Warnings and precautions

Consult your doctor or pharmacist before starting to take Quentiax if:

• You, or a family member, have or have had any heart problems, for example, irregular heart rhythm, heart muscle weakness, or heart inflammation, or if you are taking any medication that may affect your heart rate.
• You have low blood pressure.
• You have had a stroke, especially if you are an older adult.
• You have liver problems.
• You have had a seizure (convulsion).
• You have diabetes or are at risk of developing diabetes. Your doctor may monitor your blood sugar levels while taking Quentiax.
• You know you have had low white blood cell counts (which may or may not have been caused by other medications).
• You are an older adult with dementia (loss of brain function). If so, do not take Quentiax because the group of medications to which Quentiax belongs may increase the risk of stroke or, in some cases, death in these individuals.
• You are an older adult with Parkinson's disease or parkinsonism.
• You or a family member has a history of blood clots, as medications like these have been associated with blood clot formation.
• You have or have had a condition in which your breathing is interrupted by brief periods of time during normal nighttime sleep (called "sleep apnea") and are taking medications that decrease normal brain activity ("depressants").
• You have or have had a condition in which you cannot completely empty your bladder (urinary retention), have an enlarged prostate, intestinal obstruction, or high pressure inside your eye. These conditions may be caused by medications (called "anticholinergics") that affect how nerve cells function, to treat certain medical conditions.
• You have a history of alcohol or drug abuse.

Inform your doctor immediately if after taking Quentiax you experience any of the following:

• A combination of fever, intense muscle stiffness, sweating, or a decrease in consciousness (a condition called "neuroleptic malignant syndrome"). You may need immediate medical treatment. Uncontrolled movements, mainly of your face or tongue.
• Dizziness or feel very drowsy. This may increase the risk of accidental injuries (falls) in older adults. Seizures (convulsions).
• A long-lasting and painful erection (priapism).
• Fast and irregular heartbeats, even when at rest, palpitations, respiratory problems, chest pain, or unexplained fatigue. Your doctor should examine your heart and, if necessary, refer you to a cardiologist immediately.

These conditions may be caused by this type of medication.

Inform your doctor as soon as possible if you have:

• Fever, flu-like symptoms, sore throat, or any other infection, as this could be the result of low white blood cell counts, which may require discontinuing treatment with quetiapine and/or the treatment to be given.
• Constipation with persistent abdominal pain, or constipation that has not responded to treatment, as this could lead to a more severe intestinal blockage.

Thoughts of suicide and worsening of depression

If you are depressed, you may sometimes think about harming yourself or committing suicide. This may increase at the beginning of treatment, as all these medications take time to take effect, usually around two weeks but sometimes longer. These thoughts may also increase if you stop taking your medication abruptly. You may be more likely to think this way if you are a young adult. Information obtained from clinical trials has shown an increased risk of thoughts of suicide and/or suicidal behavior in young adults under 25 with depression.

If you ever think about harming yourself or committing suicide, contact your doctor or go to the hospital immediately. It may help to tell a close family member or friend that you are depressed, and ask them to read this leaflet. You can ask them to tell you if they think your depression is getting worse, or if they are concerned about changes in your behavior.

Severe cutaneous adverse reaction (SCAR)

Severe cutaneous adverse reactions (SCARs), which may put your life at risk or be fatal, have been reported very rarely with quetiapine treatment. These have manifested frequently by:

• Stevens-Johnson syndrome (SSJ), a widespread rash with blisters and skin peeling, especially around the mouth, nose, eyes, and genitals.
• Toxic epidermal necrolysis (TEN), a more severe condition that causes extensive skin peeling.
• Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), consisting of flu-like symptoms with a rash, fever, swollen lymph nodes, and abnormal blood test results (including an increase in white blood cells (eosinophilia) and liver enzymes).
• Acute generalized pustular psoriasis (AGPP), small pus-filled blisters.
• Erythema multiforme (EM), a skin rash with irregular red patches that itch.
