Nolotil 5 ml (Metamizole): Uses, Benefits, Safety Information, and Important Considerations
Nolotil 5 ml: Educational Guide
Nolotil 5 ml is an injectable formulation containing metamizole (also known as dipyrone), a medication used in some countries for the treatment of moderate to severe pain and high fever when other treatment options may not be suitable or effective. Metamizole belongs to a group of medicines known for their pain-relieving, fever-reducing, and antispasmodic properties.
The availability of metamizole varies worldwide. While it is prescribed in many countries throughout Europe, Latin America, and other regions, it is not approved for use in some countries because of concerns about rare but serious side effects. Patients should always use this medicine only under the guidance of a qualified healthcare professional.
What Is Nolotil 5 ml?

Nolotil 5 ml is an injectable medicine that contains metamizole sodium. Healthcare professionals may administer it by intravenous or intramuscular injection depending on the patient’s condition and clinical judgment.
It is commonly prescribed in hospital or clinical settings when rapid pain or fever control is required.
Medical Uses
Healthcare professionals may prescribe Nolotil 5 ml for several medical conditions, including:
- Moderate to severe acute pain
- Pain after surgery
- Severe headache or migraine in selected cases
- Kidney stone pain (renal colic)
- Biliary colic
- Cancer-related pain when appropriate
- High fever that has not responded adequately to other medications
The exact treatment approach depends on the patient’s age, medical history, and overall health.
How Does Metamizole Work?
Metamizole helps relieve pain by reducing the production of substances involved in pain and inflammation. It also lowers elevated body temperature and has antispasmodic effects, making it useful for painful muscle spasms involving the digestive or urinary tract.
Unlike opioid pain medicines, metamizole does not produce opioid-related effects such as respiratory depression.
Administration
Nolotil 5 ml is intended to be administered by trained healthcare professionals. The route of administration, dosage, and frequency depend on factors such as:
- Age
- Body weight
- Severity of symptoms
- Kidney function
- Liver function
- Overall medical condition
Patients should never inject prescription medications unless specifically instructed and trained by a healthcare provider.
Possible Benefits
When prescribed appropriately, Nolotil may offer:
- Rapid pain relief
- Effective fever reduction
- Relief of certain types of muscle spasms
- Alternative pain management when other medicines are unsuitable
- Use in hospital and emergency care settings
Treatment decisions should always balance potential benefits with possible risks.
Possible Side Effects
Like all medicines, Nolotil may cause side effects. Many people tolerate it well, but adverse reactions can occur.
Common side effects may include:
- Low blood pressure
- Nausea
- Dizziness
- Skin rash
- Injection-site discomfort
Less common but potentially serious reactions include:
- Severe allergic reactions
- Changes in blood cell counts
- Serious skin reactions
- Liver problems
A rare but serious adverse effect associated with metamizole is agranulocytosis, a condition involving a marked reduction in certain white blood cells that can increase the risk of severe infections. Because of this risk, patients should seek prompt medical attention if they develop symptoms such as fever, sore throat, or signs of infection while taking metamizole.
Precautions
Patients should inform their healthcare provider before receiving Nolotil if they have:
- Previous allergy to metamizole or similar medicines
- Blood disorders
- Bone marrow disorders
- Liver disease
- Kidney disease
- Asthma associated with pain medications
- Low blood pressure
- Pregnancy or breastfeeding
Healthcare professionals can determine whether Nolotil is appropriate based on an individual’s medical history.
Drug Interactions
Metamizole may interact with certain medications. Patients should tell their healthcare provider about all prescription medicines, over-the-counter medicines, vitamins, and herbal supplements they use.
Potential interactions may involve:
- Blood-thinning medications
- Certain immunosuppressive medicines
- Some blood pressure medicines
- Other pain medications
Only a healthcare professional can evaluate the significance of possible interactions.
Storage
Storage recommendations depend on the manufacturer’s instructions and local regulations. Medicines should generally be kept in their original packaging and stored out of the reach of children.
Healthcare facilities should follow proper handling and storage procedures for injectable medications.
