WHAT IS IN THIS LEAFLET

All medicines have risks and benefits. Your doctor has weighed the risks of you taking Desvenlafaxine Actavis against the expected benefits it will have for you.

What Desvenlafaxine Actavis is used for

What it does

Desvenlafaxine is used in the treatment and prevention of relapse of depression. Depression can affect your whole body and may cause emotional and physical symptoms such as feeling low in spirit, being unable to enjoy life, poor appetite or overeating, disturbed sleep, loss of sex drive, lack of energy and feeling guilty over nothing.

Ask your doctor if you have any questions about why Desvenlafaxine Actavis has been prescribed for you. Your doctor may have prescribed it for another reason.

How it works

Desvenlafaxine Actavis contains the active ingredient called desvenlafaxine. It belongs to a class of medications called Serotonin-Noradrenaline Reuptake Inhibitors (SNRIs).

Serotonin and noradrenaline are chemical messengers that allow certain nerves in the brain to work. Desvenlafaxine Actavis tablets increase the level of these two messengers. Experts think this is how it helps to restore your feeling of wellness.

Desvenlafaxine Actavis is not addictive. It is available only with a doctor's prescription.

Before you take Desvenlafaxine Actavis

When you must not take it

Do not take Desvenlafaxine Actavis if you are taking other medications for depression known as monoamine oxidase inhibitors, even if you have stopped taking them, but have taken them within the last 14 days.

Do not take Desvenlafaxine Actavis if you are allergic to desvenlafaxine, venlafaxine or to any of the ingredients listed at the end of this leaflet.

Symptoms of an allergic reaction include:

  • Skin rash
  • Itching or hives on the skin
  • Swelling of the face, lips, tongue, throat or other parts of the body
  • Shortness of breath, wheezing, troubled breathing or difficulty swallowing.

Do not give Desvenlafaxine Actavis to children or adolescents under 18 years of age. The safety and effectiveness of desvenlafaxine in this age group have not been established.

Do not take this medicine after the expiry date (EXP) printed on the pack, or if the packaging is torn or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.

If you are not sure whether you should start taking this medicine, talk to your doctor.

Before you start to take it

Tell your doctor or pharmacist if you have allergies to any other medicines, foods, preservatives or dyes.

Tell your doctor or pharmacist if you are pregnant or intend to become pregnant. Desvenlafaxine Actavis is not recommended for use during pregnancy. Your doctor will discuss the risks and benefits of taking desvenlafaxine if you are pregnant. One of these risks is that newborn babies whose mothers have been taking desvenlafaxine may have several problems including breathing difficulties, seizures and lack of oxygen in their blood.

Tell your doctor or pharmacist if you are breast-feeding or plan to breast-feed. Desvenlafaxine passes into breast milk and there is a possibility that the breast-fed baby may be affected. For this reason, the use of desvenlafaxine is not recommended in breast-feeding women.

Tell your doctor if you have, or have had, any medical conditions, especially the following:

  • a history of fits (seizures or convulsions)
  • a personal history or family history of bipolar disorder
  • blood pressure problems
  • glaucoma (increased pressure in the eye)
  • a tendency to bleed more than normal or you are taking a blood thinning medication
  • raised cholesterol or lipid levels
  • problems with your kidneys or liver
  • problems with your heart
  • low sodium levels in your blood
  • any other medical conditions.

Tell your doctor if you plan to have surgery. If you have not told your doctor about any of the above, tell them before you start to take Desvenlafaxine Actavis.

Taking other medicines

Tell your doctor or pharmacist if you take any other medicines, including:

  • all prescription medicines
  • all medicines, vitamins, herbal supplements or natural therapies you buy without a prescription from a pharmacy, supermarket, naturopath or health food shop, such as St John's Wort or tryptophan supplements.

Do not start to take any other medicine while you are taking Desvenlafaxine Actavis, unless it is prescribed or approved by your doctor.

Some medicines may interfere with desvenlafaxine or desvenlafaxine may interfere with these medicines. These include:

  • medications for depression known as monoamine oxidase inhibitors (MAOIs) (such as moclobemide, phenelzine and tranylcypromine). Tell your doctor if you are taking or have stopped taking them within the last 14 days. Ask your doctor or pharmacist if you are unsure if you are taking any of these medicines. It is important that you do not take Desvenlafaxine Actavis or medicines similar to Desvenlafaxine Actavis with MAOIs or within 14 days of taking an MAOI as this may result in a serious life-threatening condition. Your doctor or pharmacist can tell you what to do if you are taking any of these medicines.
  • any other medications for bipolar disorder, depression, anxiety, obsessive-compulsive disorder or pre-menstrual dysphoric disorder, including St John's Wort
  • drugs that affect serotonin levels e.g. tramadol, dextromethorphan, fentanyl, methadone and pentazocine
  • medicines for weight loss, including sibutramine
  • triptans (used to treat migraine)
  • linezolid (used to treat infections)
  • drugs that affect your tendency to bleed e.g. aspirin, NSAIDS, warfarin.

