1. What is Fenactil and what is it used for

Fenactil belongs to a group of medicines called neuroleptics. It contains the active substance chlorpromazine hydrochloride. The medicine has antipsychotic and antiemetic effects, and to a lesser extent, hypotensive (blood pressure lowering) and sedative effects. It is available in the form of oral drops for exclusive oral use.

Indications:

• Psychiatric disorders, such as: schizophrenia and other types of psychosis (especially paranoid), manic states, hypomanic states;
• As an adjunct in the short-term treatment of anxiety states, psychomotor agitation, violent or dangerous impulsive behavior;
• Childhood schizophrenia and autism;
• Nausea and vomiting, when other medicines are ineffective or unavailable;
• Intractable hiccups.

When not to take Fenactil

Warnings and precautions

Fenactil should be used with caution if:

• you are elderly (over 65 years old), especially if you are exposed to high or low temperatures, which can increase or decrease body temperature. In elderly patients, the medicine may cause orthostatic hypotension (dizziness or fainting when standing up from a sitting or lying position);
• you have epilepsy or are prone to seizures, as this medicine may increase the risk of a seizure.

If you develop a fever of unknown origin during treatment, you should contact your doctor immediately, as this may be a sign of a malignant neuroleptic syndrome (see section 4: Possible side effects).
Sudden discontinuation of treatment may cause symptoms of acute withdrawal syndrome (see section: Discontinuation of Fenactil treatment).
In patients with schizophrenia, the response to neuroleptic treatment may be delayed.
If the medicine is discontinued, the symptoms of the disease may reappear only after some time (after several weeks or months).
If you are at risk of arrhythmias (heart rhythm disorders), especially if you have: heart disease, electrolyte disturbances in the blood (decreased potassium, calcium, or magnesium levels in the blood), are malnourished, abuse alcohol, or are taking other medicines that prolong the QT interval, Fenactil should only be administered when the benefit outweighs the risk. In such a patient, the doctor should perform biochemical blood tests and ECG, especially at the beginning of treatment.
Fenactil should not be used as the only medicine if depression is the main symptom. This medicine may be used with antidepressants in cases where psychoses occur simultaneously.
During treatment, you should avoid exposure to sunlight and sunbathing (including in a solarium), as Fenactil may cause sensitivity to sunlight and UV radiation.
Fenactil applied to the skin may cause discoloration, so you should protect your skin from accidental contact with the solution.
The medicine may cause urine to turn pink to orange in color.

Fenactil and other medicines

Tell your doctor or pharmacist about all medicines you are taking, have recently taken, or plan to take.
Be especially careful when taking Fenactil with the following medicines:

• adrenaline(a medicine used, among other things, in resuscitation), should not be administered to a patient after an overdose of Fenactil;
• barbiturates(medicines used to treat insomnia and epilepsy) and sedatives, as they enhance the effect of Fenactil, which may lead to respiratory depression (slowing and shallowing of breathing, apnea, and death due to suffocation);
• anticholinergics(used to treat asthma or spastic conditions of the digestive tract), as they may weaken the antipsychotic effect of Fenactil and enhance its anticholinergic effect, leading to constipation, heat strokes, etc.;
• alkalizers(neutralizing excess stomach acid), as they may weaken the effect of Fenactil;
• lithium-containing medicines(used to treat depression), as they may weaken the effect of Fenactil;
• medicines used to treat Parkinson's disease(e.g., levodopa), as they may weaken the effect of Fenactil;
• medicines that lower blood pressure(e.g., alpha-adrenergic blockers, guanethidine, propranolol, clonidine), as Fenactil may enhance or weaken their effect, act antagonistically (opposite to the effect of another medicine); regular blood pressure monitoring is recommended;
• medicines used to treat diabetes, as high doses of Fenactil may reduce their effect; the doctor should adjust the dose of these medicines accordingly;
• amphetamines;
• phenobarbital(a medicine used to treat epilepsy), as Fenactil affects its blood levels;
• deferoxamine(a medicine used to treat iron overdose), as it may lead to brain function disorders (transient metabolic encephalopathy, characterized by loss of consciousness for 48-72 hours);
• medicines that prolong the QT interval(e.g., certain antiarrhythmic medicines, antidepressants, and other antipsychotic medicines), as there is an increased risk of arrhythmias (heart rhythm disorders);
• myelosuppressive medicines(acting toxic to the bone marrow, such as carbamazepine - a medicine used to treat epilepsy, and some antibiotics and anticancer medicines), as there is a risk of developing agranulocytosis (a decrease in the number of granulocytes - one of the types of white blood cells, making you more susceptible to infections).

