Warnings and precautions

Consult your doctor before starting to take Flagyl 125 mg/ 5 ml oral suspension:

-If you have severe liver (hepatic) disorders.

-If your treatment is prolonged. Your doctor may request that you undergo regular blood tests, especially to monitor your white blood cell count. You will also be closely monitored for the risk of neurological conditions such as paresthesia (tingling in the feet or hands), ataxia (loss of coordination), dizziness, and seizures.

• If you have acute or chronic severe disorders of the central or peripheral nervous system, due to the possible risk of worsening.

-If you have severe kidney disorders. In this case, your doctor may reduce your dose when you are not undergoing dialysis or when your blood levels of this medication are not controlled.

• Your urine may darken.
• If you experience dizziness (sensation of spinning).
• This medication contains 600 mg/ml of saccharose, which should be taken into account in diabetic patients.

-Due to its ethanol content, this medication may pose a risk in patients with liver disease, alcoholism, epilepsy, and pregnant women and children.

Severe liver toxicity/acute liver insufficiency, some of which have a fatal outcome, have been described in patients with Cockayne syndrome who have taken metronidazole-containing medications.

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

Inform your doctor immediately and stop taking metronidazole if you experience:

• abdominal pain, anorexia, nausea, vomiting, fever, general malaise, fatigue, jaundice, dark urine, clay-colored stools, or itching.

Severe cutaneous bullous reactions, such as Stevens-Johnson syndrome (SSJ), toxic epidermal necrolysis (TEN), or generalized acute pustular exanthema (PEGA), have been reported with metronidazole. If you experience symptoms or signs of PEGA, SSJ, or TEN, discontinue treatment with Flagyl immediately.

Inform your doctor or nurse before undergoing blood tests, as Flagyl may alter the results of some blood tests.

Use of Flagyl 125 mg/ 5 ml oral suspension with other medications

Inform your doctor or pharmacist if you are taking or have taken recently or may need to take any other medication.

The concomitant administration of metronidazole and disulfiram (a medication used to help treat alcoholism) is not recommended, as cases of mental disorders have been reported.

Alcoholic beverages and medications containing alcohol should not be consumed during treatment with metronidazole for at least one day after treatment, due to the possibility of the Antabus effect, a reaction characterized by skin flushing, vomiting, and tachycardia.

The concomitant administration of metronidazole and oral anticoagulants (medications that help prevent blood clotting, such as warfarin) may increase the risk of bleeding. If you take metronidazole at the same time as these medications, you should be closely monitored by your doctor.

There is a risk of elevated blood levels of lithium (a medication for depression) and cyclosporine (a medication that reduces the body's defenses) when these medications are administered concomitantly with metronidazole. Therefore, if they are administered concomitantly, it should be under strict medical control.

Phenobarbital and phenytoin (antiepileptic medications) increase the elimination of metronidazole, thereby reducing its blood levels.

Metronidazole increases the toxicity of fluorouracil and busulfan (medications used to treat cancer).

Inform your doctor if you are taking any medication that may cause alterations in heart rhythm (prolongation of the QT interval, which can be seen on an ECG) as occurs with certain antiarrhythmics, certain antibiotics, and medications primarily used to control psychosis (including delusions, hallucinations, paranoia, or disordered thinking).

Pregnancy, breastfeeding, and fertility

Consult your doctor or pharmacist before using any medication.

As metronidazole crosses the placental barrier and there is insufficient data to establish its safety during pregnancy, your doctor will carefully evaluate the need to use Flagyl during pregnancy.

Metronidazole is excreted in breast milk, so it should be avoided during lactation.

Driving and operating machinery

During treatment with Flagyl, you may feel dizzy or experience dizziness (sensation of spinning), confusion, hallucinations (seeing or hearing things that do not exist), seizures (having attacks), or vision problems (such as blurred vision or double vision). If this occurs, do not drive vehicles or operate machinery.

Flagyl 125 mg/5 ml oral suspension contains saccharose, ethanol, propyl and methyl parahydroxybenzoate, and sodium:

- 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.

Patients with diabetes mellitus should note that this medication contains 3 g of saccharose per 5 ml of metronidazole.

- This medication contains 6.28 mg of alcohol (ethanol) per ml of oral suspension, which is equivalent to 0.6% (p/v). The amount in one ml of oral suspension of this medication is equivalent to less than 0.15 ml of beer or 0.06 ml of wine.

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

- Allergic reactions (possibly delayed) may occur because it contains propyl parahydroxybenzoate (E-216) and methyl parahydroxybenzoate (E-218).

- This medication contains less than 23 mg of sodium (1 mmol) per ml of oral suspension; it is essentially "sodium-free".
