.

Venlafaxine Retard Krka passes into breast milk. There is a risk of an effect on the baby. Therefore, you should discuss this with your doctor, and he will decide whether you should stop breast-feeding or stop Venlafaxine Retard Krka.
