Warnings and precautions

Consult your doctor, pharmacist, or nurse before receiving Amoxicillin/Clavulanic Acid if:

• you have infectious mononucleosis
• you are receiving treatment for liver or kidney problems
• you do not urinate regularly

If you are unsure if any of the above symptoms affect you, inform your doctor, pharmacist, or nurse before receiving amoxicillin/clavulanic acid.

In some cases, your doctor may investigate the type of bacteria causing your infection. Depending on the results, you may be prescribed a different formulation of amoxicillin/clavulanic acid or another medicine.

Symptoms to be aware of

Amoxicillin/Clavulanic Acid can worsen certain existing conditions or cause serious side effects. These include allergic reactions, seizures, and inflammation of the large intestine. You should be aware of certain symptoms while taking amoxicillin/clavulanic acid to reduce the risk of problems. See "Symptoms to be aware of" in section 4.

Blood and urine tests

If you are having blood tests (such as red blood cell studies or liver function tests) or urine tests (to check glucose levels), inform your doctor or nurse that you are being given amoxicillin/clavulanic acid. This is because amoxicillin/clavulanic acid can alter the results of these types of tests.

Other medicines and Amoxicillin/Clavulanic Acid NORMON

Tell your doctor, pharmacist, or nurse if you are using, have recently used, or might use any other medicines.

If you are taking allopurinol (used for gout) with amoxicillin/clavulanic acid, you may be more likely to have a skin allergic reaction.

If you are taking probenecid (used for gout), your doctor may adjust the dose of amoxicillin/clavulanic acid. Concomitant use of probenecid can reduce the excretion of amoxicillin and is not recommended.

If you are taking anticoagulants (such as warfarin) with amoxicillin/clavulanic acid, more blood tests will be needed.

Amoxicillin/Clavulanic Acid can affect the way metotrexate (a medicine used to treat cancer and severe psoriasis) works. Penicillins can reduce the excretion of metotrexate and cause a potential increase in side effects.

Amoxicillin/Clavulanic Acid can affect the way mycophenolate mofetil (a medicine used to prevent organ rejection in transplant patients) works.

This information is intended only for doctors or healthcare professionals:

Please see the Technical Data Sheet for additional information

Administration

Amoxicillin/Clavulanic Acid NORMON 500 mg/50 mg powder for solution for injection and perfusion can be administered by slow intravenous injection over a period of 3 to 4 minutes directly into a vein or by a drip for perfusion over 30 - 40 minutes. Amoxicillin/Clavulanic Acid NORMON is not suitable for intramuscular administration.

Reconstitution

The reconstitution of the solution for intravenous injection or the reconstitution and dilution of the solution for perfusion should be performed at the time of administration.

Preparation of solutions for intravenous injection

The usual solvent is water for injectable preparations. Amoxicillin/Clavulanic Acid NORMON 500 mg/50 mg should be dissolved in 10 ml of solvent. This results in approximately 10.5 ml of solution for single-dose use. A pale pink coloration may be observed during reconstitution. The reconstituted solutions are normally colorless or with a pale straw color.

Amoxicillin/Clavulanic Acid NORMON should be administered within 20 minutes after reconstitution.

Preparation of solutions for intravenous perfusion

Amoxicillin/Clavulanic Acid NORMON should be reconstituted as described above for injection. Immediatelyafter reconstitution, the solution should be added to 50 ml of perfusion fluid using a minibag or in-line burette.

Solutions for injection of glucose (dextrose), sodium bicarbonate, or dextran should not be used as solvents.

In general, it is recommended not to mix it with any other product in the same syringe or perfusion bottle. The combination of amoxicillin and clavulanic acid is incompatible with: blood and plasma, hydrocortisone succinate, amino acid solutions, protein hydrolysates, lipid emulsions, phenylephrine HCl, mannitol solutions.

AMOXICILLIN/CLAVULANIC ACID NORMON SHOULD NOT BE MIXED IN THE SAME SYRINGE WITH AMINOGLYCOSIDE ANTIBIOTICS, AS THIS MAY RESULT IN A LOSS OF ACTIVITY OF THE AMINOGLYCOSIDE.

The vials of Amoxicillin/Clavulanic Acid NORMON are not suitable for multiple-dose use.

Stability of Prepared Solutions

Reconstituted vials (for intravenous injection or before dilution for perfusion)

The solution obtained after reconstituting the vial with 10 ml of water for injectables has been shown to be stable from a chemical and physical point of view for 20 minutes at 25 °C ± 2°C / 60% ± 5% HR.

Reconstituted and diluted vials for perfusion

Reconstitution of the vial (see previous section).

The solution obtained by diluting immediatelythe reconstituted vial with 50 ml of water for injectables Ph. Eur. or NaCl 0.9% or sodium lactate 1/6 M or Ringer's solution or Hartmann's solution has been shown to be stable from a chemical and physical point of view for 60 minutes at 25°C ± 2°C / 60% ± 5% HR.
