5. Storage of Metalgial


Metamizole, the principal ingredient of Metalgial 500mg/ml oral drops in solution, is a analgesic and antipyretic medicine for the treatment of pain and fever. It belongs to the pyrazalone group of medicines.


Metalgial 500mg/ml oral drops in solution is used in the treatment of acute post operation or post trauma pain, colic pain or pain originating from a tumour. It is also used in cases of high temperatures which do not respond to other antithermics.


Do not take Metalgial:

-    If your doctor has not prescribed this medicine.

-    If you have a history of hyper sensibility (allergy) to metamizole or any other pyrazolonic derivatives or any of the other components of this medicine.

-    If you have reacted with a decrease in the number of white blood cells (agranulocytosis) after using these substances.

-    If you have had symptoms of asthma, rhinitis or hives (red rashes or wheals on the skin which can itch) after the administration of asperin, paracetomol or anti inflammatories, not steroids, as you may be predisposed to be sensible to metamizole (crossed sensibility).

-     If your doctor has diagnosed you with intermittent acute porphyria (a disorder of the blood pigments metabolism which form part of the haemoglobin).

-    If your doctor has diagnosed a congenital deficiency of dehydrogenated glucose-6-phosphate (a lack of a protein present in the red blood cells which can cause a type of anaemia known as hemolytic anaemia).

-    If you have suffered alterations of the functioning of bone marrow, for example after receiving chemotherapy, or if you have had blood illnesses.


Be especially careful with Metalgial

-    If you present dizziness, breathing difficulty, rhinitis, facial swelling (angyneurotic edema), decrease in blood pressure, the sudden apparition of red stains on the skin, you must suspend the treatment and consult your doctor immediately, as it could be the sign of a serious allergic reaction (anaphylaxis/anaphylactic shock).

-    If during the treatment you have a high temperature, shivers, sore throat inflammation in the mouth, nose or throat, injuries in the oral or genital mucosa you must suspend the treatment and consult your doctor immediately as this could indicate a decrease in the number of white blood cells (agranulocytosis).

-    If you have had an allergic reaction to metamizole, you must not take medicine with it again.

-    If you suffer asthma syndrome due to painkillers, bronquial asthma, especially with rinosinusitis and nasal polyps, chronic hives, or if you are intolerant to colouring agents and/or preservatives or alcohol, as the risk of possible serious allergic reactions is greater.

-    If you have pre existing problems of low blood pressure (below 100mmHg) or have unstable circulation or present a high temperature as the risk of a sharp drop in blood pressure is greater.

-    If you have a diminished hepatic or renal function.


Use of other medicines

Inform your doctor or pharmacist if you are using or have recently used other medicines including those acquired without prescription.


If you administer metamizole in conjunction with cyclosporine, you can reduce the levels of cyclosporine in the blood, as such these need to be measured regularly.


Taking Metalgial with food and drink:

Combined with alcohol the effects of both substances may be increased.


Pregnancy and while breast feeding:

Consult your doctor or chemist before taking any medicine.


It is recommended not to administer the medicine during the first and last trimester of pregnancy. In the second trimester it shall only be used once the doctor has weighed up the benefit/risk balance.


The metalobites of metamizole are excreted with maternal milk, as such breast feeding must be avoided for the 48 hours following its administration.


Driving and the use of machines:

Although adverse effects on the capacity to concentrate and react are not expected, with higher doses, among those recommended, it should be born in mind that these capacities could be affected and the use of machines, driving and other dangerous activities should be avoided. This is particularly true when alcohol has been consumed.


Important information about some of the components of Metalgial:

Patients with low sodium diets must bear in mind that this medicine contains 35 mg (1.5 mmol) of sodium per ml (20 drops).

-Drug induced rashes

-Decrease in blood pressure


Rare side effects, which affect between 1 and 10 of every 10000 patients.


-The weakest allergic reactions habitually manifest themselves as skin and mucosa symptoms (for example, itching, burning, reddening, hives, swelling), breathing difficulty, and with less frequency gastrointestinal disturbances. These weak reactions can progress till they are serious. In patients with asthmatic symptoms caused by painkillers, these reactions of intolerance habitually manifest themselves as asthma attacks.

-Skin rashes

-Decrease in the number of white blood cells (leucopoenia).


Very rare side effects, which affect less than 1 every 10000 people.


-Serious allergic reactions which can appear with generalised hives, swelling of feet, hands, lips, throat and respiratory paths (angyoedema), decrease in the passing of air to the lungs due to the sharp closure of the bronchi, alterations of the cardiac rhythm, decreased blood pressure (sometimes preceded by an increase in blood pressure) and circulatory crash, which can put your life at risk. These reactions can appear even if you have already taken metamizole on other occasions without complications and usually appear in the first hour following administration.

-Very serious cutaneous blistering reactions (Stevens-Johnson syndrome or Lyell’s syndrome).

-Decrease in the number of platelets in the blood (thrombocytopenia).

-Serious decrease in the number of white blood cells (agranulocytosis).
