What Yentreve is and what it is used for

Yentreve increases the levels of serotonin and noradrenaline in the nervous system.

Yentreve is a medicine to be taken by mouth to treat Stress Urinary Incontinence (SUI) in women.

Stress urinary incontinence is a medical condition in which patients have accidental loss or leakage of urine during physical exertion or activities such as laughing, coughing, sneezing, lifting, or exercise.

Yentreve is believed to work by increasing the strength of the muscle that holds back urine when you laugh, sneeze, or perform physical activities.

The efficacy of Yentreve is reinforced when combined with a training program called Pelvic Floor Muscle Training (PFMT).

Before you take Yentreve

DO NOT take Yentreve if you:

  • are allergic (hypersensitive) to duloxetine or any of the inactive ingredients of Yentreve
  • have liver disease
  • have severe kidney disease
  • are taking or have taken within the last 14 days, another medicine known as a monoamine
  • oxidase inhibitor – MAOI (see section below ‘Taking other medicines’)
  • are taking fluvoxamine which is usually used to treat depression, ciprofloxacin or enoxacine

which are used to treat some infections. Talk to your doctor if you have high blood pressure or heart disease. Your doctor will tell you if you should be taking Yentreve.

Take special care with Yentreve

The following are reasons why Yentreve may not be suitable for you. Talk to your doctor before you take the medicine if you:

  • are taking medicines to treat depression (see ‘Tacking other medicines’)
  • are taking St. John’s Wort, a herbal treatment (Hypericum perforatum)
  • have kidney disease
  • have a history of seizures (fits)
  • have had mania
  • suffer from bipolar disorder
  • have eye problems such as certain kinds of glaucoma (increased pressure in the eye)
  • have a history of bleeding disorders (tendency to develop bruises)
  • are at risk of low sodium levels
  • are younger than 18 years
  • are currently being treated with another medicine which may cause liver damage.
  • are taking other medicines containing duloxetine

Yentreve may cause a sensation of restlessness or an inability to sit or stand still. You should tell your doctor if this happens to you.

Thoughts of suicide and worsening of depression or anxiety disorder.

Although Yentreve is not indicated for the treatment of depression, its active ingredient (duloxetine) also exists as an antidepressant medicine. If you are depressed and/or have anxiety disorders you can sometimes have thoughts of harming or killing yourself. These may be increased when first starting antidepressants, since these medicines all take time to work, usually about two weeks but sometimes longer. You may be more likely to think like this if you:

  • have previously had thoughts about killing or harming yourself.
  • are a young adult. Information from clinical trials has shown an increased risk of suicidal
  • behaviour 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 a 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 post. 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 behaviour.

Use in children and adolescents under 18 years of age

Yentreve should not be used for children and adolescents under the age of 18 years. Also, you should know that patients under 18 have an increased risk of side-effects such as suicide attempt, suicidal thoughts and hostility (predominantly aggression, oppositional behaviour and anger) when they take this class of medicines. Also, the long-term safety effects concerning growth, maturation, and cognitive and behavioural development of Yentreve in this age group have not yet been demonstrated.


Taking other medicines

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. The main ingredient of Yentreve, duloxetine, is used in other medicines for other conditions: diabetic neuropathic pain, depression, anxiety and urinary incontinence

Using more than one of these medicines at the same time should be avoided. Check with your doctor if you are already taking other medicines containing duloxetine.

Your doctor should decide whether you can take Yentreve with other medicines. Do not start or stop taking any medicines, including those bought without a prescription and herbal remedies, before checking with your doctor.

You should also tell your doctor if you are taking any of the following:

  • Monoamine Oxidase Inhibitors (MAOI): you should not take Yentreve if you are taking or have recently taken within the last 14 days another antidepressant medicine called a monoamine oxidase inhibitor (MAOI). Taking an MAOI together with many prescription medicines, including Yentreve, can cause serious or even life-threatening side effects. You must wait at least 14 days after you have stopped taking an MAOI before you can take Yentreve. Also, you need to wait at least 5 days after you stop taking Yentreve before you take an MAOI.
  • Medicines that cause sleepiness: These include medicines prescribed by your doctor including alcohol and sedative medicines (benzodiazepines, strong painkillers, antipsychotics, phenobarbital, sedative antihistamines).
  • Medicines that increase the level ofserotonin. triptans, tramadol, tryptophan, SSRIs (such as paroxetine and fluoxetine), tricyclics (such as clomipramine, amitriptyline)and venlafaxine. These medicines increase the risk of side effects; if you get any unusual symptom taking any of these medicines together with Yentreve, you should see your doctor.
  • Oral anticoagulants: medicines which thin the blood. These medicines might increase the risk of bleeding.

Taking Yentreve with food and drink

Yentreve may be taken with or without food. You should take extra care if you drink alcohol while taking Yentreve.

Pregnancy and breast-feeding

Ask your doctor or pharmacist for advice before taking any medicine.

Tell your doctor if you become pregnant, or you are trying to become pregnant, while you are taking Yentreve. You should use Yentreve only after discussing the potential benefits and any potential risks to your unborn child with your doctor.

Make sure your midwife and/or doctor knows you are on Yentreve. When taken during pregnacy, similar drugs (SSRIs) may increase the risk of a serious condition in babies, called persistent pulmonary hypertension of the newborn (PPHN), making the baby breathe faster and appear bluish. These symptoms usually begin 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 take Yentreve near the end of your pregnancy, your baby might have some symptoms when it is born. These usually begin at birth or within a few days of your baby being born. These symptoms may include floppy muscles, trembling, jitteriness, not feeding properly, trouble with breathing and fits. If your baby has any of these symptoms when it is born, or you are concerned about your baby’s health, contact your doctor or midwife who will be able to advise you.

Tell your doctor if you are breast-feeding. The use of Yentreve while breastfeeding is not recommended. You should ask your doctor or pharmacist for advice.

If you stop taking Yentreve