You may need to take different amounts of your medicine, or you may need to take different medicines. Your doctor will advise you.

Your doctor or pharmacist has more information on medicines to be careful with or to avoid while taking Desvenlafaxine Actavis.

Switching to Desvenlafaxine Actavis from other antidepressants

Side effects from discontinuing antidepressant medication may occur if you are switched from other antidepressants, including venlafaxine, to Desvenlafaxine Actavis. Your doctor may gradually reduce the dose of your initial antidepressant medication to help reduce these side effects.

How to take Desvenlafaxine Actavis

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions on the box, ask your doctor or pharmacist for help.

How to take it

Swallow the tablets whole with a glass of water or other non-alcoholic liquid.

Do not divide, crush, chew or place the tablets in water.

Do not be concerned if you see a tablet 'shell' in your faeces after taking Desvenlafaxine Actavis. As the tablet travels the length of your gastrointestinal tract, the active ingredient desvenlafaxine is slowly released. The tablet 'shell' remains undissolved and is eliminated in your faeces. Therefore, even though, you may see a tablet 'shell' in your faeces, your dose of desvenlafaxine has been absorbed.

How much to take

The usual dose is 50 mg taken once daily with or without food.

Do not change your dose unless your doctor tells you to. Your doctor will gradually increase your dose if needed. If you have kidney problems, you may need a lower dose of Desvenlafaxine Actavis.

When to take it

Desvenlafaxine Actavis should be taken once daily and can be taken with or without food.

Take Desvenlafaxine Actavis at approximately the same time each day. This could be either in the morning or in the evening. Taking it at the same time each day will have the best effect. It will also help you remember when to take it.

How long to take it

Continue taking your medicine for as long as your doctor tells you. Although you may begin to feel better after two weeks, it may take several weeks before you feel much better. It is important to give Desvenlafaxine Actavis time to work.

This medicine helps to control your condition, so it is important to keep taking your medicine even if you feel well.

If you forget to take it

If it is less than 12 hours until your next dose, skip the dose you missed and then take your next dose when you are meant to. Otherwise, take it as soon as you remember, and then go back to taking as you would normally.

Do not take a double dose to make up for the dose you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist. If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (tel: 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital if you think that you or anyone else may have taken too much Desvenlafaxine Actavis.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Keep the telephone number for these places handy whilst taking any medications.

While you are taking Desvenlafaxine Actavis

Things you must do

Visit your doctor regularly for a check up so that your progress can be checked. Always discuss any questions you have about Desvenlafaxine Actavis with your doctor.

Take Desvenlafaxine Actavis tablets as your doctor has prescribed. Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine.

Keep enough Desvenlafaxine Actavis tablets to last weekends and holidays. This medicine helps to control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.

Watch carefully for signs that your depression is getting worse, especially in the first few weeks of treatment or if your dose has changed. Sometimes people with depression can experience a worsening of their depressive symptoms. This can happen even when taking an antidepressant.

Tell your doctor there is the potential for a false positive urinary drug screen while on Desvenlafaxine Actavis.

  • panic attacks
  • difficulty sleeping
  • irritability
  • aggressiveness
  • hostility or impulsiveness
  • restlessness
  • overactivity or uninhibited behaviour
  • other unusual changes in behaviour

Warning signs of suicide

If you or someone you know is showing the following warning signs, contact your doctor or a mental health advisor right away or go to the nearest hospital for treatment.

All thoughts or talk about suicide or violence are serious.

  • thoughts or talk about death or suicide
  • thoughts or talk about self-harm or doing harm to others
  • any recent attempts of self-harm

Things to be careful of

Things you must not do

Do not stop taking Desvenlafaxine Actavis or change the dose without the advice of your doctor, even if you feel better. Your doctor may want to slowly decrease your dose of Desvenlafaxine Actavis to help avoid side effects. Side effects are known to occur when people stop taking Desvenlafaxine Actavis, especially when they suddenly stop therapy.

Some of these side effects include:

  • headache
  • nausea
  • dizziness

Slowly reducing the amount of Desvenlafaxine Actavis being taken reduces the possibility of these effects occurring.
