2. Before using Metronidazol Serraclinics 5 mg/ml, solution for infusion EFG

Do not use METRONIDAZOL SERRACLINICS 5 mg/ml

  • If you are allergic to metronidazole, to medicines of the imidazole group, or to any of the other components of METRONIDAZOL SERRACLINICS 5 mg/ml

Be careful with METRONIDAZOL SERRACLINICS 5 mg/ml

  • if you have severe liver disorders.
  • if your treatment is prolonged. Your doctor may ask you to have regular blood tests, especially to check your white blood cell count. You will also be closely monitored for the risk of nervous system disorders such as paresthesia (tingling in feet or hands), ataxia (lack of coordination), dizziness, and convulsions.
  • if you have acute or chronic severe central or peripheral nervous system diseases, due to the possible risk of worsening.
  • if you have severe kidney disorders. In this case, your doctor may reduce the dose when you are not undergoing dialysis or when your blood levels of this medicine are not controlled.
  • it may darken the color of your urine.

There have been reports of severe liver toxicity/liver failure, some of which were fatal, in patients with Cockayne syndrome taking metronidazole-containing medications.

If you have Cockayne syndrome, your doctor should closely monitor your liver function while you are being treated with metronidazole and afterwards.

Tell your doctor immediately and stop taking metronidazole if you experience: stomach pain, loss of appetite, nausea, vomiting, fever, general malaise, fatigue, jaundice, dark urine, clay-colored stools, or itching.

Pregnancy

Consult your doctor or pharmacist before using a medicine.

Since metronidazole passes into the placenta and there is not enough data to establish its safety during pregnancy, your doctor will carefully weigh the convenience of using METRONIDAZOL SERRACLINICS 5 mg/ml during pregnancy.

Breast-feeding

Consult your doctor or pharmacist before using a medicine.

Metronidazole passes into breast milk, so its administration should be avoided during the breastfeeding period.

Driving and using machines:

If you experience any of the following side effects after taking METRONIDAZOL SERRACLINICS 5 mg/ml, such as confusion, dizziness, hallucinations, convulsions, and transient vision disorders, you should avoid driving vehicles or using machines.

Important information about some of the components of METRONIDAZOL SERRACLINICS 5 mg/ml:

This medicine contains 326 mg of sodium per 100 ml, which should be taken into account in patients with low-sodium diets.

Use of other medicines:

Tell your doctor or pharmacist if you are using or have recently used any other medicine, including those obtained without a prescription, homeopathic medicines, herbal remedies, and other health-related products, as it may be necessary to interrupt treatment or adjust the dose of one of them.

There is no therapeutic incompatibility with any of the anti-infectives commonly used. It can be administered simultaneously, although separately (i.e., not in the same container), with other anti-infectives.

The concomitant administration of metronidazole and disulfiram is not recommended, as cases of mental disorders have been reported.

Drinks and medicines containing alcohol should not be consumed during treatment with metronidazole until at least one day after treatment, due to the possibility of the so-called Antabus effect, a reaction characterized by flushing, vomiting, and tachycardia.

The concomitant administration of metronidazole and oral anticoagulant medicines (such as warfarin) may increase the risk of bleeding. If metronidazole is administered at the same time as these medicines, you should be closely monitored by your doctor.

There is a risk of increased blood levels of lithium (a medicine for depression) and cyclosporin (a medicine that decreases the body's defenses) when these medicines are administered concomitantly with metronidazole. Therefore, if they are administered concomitantly, it should be under strict medical control.

Phenytoin and phenobarbital (antiepileptic medicines) increase the elimination of metronidazole, thereby decreasing its blood levels.

Metronidazole increases the toxicity of fluorouracil.
