DESVENLAFAXINE STADA 50 mg PROLONGED-RELEASE TABLETS

2. What you need to know before you take Desvenlafaxine Stada

Do not take Desvenlafaxine Stada:

• if you are allergic to desvenlafaxine, 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 monoamine oxidase inhibitors (MAOIs) used to treat depression, infections, or Parkinson's disease. Taking an MAOI (e.g., linezolid or methylene blue) with other medicines like desvenlafaxine may cause serious or potentially life-threatening side effects. Additionally, you must wait at least 7 days after stopping desvenlafaxine before taking any MAOI (see also sections "Serotonin Syndrome" and "Other medicines").

Warnings and precautions

Tell your doctor if you have had any of the following conditions before starting to take desvenlafaxine or if they appear during treatment with desvenlafaxine:

• if you or someone in your family has a history of or has had mania (a state of excitement, feeling of euphoria, or hyperirritability) or bipolar disorder (extreme mood changes, e.g., from depression to euphoria).
• if you have a history of aggressive behavior.
• 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 or hypertension.
• if you have a history of heart problems or heart attack.
• if you have a history of seizures (convulsions).
• if you have a history of bleeding disorders (tendency to develop bruises), or if you are pregnant (see section Pregnancy, breastfeeding, and fertility) or if you are using non-steroidal anti-inflammatory drugs (NSAIDs), aspirin, and other medicines that may increase the risk of bleeding when used at the same time as desvenlafaxine.
• if you have a history of kidney problems.
• if you have a history of low sodium levels in the blood (hyponatremia).
• if you have a history of high cholesterol, or if your cholesterol levels increase.
• if you experience the following side effects: agitation (excitability and restlessness), altered consciousness, confusion, coma, palpitations, increased blood pressure, elevated body temperature, excessive sweating, lack of coordination, muscle spasms or stiffness, tremors, nausea, vomiting, and diarrhea. Contact your doctor immediately, as you may be suffering from serotonin syndrome (a disorder that can be serious and, in rare cases, potentially life-threatening).
• if treatment is stopped abruptly, withdrawal symptoms may occur (e.g., mood changes, irritability, agitation, dizziness, anxiety, confusion, headache, sleep disturbances, ringing in the ears, seizures, vision problems, and hypertension). Therefore, it is essential to reduce the dose of desvenlafaxine gradually and under medical supervision, whenever you and your doctor decide to stop treatment.

Some medicines in the same group as desvenlafaxine (called SSRIs/SNRIs) may cause symptoms of sexual dysfunction (see section 4). In some cases, these symptoms persist after stopping treatment.

Suicidal thoughts and worsening of your depression or anxiety disorder

If you are depressed and/or have anxiety disorders, you may sometimes have thoughts of harming yourself or suicide. These thoughts may increase when you first start taking antidepressants, as these medicines take time to work, usually around two weeks, but sometimes longer.

You may be more likely to think this way:

• If you have previously had thoughts of suicide or self-harm.
• If you are a young adult. Clinical trial data has shown an increased risk of suicidal behavior in young adults (less than 25 years of age) with psychiatric disorders who were treated with antidepressants.

If you have thoughts of self-harm or suicide at any time, contact your doctor or go to a hospital immediately.

You may find it helpful to tell a relative or close friendthat 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.

Dry mouth

Dry mouth has been reported in 18% of patients treated with desvenlafaxine. This may increase the risk of tooth decay. Therefore, you should be careful with your oral hygiene.

Elderly patients

In some elderly patients, it cannot be ruled out that they may be more sensitive to desvenlafaxine.

Children and adolescents

Desvenlafaxine should not normally be used in children and adolescents. Additionally, you should know that in patients under 18 years of age, there is a greater risk of side effects such as suicidal attempts, hostility (mainly aggression, confrontational behavior, and irritability) when taking this type of medicine. Nevertheless, your doctor may prescribe this medicine to patients under 18 years of age when they decide it is the most convenient for the patient. If your doctor has prescribed this medicine to a patient under 18 years of age and you wish to discuss this decision, 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 desvenlafaxine. Additionally, the long-term effects on safety, growth, maturity, and cognitive and behavioral development of this medicine have not yet been demonstrated.

Using Desvenlafaxine Stada with other medicines

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.

It is especially important that you tell your doctor if you are taking any of the following medicines:

• monoamine oxidase inhibitors (MAOIs), e.g., medicines containing linezolid (an antibiotic used to treat infections) and methylene blue (see section "Do not take Desvenlafaxine Stada").
• other medicines that contain venlafaxine or desvenlafaxine (also used to treat depression).
• triptans (used for migraine).
• medicines for treating depression, e.g., tricyclic antidepressants, amphetamines, lithium, selective serotonin reuptake inhibitors (SSRIs), or serotonin and noradrenaline reuptake inhibitors (SNRIs).
• medicines that contain sibutramine (used for weight loss).
• medicines for pain, e.g., opioids such as tramadol, fentanyl, and its analogs, tapentadol, meperidine, methadone (also used for treatment of narcotic withdrawal and opioid dependence), and pentazocine.
• medicines that contain dextromethorphan (used for cough).
• products that contain St. John's Wort (also known as "Hypericum perforatum", a natural or herbal remedy used to treat mild depression).
• products that contain tryptophan (used for problems such as sleep and depression).
• medicines that contain ketoconazole (an antifungal).
• Additionally, if you are being treated by other healthcare professionals, inform them that you are taking desvenlafaxine.

