Nozinan Injection belongs to a group of medicines called phenothiazines. It is used for the relief of severe pain and as a sedative to relieve anxiety and distress associated with severe pain, particularly in terminally ill patients.

This medicine is given by a healthcare professional either by injection into a muscle or vein, or slowly via a needle under the skin.


Do not use Nozinan Injection if:

  • You are allergic (hypersensitivity) to levomepromazine hydrochloride or any of the other ingredients of Nozinan Injection (listed in section 6 below).
    Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue.
  • If you are taking any of the following medicines:
    • citalopram and escitalopram
    • hydroxyzine
    • piperaquine
    • domperidone

Warnings and precautions

Talk to your doctor or nurse before Nozinan Injection is given if:

  • You have liver or kidney problems
  • You are an elderly patient with dementia
  • You are elderly, frail, have heart disease or you have had problems with dizziness or feeling faint when going from a lying or sitting to a standing position due to low blood pressure, as you may feel faint or light-headed when you are given the injection. If you receive a large initial dose, you will have to stay in bed. You should not get up quickly and you should obtain assistance when necessary.
  • You suffer from slow or irregular heartbeats/palpitations (torsades de pointes) or have a family history of heart problems
  • You or someone else in your family have a history of blood clots, as medicines like these (antipsychotics) have been associated with formation of blood clots
  • You have been told by your doctor that you might have a stroke or you have risk factors (e.g. if you smoke or have high blood pressure, or have an excessive amount of sugar, cholesterol or fat in the blood). This medicine should be used with caution as the risk of a stroke (cerebrovascular accident) may be increased.
  • You are diabetic or have been told that you have an increased risk of diabetes. You will need to monitor your blood sugar levels very carefully.
  • You already know you have low levels of potassium, calcium or magnesium in your blood
  • You have constipation
  • You find it difficult, or are unable, to eat
  • You are an alcoholic
  • You have ever had convulsions or epilepsy
  • Your prostate (sperm-producing gland) has increased in size (prostate hypertrophy)
  • You have an adrenal gland tumour (phaeochromocytoma)
  • You have decreased thyroid hormone secretion condition (hypothyroidism)
  • You have a muscle disease causing drooping eyelids, double vision, difficulty in speaking and swallowing and sometimes muscle weakness in the arms or legs (myasthenia gravis)

During the treatment

You must tell your doctor or nurse immediately if:

  • You experience stiffness in your muscles, impaired consciousness and fever (see section 4).
  • You have a fever, pallor, heavy sweating or any other sign of infection. In very rare cases, this medicine can cause a drop in your white blood cells which predisposes you to infection (see section 4).
  • You have long-term constipation, as well as bloating and stomach pain, or a blocked intestine (Paralytic ileus) (see section 4).


Additional tests will be done by your doctor before and during treatment. This includes if you are being given Nozinan Injection for a long period of time, or if you are taking other medicines at the same time such as heart drugs, anti-depressants or drugs for mental health disorders. Your doctor may carry out:

  • blood tests to monitor your liver function.
  • blood tests to check your white blood cells due to a potential side effect, a significant decrease in the number of certain white blood cells in the blood (agranulocytosis).
  • an ECG (electrocardiogram) to check your heart is working normally, as certain medicines in the same family as NOZINAN (antipsychotics) can, in very rare cases, cause heart rhythm disorders (see section 4).
