1. What is Lafactin and what is it used for

Lafactin contains the active substance venlafaxine. Lafactin is an antidepressant that belongs to a group of medicines called serotonin and norepinephrine reuptake inhibitors (SNRIs). Medicines in this group are used to treat depression and other conditions, such as anxiety disorders. It is believed that in people with depression and/or anxiety, there is a lower concentration of serotonin and norepinephrine in the brain. The mechanism of action of antidepressants is not fully understood, but they may help by increasing the concentration of serotonin and norepinephrine in the brain. Lafactin is used to treat depression in adults. It is also indicated for the treatment of the following anxiety disorders in adults: generalized anxiety disorder, social phobia (fear or avoidance of social situations), and panic disorder (panic attacks). For the patient to feel better, it is essential that the treatment of depression and social phobia is carried out correctly. If the treatment is not started, the patient's condition may not improve, worsen, and become more difficult to treat.

2. Important information before taking Lafactin

When not to take Lafactin:

• If the patient is allergic to venlafaxine or any of the other ingredients of this medicine (listed in section 6).
• If the patient is taking, or has taken within the last 14 days, any irreversible monoamine oxidase inhibitors (MAOIs) used to treat depression or Parkinson's disease. Taking irreversible MAOIs with other medicines, including Lafactin, can cause serious or life-threatening side effects. Also, before starting to take any MAOI, the patient should wait at least 7 days after stopping Lafactin (see also "Serotonin syndrome" and "Lafactin and other medicines").

with MAOIs (see "Important information before taking Lafactin").

Warnings and precautions

Before starting treatment with Lafactin, the patient should discuss it with their doctor or pharmacist.

• If the patient is taking other medicines that may increase the risk of serotonin syndrome when taken with Lafactin (see "Lafactin and other medicines").
• If the patient has eye diseases, such as certain types of glaucoma (increased pressure in the eyeball).
• If the patient has a history of high blood pressure.
• If the patient has a history of heart disease.
• If the patient has a history of heart rhythm disorders.
• If the patient has a history of seizures (epilepsy).
• If the patient has a history of decreased sodium levels in the blood (hyponatremia).
• If the patient has a tendency to bruise or bleed (bleeding disorders in the past), or if the patient is pregnant (see "Pregnancy, breastfeeding, and fertility"), or if they are taking medicines that may increase the risk of bleeding, such as warfarin (used to prevent blood clotting).
• If the patient or anyone in their family has a history of mania or bipolar disorder (feeling overly excited or euphoric).
• If the patient has a history of aggressive behavior.

Lafactin may cause feelings of restlessness or inability to sit or stand still during the first few weeks of treatment. If such symptoms occur, the patient should inform their doctor. Do not drink alcohol during treatment with Lafactin, as it may cause extreme fatigue and loss of consciousness. Taking Lafactin with alcohol and/or certain medicines may worsen symptoms of depression and other conditions, such as anxiety disorders. Suicidal thoughts and worsening of depression or anxiety disorders People with depression and/or anxiety disorders may sometimes think about self-harm or suicide. Such thoughts or behavior may worsen when starting to take antidepressants, as these medicines usually start to work after 2 weeks, sometimes later. These thoughts may also occur when reducing the dose or stopping treatment with Lafactin. The occurrence of suicidal thoughts, self-harm, or suicidal behavior is more likely if:

• the patient has had suicidal thoughts or self-harm in the past;
• the patient is a young adult; clinical trial data indicate an increased risk of suicidal behavior in adults under 25 with mental disorders who were treated with antidepressants.

If the patient experiences suicidal thoughts or self-harm, they should immediately contact their doctor or go to the hospital. It may be helpful to inform relatives or friends about the depression or anxiety disorder and ask them to read the leaflet. The patient may ask relatives or friends for help and ask them to inform them if they notice that the depression or anxiety has worsened or if there are worrying changes in behavior. Dry mouth Dry mouth is reported by 10% of patients treated with venlafaxine. This may increase the risk of tooth decay. Therefore, it is essential to take good care of oral hygiene. Diabetes Venlafaxine may affect blood sugar levels. Therefore, it may be necessary to adjust the doses of antidiabetic medicines. Sexual dysfunction Medicines like Lafactin (so-called SSRIs/SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms may persist even after stopping treatment. Children and adolescents Lafactin should not be used in children and adolescents under 18 years of age. It should also be noted that patients under 18 years of age who take medicines in this group are at increased risk of side effects, such as suicidal attempts, suicidal thoughts, and hostility (especially aggression, rebellious behavior, and expressions of anger). Nevertheless, the doctor may prescribe Lafactin to patients under 18 years of age if they consider it beneficial. If the doctor has prescribed Lafactin to a patient under 18 years of age, in case of any doubts, the patient should consult their doctor to discuss it. The patient should inform their doctor if any of the above symptoms occur or worsen in patients under 18 years of age taking Lafactin. So far, there is no evidence of long-term safety regarding the effects on growth, maturation, and development of cognitive and behavioral functions in this age group.