Serotonin syndrome or reactions similar to Neuroleptic Malignant Syndrome (NMS)

Rarely, a disorder called serotonin syndrome or reactions similar to NMS may occur, which can cause significant changes in brain, muscle, and digestive system function due to high levels of serotonin in the body. This potentially life-threatening condition may occur when taking medicines like desvenlafaxine, particularly when taken with other medicines mentioned above.

See the section "Warnings and precautions" or possible side effects related to serotonin syndrome or reactions similar to NMS.

Switching antidepressants

When switching treatment from another antidepressant to desvenlafaxine, withdrawal symptoms from the initial antidepressant have occurred. Your doctor may gradually reduce the dose of your initial antidepressant medication to help minimize these symptoms.

Interactions with laboratory tests

False positives for some substances such as phencyclidine (PCP) and amphetamines may occur in urine analysis of patients taking or having taken desvenlafaxine, even several days after treatment discontinuation.

Taking Desvenlafaxine Stada with food, drinks, and alcohol

Desvenlafaxine tablets can be taken with or without food.

You should avoid taking alcohol while using desvenlafaxine.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, or think you may be pregnant, or are planning to have a baby, ask your doctor for advice before taking this medicine.

If you take desvenlafaxine in the late stage of pregnancy, there may be an increased risk of heavy vaginal bleeding shortly after delivery, especially if you have a history of bleeding disorders. Your doctor or midwife should know that you are taking desvenlafaxine to advise you. When similar medicines (SSRIs) are taken during pregnancy, there may be an increased risk of a serious effect on the baby called persistent pulmonary hypertension of the newborn (PPHN), causing the baby to breathe faster and turn blue. These symptoms usually start during the first 24 hours after the baby is born. If your baby has these symptoms, you should contact your doctor and/or midwife immediately.

Tell your doctor before stopping treatment with desvenlafaxine during pregnancy, as you may experience a relapse of depression.

If you take desvenlafaxine during the middle to late stage of pregnancy, there may be an increased risk of high blood pressure and protein in the urine (preeclampsia). There may also be an increased risk of bleeding after delivery (postpartum hemorrhage).

If you take desvenlafaxine during pregnancy, inform your doctor and/or midwife, as your baby may experience withdrawal symptoms when born. These symptoms may appear soon after birth and may require hospitalization. The symptoms include difficulty feeding or breathing problems. If your baby has these or other symptoms when born and you are concerned, contact your doctor and/or midwife.

Desvenlafaxine passes into breast milk. There is a risk of an effect on the baby. Therefore, do not use desvenlafaxine during breastfeeding unless your doctor specifically advises you to.

Driving and using machines

Desvenlafaxine may cause dizziness, drowsiness, and blurred vision. Do not drive or operate tools or machines until you know how this medicine affects you.

Desvenlafaxine Stada 100 mg contains orange yellow S (E110).

This medicine may cause allergic reactions because it contains orange yellow S (E110). It may cause asthma, especially in patients allergic to acetylsalicylic acid.

3. How to take Desvenlafaxine Stada

Follow exactly the instructions of your doctor. If you are unsure, ask your doctor again.

The recommended dose is 50 mg once a day. Your doctor may increase your dose to 100 mg once a day or even up to a maximum of 200 mg once a day if necessary.

If you have kidney problems or a history of kidney problems, consult your doctor, as you may need to take a different dose of desvenlafaxine.

Desvenlafaxine should be taken orally, approximately at the same time each day. The tablets should be swallowed whole with liquid, without dividing, crushing, chewing, or dissolving them.

Do not worry if you see the tablet structure in your stool after taking desvenlafaxine.As the tablet travels through your gastrointestinal tract, the active substance desvenlafaxine is slowly released. The tablet structure does not dissolve and is eliminated in the stool. Therefore, even if you see the tablet structure in your stool, you will have absorbed your dose of desvenlafaxine.

If you take more Desvenlafaxine Stada than you should

Contact your doctor or pharmacist immediately if you take more desvenlafaxine than your doctor prescribed.

In case of overdose or accidental ingestion, consult your doctor, pharmacist, or call the Toxicology Information Service. Phone 91 562 04 20, indicating the medicine and the amount taken. It is recommended to take the packaging and the leaflet of the medicine to the healthcare professional.

If you forget to take Desvenlafaxine Stada

If you miss a dose, take it as soon as you remember. However, if it is already time for your next dose, skip the missed dose and take only one dose, as usual. Do not take a double dose to make up for the missed dose.

If you stop taking Desvenlafaxine Stada

Do not stop taking desvenlafaxine or change your dose without talking to your doctor first, even if you feel better. Your doctor will prefer to gradually reduce the dose of desvenlafaxine to avoid side effects. It is known that patients experience side effects when they stop taking desvenlafaxine, especially if they have taken a high dose and for a prolonged period. Some of these side effects are: dizziness, nausea, headache, fatigue, irritability, diarrhea, anxiety, nightmares, and excessive sweating. Therefore, the dose should be reduced slowly, and under medical supervision, in case you and your doctor decide to stop treatment with desvenlafaxine. If you experience any of these or other symptoms that bother you, consult your doctor (see section "Warnings and precautions"). In some patients, complete discontinuation of the medicine may require months or even longer.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
