• If you have epilepsy. Treatment should be interrupted if seizures occur.
• If you have severe heart and/or circulatory problems.

• If you have any liver or kidney problems.
• If you have a history of liver disease.
• If you have intestinal obstruction (paralytic ileus).
• Ensure the absence of some factors that favor the development of cardiac rhythm alterations (ventricular arrhythmia): bradycardia <55
• If your treatment is prolonged, your doctor may recommend an eye examination and blood test.

• In case of fever, sore throat, infection, or appearance of ulcers in the mouth, your doctor will perform a blood test to rule out a possible decrease in a type of white blood cell, granulocytes, or an increase in the number of leukocytes.
• If you suffer from seizures. It may increase the risk of their occurrence, so your doctor will subject you to special control, performing an electroencephalogram.
• This type of medication may potentiate the development of cardiac rhythm alterations (prolongation of the QT interval) that can be severe (torsades de pointes) and cause death. Therefore, your doctor will perform the necessary controls to exclude possible risk factors before starting treatment and if necessary during it.
• Older patients have a higher probability of experiencing sedation and decreased blood pressure (orthostatic hypotension).
• In older patients with dementia-related psychosis and being treated with antipsychotics (possibility of presenting a higher risk of death).
• If you have risk factors for suffering thromboembolism (formation of blood clots) (see section “4. Possible adverse effects”).

• If you or your caregiver:

• note a yellowish discoloration of the skin or eyes (jaundice) and the urine becomes darker. These may be signs of liver damage.
• suspect any allergic reaction while taking chlorpromazine.

You must immediately inform a doctor if you experience symptoms such as fatigue (asthenia), anorexia, nausea, vomiting, abdominal pain, due to the severe toxicity of this medication to the liver, which can be sometimes fatal. Your doctor should immediately initiate investigations including clinical examination and biological evaluation of liver function (see section “4. Possible adverse effects”).

• If you have diabetes mellitus or risk factors for developing it, as you must control your blood glucose levels (blood sugar levels) properly while taking Largactil.
• If you are being treated with lithium, other medications that may prolong the QT interval, dopamine agonist antiparkinsonian medications (see section “Taking Largactil with other medications”).

If you develop a severe rash or other skin symptoms, stop taking chlorpromazine and contact your doctor or seek medical attention immediately.

Taking Largactil with other medications

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication.

-Medications for treating Parkinson's disease such as amantadine, bromocriptine, cabergolina, levodopa, lisurida, pergolida, piribedil, ropinirol.

• Levodopa (medication for treating Parkinson's disease): if movement disorders occur, your doctor will not prescribe or replace levodopa with another medication.

- Medications that may prolong the QT interval (heart disorder): there is an increased risk of arrhythmias when chlorpromazine is used simultaneously with medications that prolong the QT interval (including some antiarrhythmics and other antipsychotics including sultoprida) and medications that may cause electrolyte imbalance.

-Alcohol: alcohol consumption potentiates the sedative effect of Largactil.

-Guanetidina (medication for treating hypertension): concurrent administration with guanetidina reduces the antihypertensive effect of this.

- Sultoprida (medication for treating psychosis): administering Largactil together with sultoprida may cause cardiac rhythm alterations that can be severe (torsade de pointes).

- Litio (medication for treating bipolar disorder): concurrent administration of lithium and chlorpromazine may cause confusional syndrome, increased muscle tone, and increased reflexes.

Combinations requiring caution

-Medications for treating diabetes:la administration of high doses of chlorpromazine (100 mg/day) together with antidiabetic medications may increase blood glucose levels.You may need to adjust the dose of the antidiabetic medication.

• Concurrent administration with antacids (salts, oxides, and hydroxides of aluminum, magnesium, and calcium) reduces the absorption of Largactil. Therefore, it is recommended to take them at least two hours apart.

• Administration of Largactil with CYP1A2 inhibitors increases chlorpromazine concentrations.

• There may be an interaction between CYP2D6 inhibitors, such as phenothiazines (including chlorpromazine), and CYP2D6 substrates. Concurrent administration of Largactil with amitriptyline/amitriptylinoxide may increase plasma levels of amitriptyline/amitriptylinoxide. Monitor for possible adverse reactions associated with amitriptyline/amitriptylinoxide treatment.

Combinations to be considered

-Administration of Largactil with medications used to lower blood pressure (antihypertensives) increases their effect and the risk of decreased blood pressure upon initiation, which may cause dizziness.

-Medications for treating depression (type imipramina), medications for treating allergies that act on the brain, tranquilizers, medications for treating Parkinson's disease, for treating spasms, and disopiramida, when administered together with Largactil, increase the occurrence of the following adverse reactions: urinary retention, constipation, and dry mouth.