Lafactin and other medicines

The patient should tell their doctor or pharmacist about all medicines they are taking, have recently taken, or plan to take. The doctor will decide whether to use Lafactin with other medicines. The patient should not start or stop taking other medicines, including over-the-counter medicines, herbal, or natural products, without consulting their doctor or pharmacist.

• Irreversible monoamine oxidase inhibitors used to treat depression or Parkinson's disease should not be taken with Lafactin.The patient should tell their doctor if they have taken these medicines within the last 14 days (MAOIs; see "Important information before taking Lafactin").
• Serotonin syndrome:During treatment with venlafaxine, a potentially life-threatening or neuroleptic malignant syndrome-like reaction may occur, especially when taken with medicines such as:
• triptans (used to treat migraine headaches)
• medicines used to treat depression, such as selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants, or lithium-containing medicines
• medicines containing amphetamines (used to treat attention deficit hyperactivity disorder (ADHD), narcolepsy, and obesity)
• medicines containing linezolid, an antibiotic used to treat infections
• medicines containing reversible MAOIs, such as moclobemide (used to treat depression)
• medicines containing sibutramine (used for weight loss)
• medicines containing tramadol, fentanyl, tapentadol, pethidine, or pentazocine (used to treat severe pain)
• medicines containing dextromethorphan (used to treat cough)
• medicines containing methadone (used to treat opioid dependence or severe pain)
• medicines containing methylene blue (used to treat high levels of methemoglobin in the blood)
• medicines containing St. John's Wort (Hypericum perforatum, herbal or natural products used to treat mild depression)
• medicines containing tryptophan (used for sleep problems and depression)
• antipsychotic medicines (used to treat conditions with symptoms such as hearing, seeing, or feeling things that do not exist, delusions, unnatural suspiciousness, unclear thinking, and withdrawal).
• medicines containing buprenorphine. These medicines may interact with Lafactin and may cause symptoms such as involuntary, rhythmic muscle contractions, including muscles that control eye movements, agitation, hallucinations, coma, excessive sweating, tremors, increased reflexes, muscle tension, and fever above 38°C. If such symptoms occur, the patient should contact their doctor.

Subjective and objective symptoms of serotonin syndrome may include a combination of the following: restlessness, hallucinations, loss of coordination, rapid heart rate, elevated body temperature, rapid changes in blood pressure, hyperreactivity, diarrhea, coma, nausea, vomiting. The most severe form of serotonin syndrome may resemble neuroleptic malignant syndrome. Its subjective and objective symptoms include fever, rapid heart rate, sweating, muscle stiffness, disorientation, increased enzyme activity in muscles (detected in blood tests). If serotonin syndrome is suspected, the patient should immediately contact their doctor or go to the hospital.

If the patient is taking medicines that may affect heart rhythm, they should tell their doctor.

Examples of such medicines:

• Antiarrhythmic medicines, such as quinidine, amiodarone, sotalol, or dofetilide (used to treat heart rhythm disorders).
• Antipsychotic medicines, such as thioridazine (see above - "Serotonin syndrome").
• Antibiotics, such as erythromycin or moxifloxacin (used to treat bacterial infections).
• Antihistamines (used to treat allergies).

The following medicines may also interact with Lafactin, and the patient should use them with caution. It is particularly important to inform the doctor if the patient is taking medicines containing:

• ketokonazole (an antifungal medicine)
• haloperidol or risperidone (medicines used to treat mental disorders)
• metoprolol (a beta-blocker used to treat high blood pressure and heart disease).

Lafactin with food, drink, and alcohol

Lafactin should be taken with food (see section 3 "How to take Lafactin"). Do not drink alcohol during treatment with Lafactin. Taking Lafactin with alcohol may cause extreme fatigue and loss of consciousness, as well as worsen symptoms of depression and other conditions, such as anxiety disorders.

