6. Contents of the pack and additional information

Desvenlafaxina Neuraxpharm contains the active substance desvenlafaxine (as benzoate).

This medicine is an antidepressant that belongs to a group of medicines called serotonin and noradrenaline reuptake inhibitors (SNRIs).This group of medicines is used to treat depression.

The exact way in which antidepressants work is not fully understood, but they may help increase the levels of serotonin and noradrenaline in the brain.

Desvenlafaxina is a treatment for adults.

Do not take Desvenlafaxina Neuraxpharm:

• if you are allergic to desvenlafaxine, venlafaxine, or any of the other ingredients of this medication (listed in section 6).
• if you are also taking or have taken within the last 14 days, a medication known as a monoamine oxidase inhibitor (MAOI) used to treat depression, infections, or Parkinson's disease. Taking a MAOI (for example linezolid or methylene blue) with other medications such as Desvenlafaxina, may produce severe or potentially life-threatening side effects. Additionally, you should wait at least 7 days after stopping Desvenlafaxina before taking any MAOI (see also the sections “Serotonin syndrome” and “Other medications and Desvenlafaxina Neuraxpharm”).

Warnings and precautions

Consult your doctor if you have had any of the following conditions before taking Desvenlafaxina or if they occur during treatment with this medication:

• if you or a family member has a history of or has had mania (a state of overexcitement, feeling of euphoria, or irritability) or bipolar disorder (extreme mood swings, for example, 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 a heart attack.
• if you have a history of seizures (convulsions).
• if you have a history of bleeding disorders (tendency to develop bruises or bleed easily), or if you are pregnant (see section Pregnancy, breastfeeding, and fertility), or if you are using nonsteroidal anti-inflammatory drugs (NSAIDs), aspirin (acetylsalicylic acid), and other medications 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 (restlessness and anxiety), altered consciousness, confusion, coma, palpitations, increased blood pressure, elevated body temperature, excessive sweating, lack of coordination, muscle spasms or rigidity, tremors, nausea, vomiting, and diarrhea. Contact your doctor immediately, as you may be experiencing serotonin syndrome (a disorder that can be severe and, in rare cases, fatal).
• if you stop treatment abruptly, you may experience withdrawal symptoms (for example, mood changes, irritability, agitation, dizziness, anxiety, confusion, headache, sleep disturbances, tinnitus (ringing in the ears), and seizures). Therefore, it is essential to reduce the dose of Desvenlafaxina gradually and under medical supervision whenever you and your doctor decide to discontinue treatment.

Some medications in the group to which Desvenlafaxina belongs (called SSRIs/SNRIs) may cause sexual dysfunction side effects (see section 4). In some cases, these side effects persist after stopping treatment.

Desvenlafaxina may cause restlessness or an inability to sit or remain still during the first weeks of treatment.You should inform your doctor if this happens.

Thoughts of suicide and worsening of your depression

If you are depressed, you may have had thoughts of harming yourself or suicide.These thoughts may increase when you start taking antidepressants, as these medications take time to work, usually two weeks, but sometimes longer.

You may be more likely to have these thoughts:

• if you have had thoughts of suicide or self-harm before.
• if you are a young adult. Clinical trial information has shown an increased risk of suicidal behavior in young adults (less than 25 years old) with psychiatric disorders treated with antidepressants.

If you have thoughts of harming yourself or suicide at any time,contact your doctor or go to the hospital directly.

You may find it helpful to tell a close family member or friend who is depressed, and ask them to read this leaflet. You could also ask them to tell you if they think your depression or anxiety is getting worse, or if they are concerned about changes in your behavior.

Medications like desvenlafaxine (called SSRIs/SNRIs) may cause sexual dysfunction side effects (see section 4). In some cases, these side effects persist after stopping treatment.

Additionally, you should know that, in patients under 18 years old, there is a higher risk of adverse effects such as suicidal behavior, suicidal thoughts, and hostility (mainly aggression, confrontational behavior, and anger) when taking this type of medication.

Despite this, the doctor who prescribes this medication to you may prescribe it to patients under 18 years old when they decide it is the best option for the patient.

If the doctor who prescribes this medication to you has prescribed it to a patient under 18 years old and wants to discuss this decision, please return to your doctor.
