Warnings and precautions

• if your body temperature increases inexplicably, consult your doctor immediately, due to the risk of developing a syndrome called malignant neuroleptic syndrome, described during treatment with this type of medication, whose effects include pallor, increased body temperature, nervous system disorders, altered consciousness, and muscle rigidity. If you have sweating or your blood pressure becomes unstable, you may be developing symptoms indicating the onset of malignant neuroleptic syndrome. Although there are patients who may be predisposed to developing this syndrome with this type of medication, there are risk factors such as dehydration or brain damage.

• if you have risk factors for suffering a cerebral infarction.
• if you have severe heart and/or circulatory problems, as some heart medications (such as quinidine and its derivatives) can increase heartbeats or decrease blood pressure if you are taking Nemactil. If you have heart problems or your heart beats slower, your doctor will closely monitor you during treatment.
• if you have low potassium levels in your blood, your doctor will closely monitor you during treatment.

• if you have any liver or kidney disorders, your doctor will control the medication levels in your blood to prevent it from accumulating in your body.

• if your treatment is prolonged, your doctor may recommend an eye examination and a blood test.

• this type of medication may potentiate the development of cardiac rhythm disorders (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 treatment.
• Nemactil is not recommended for children under 3 years old. Oral solution can be used in children under 6 years old only in exceptional cases in specialized units. When administered to children of these ages, strict medical monitoring of adverse reactions, particularly neurological, is recommended.It is recommended to perform an annual clinical examination to evaluate the child's learning abilities, due to cognitive impact and the need to regularly adjust the dose based on the child's clinical condition.

In elderly patients, as they have a higher probability of experiencing drowsiness and dizziness when getting up due to decreased blood pressure.They may also experience extrapyramidal reactions, constipation (paralytic ileus), or

prostatic hypertrophy.

• you should avoid exposure to the sun.
• in elderly patients with dementia-related psychosis, who are being treated with antipsychotics (possibility of a higher risk of death).
• if you have risk factors for developing thromboembolism (blood clot formation) (see "Possible adverse effects").
• if you have diabetes mellitus or risk factors for developing it, as you should control your blood glucose levels (glucose levels in blood) when taking Nemactil.

Important information about some of the components of Nemactil

Alcohol

This medication contains 91.4 mg of alcohol (ethanol) in each ml, equivalent to 9.14% v/v. The amount in ml of this medication is equivalent to less than 2.26 ml of beer or 0.9 ml of wine.

The small amount of alcohol in this medication does not produce any perceptible effect.

Saccharose

This medication contains saccharose. If your doctor has told you that you have an intolerance to certain sugars, consult with them before taking this medication. It may cause tooth decay.

Other medications and Nemactil

Taking Nemactil with other medications, inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication.

Like other medications used to treat psychosis, if Nemactil is administered together with levodopa (medication used to treat Parkinson's disease), the effect of these medications may be cancelled out.If you have Parkinson's disease, your doctor will prescribe the lowest possible dose of both medications.In the case of movement disorders, your doctor will not prescribe levodopa, or will replace it with another medication.

During treatment, avoid alcoholic beverages and medications containing alcohol. The effect of alcohol potentiates sedation.

The concomitant administration of Nemactil with guanetidine (medication for hypertension treatment) produces a decrease in the effect of this medication.

The concomitant administration of Nemactil with antihypertensive medications increases the effect of these medications and the risk of decreased blood pressure when getting up, which may cause dizziness.

The concomitant administration of Nemactil with antacids (salts, oxides, and hydroxides of aluminum, magnesium, and calcium) produces a decrease in the absorption of Nemactil. Therefore, it is recommended to take them at least two hours apart.

Medications that act on the brain, such as tranquilizers, morphine derivatives (medications for pain and cough treatment), barbiturates, medications for allergy treatment, sleep inducers, antidepressants, medications for anxiety treatment, clonidine, and related substances (medications for hypertension, headache, or drug withdrawal), metadone, and talidomide, potentiate the effect of Nemactil. You should be cautious when driving or using machines.

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

If you are taking Lithium, the concomitant use of the two medications may increase the risk of developing cardiac rhythm disorders (prolongation of the QT interval) and symptoms suggesting an inexplicable increase in your body temperature (malignant neuroleptic syndrome) or lithium intoxication. Your doctor should closely monitor you if you take these two medications, especially at the beginning of treatment.

If you are taking medications for Parkinson's disease (amantadine, apomorphine, cabergoline, entacapone, lisuride, pergolide, piribedil, pramipexole, quinagolide, ropinirole), you should not take neurolépticos. If you are being treated for Parkinson's disease with a dopaminergic medication and need to be treated with a neuroléptico, you should interrupt the Parkinson's disease treatment, as the concomitant administration of these medications increases psychotic symptoms and cannot exert its effect.

You should inform your doctor if you are taking any of the following medications:

• Some medications used to treat arrhythmias: quinidine, procainamide, amiodarone, mibefradil.
• Some medications used to treat different types of infections: erythromycin, cotrimoxazole, trimethoprim-sulfamethoxazole, azithromycin, ketoconazole, pentamidine.
• Medications that act on gastrointestinal motility: cisaprida.
• Some medications used to treat allergies: terfenadine.
• Some medications for high cholesterol treatment: probucol.
• Some medications for psychosis treatment: haloperidol, sultopride, and other phenothiazines.
• Some medications for depression treatment: tricyclic and tetracyclic antidepressants.
• Other medications: organophosphates (for cancer treatment) and vasopressin (for severe blood pressure drops).

because it may increase the risk of developing cardiac rhythm disorders.

There is a possible interaction between CYP2D6 inhibitors, such as phenothiazines (including periciazine), and CYP2D6 substrates.The concomitant administration of Nemactil with amitriptyline/amitriptylinoxide may produce an increase in amitriptyline/amitriptylinoxide plasma concentrations. If you are being treated with these medications, your doctor will monitor you for adverse reactions.

Taking Nemactil with food and drinks

You should not take alcoholic beverages during Nemactil treatment, as the effect of alcohol potentiates sedation.

The bottle should be inverted to obtain the indicated dose.

When starting to take Nemactil, you should remain lying down for the hour following each dose. If your dose is high, it is essential to monitor your blood pressure due to the risk of it dropping upon rising.

Remember to take your medication.

Usual doses may vary depending on the indications and the patient's age. The daily dose will be divided into 2-3 doses:

- in patients with character and behavior disorders: the recommended dose for adults is 10 to 60 mg per day. The recommended dose for the elderly is 5 to 15 mg per day. The dose for children will be 1 mg per year of age (see "Be especially careful with Nemactil").