Pregnancy and breastfeeding

If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor or pharmacist before taking this medicine. Lafactin should only be used after discussing the potential benefits and risks to the unborn child with the doctor. The patient should ensure that their midwife and/or doctor know that they are taking Lafactin. Similar medicines (from the SSRI group) taken by women during pregnancy may increase the risk of a severe condition in the baby called persistent pulmonary hypertension of the newborn (PPHN), which causes rapid breathing and blue discoloration of the baby's skin. These symptoms usually occur within the first day of life. If this happens, the patient should immediately contact their midwife and/or doctor. If the patient takes this medicine during pregnancy, after birth, the baby may experience difficulties with breathing, as well as other symptoms, such as poor feeding. If the patient is concerned about such symptoms in their newborn, they should contact their doctor and/or midwife, who will be able to provide appropriate advice. If the patient takes Lafactin at the end of pregnancy, there may be an increased risk of severe bleeding from the vagina shortly after delivery, especially if they have a history of bleeding disorders. The patient's doctor or midwife should know that they are taking Lafactin so that they can provide advice. Venlafaxine passes into breast milk. There is a risk of affecting the baby. Therefore, the patient should discuss this with their doctor, and the doctor will decide whether to stop breastfeeding or stop treatment with Lafactin.

Driving and using machines

The patient should not drive or operate machinery until they know how Lafactin affects them.

Lafactin capsules contain sugar

If the patient has been informed by their doctor that they have an intolerance to some sugars, they should contact their doctor before taking this medicine.

Lafactin contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per dose, which means it is essentially "sodium-free".

3. How to take Lafactin

This medicine should always be taken as directed by the doctor. In case of doubts, the patient should consult their doctor or pharmacist. The usual recommended starting dose for the treatment of depression, generalized anxiety disorder, and social phobia is 75 mg per day. This dose may be gradually increased by the doctor if necessary, up to a maximum dose of 375 mg per day in the case of depression. For panic disorder, treatment should be started with a lower dose (37.5 mg) and then gradually increased. The maximum dose for the treatment of generalized anxiety disorder, social phobia, and panic disorder is 225 mg per day. Lafactin should be taken once daily, at approximately the same time, regardless of whether the medicine is taken in the morning or evening. The capsules should be swallowed whole, with a drink of water. They should not be divided, crushed, chewed, or dissolved. Lafactin should be taken with food. The patient should inform their doctor about any liver or kidney problems, as a dose adjustment may be necessary. The patient should not stop taking Lafactin without consulting their doctor (see "Stopping treatment with Lafactin").

Taking a higher dose of Lafactin than recommended

If the patient has taken a higher dose of Lafactin than recommended, they should immediately contact their doctor or pharmacist. Overdose can be life-threatening, especially when taken with alcohol and/or certain medicines (see "Lafactin and other medicines"). Symptoms of possible overdose may include rapid heart rate, changes in consciousness (from drowsiness to coma), changes in vision, seizures, or vomiting.

Missing a dose of Lafactin

If the patient misses a dose, they should take it as soon as possible. However, if it is almost time for the next dose, they should skip the missed dose and take only one dose at the usual time. The patient should not take a double dose to make up for the missed dose. The patient should not take a higher dose in one day than the daily dose of Lafactin prescribed by their doctor.

Stopping treatment with Lafactin

The patient should not stop treatment or reduce the dose without consulting their doctor, even if they feel better. If the doctor decides that it is possible to stop taking Lafactin, they will inform the patient how to gradually reduce the dose before completely stopping treatment. In patients stopping Lafactin, especially when treatment is stopped abruptly or the dose is reduced too quickly, side effects may occur, such as suicidal thoughts, aggression, fatigue, dizziness, headache, insomnia, nightmares, dry mouth, loss of appetite, nausea, diarrhea, nervousness, agitation, disorientation, ringing in the ears, tingling or numbness, or rarely, a feeling of electric shock, weakness, sweating, seizures, or flu-like symptoms. The doctor will advise how to gradually stop taking Lafactin. This may take several weeks or months. In some patients, it may be necessary to stop the medicine gradually over several months or longer. If any of the above symptoms occur or worsen, the patient should consult their doctor. In case of any further doubts about taking this medicine, the patient should consult their doctor or pharmacist.

4. Possible side effects

Like all medicines, Lafactin can cause side effects, although not everybody gets them. If the patient experiences any of the following side effects, they should stop taking Lafactin and immediately contact their doctor or go to the hospitalemergency department:

Uncommon (may affect up to 1 in 100 people)