If you are not sure if you are taking any of the above medicines, ask your doctor or pharmacist.

4. Possible side effects

Like all medicines, Fenactil can cause side effects, although not everybody gets them.

Symptoms requiring immediate contact with a doctor:

• allergic reactions(rare or very rare), such as:
• anaphylactic shock(the first symptoms may be: skin rash, facial swelling, swelling of the lips or throat, difficulty breathing, wheezing, shortness of breath, imperceptible pulse, significantly lowered blood pressure, sweating, loss of consciousness, cardiac arrest, and death);
• angioedema(sudden swelling of the face, limbs, or joints without itching or pain);
• bronchospasm(wheezing, shortness of breath);
• urticaria(pink, itchy blisters on the skin) and various skin rashes;
• systemic lupus erythematosus(a chronic disease caused by immune system disorders, affecting many organs, characterized by skin changes, such as a butterfly-shaped rash on the face);
• transient jaundice(very rare) characterized by yellowing of the skin and whites of the eyes. A warning sign may be the sudden onset of fever 1 to 3 weeks after starting treatment;
• malignant neuroleptic syndrome(whose symptoms are: pallor, hyperthermia - a state of elevated body temperature, autonomic nervous system disorders (sweating, unstable blood pressure may be the first warning signs), muscle stiffness, and impaired consciousness). Dehydration and organic brain diseases may predispose to the development of malignant neuroleptic syndrome.

Side effects occur rarely during Fenactil treatment. The most common ones are nervous system disorders:

• acute dystonias(persistent involuntary muscle contractions causing, for example, twisting or abnormal positioning of the limbs);
• dyskinesias(uncoordinated and involuntary movements of the limbs or the whole body), usually short-term, more common in children and adolescents during the first four days of treatment or after increasing the dose;
• late dyskinesiasthat may occur during long-term use of high doses of Fenactil, even after discontinuation of treatment. The smallest possible doses of the medicine should be used;
• akathisia(motor restlessness with a need for frequent changes in body position) usually occurs after administration of a high initial dose;
• parkinsonismmore common in adults and the elderly, usually after several weeks or months of treatment. The most common symptoms are: tremors, stiffness, akinesia (body movements become delayed and inefficient);
• insomnia;
• agitation.

Additionally, the following may occur:

• leukopenia(decrease in the number of leukocytes); rarely, agranulocytosis(decrease in the number of granulocytes - one of the types of white blood cells) may occur;
• hyperprolactinemia(elevated prolactin levels in the blood), which may manifest as galactorrhea (milk leakage from the breasts), gynecomastia (breast enlargement in men), amenorrhea (absence of menstruation), and impotence (erectile dysfunction);
• eye changes- in some patients, especially women treated with chlorpromazine for a long time (from four to eight years), changes in the eyes and metal-gray-violet discoloration of exposed skin have been observed;
• heart arrhythmias(heart rhythm disorders), including atrial arrhythmias, atrioventricular block, ventricular tachycardia, atrial fibrillation, likely dose-dependent. These symptoms may occur, especially if you have heart disease, are elderly (over 65 years old), have hypokalemia (elevated potassium levels in the blood), or are taking other medicines that prolong the QT interval. Minor changes in ECG (such as: QT interval prolongation, ST segment depression, changes in U and T waves) are observed;
• hypotension(low blood pressure), usually orthostatic hypotension(dizziness or fainting when standing up from a sitting or lying position). It occurs, especially in the elderly or with hypovolemia (decreased blood volume), more common after intramuscular administration of Fenactil;
• dryness of the mucous membranes of the mouth;
• respiratory depression(slowing and shallowing of breathing, apnea, and death due to suffocation);
• decreased nasal patency(feeling of nasal congestion);
• increased skin sensitivity to sunlight and UV radiation, especially in patients taking high doses of the medicine (see section: Warnings and precautions);
• contact allergy- may occur rarely, in case of frequent skin contact with the medicine;
• priapism(painful erection), if it occurs, you should contact your doctor, as you may need treatment.
