1. What Anaclosil is and what it is used for

The active substance of Anaclosil is cloxacillin.

Cloxacillin is an antibiotic belonging to the penicillin family.

Anaclosil is indicated for the treatment of the following infections:

• Bone and joint infections.
• Sepsis: Severe infections with systemic impact.
• Endocarditis: Infections of a part of the heart called the endocardium.
• Meningitis: Infection of the membranes covering the nervous system.
• Genital and urinary tract infections.
• Respiratory infections.
• Skin and soft tissue infections.

Anaclosil is also indicated for the prevention of infections after neurological interventions such as internal cerebrospinal fluid diversion.

2. Before taking Anaclosil

Do not take Anaclosil:

• If you are allergic to the active substance.
• If you are allergic (hypersensitive) to penicillin.
• If you are allergic (hypersensitive) to cephalosporins. Although allergy to cephalosporins does not presuppose the existence of an allergy to this penicillin, it should be determined if the patient has previously experienced immediate, moderate, or severe allergic reactions to a cephalosporin, in which case it would be recommended to avoid the use of this penicillin.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to use Anaclosil if you:

• Are allergic to a specific group of antibiotics called beta-lactams (penicillins or cephalosporins).

• If you have had any type of allergic reaction during previous antibiotic treatment (even with another family of antibiotics), such as urticaria or other rashes, itching, sudden swelling of the face and neck.

• Suffer from kidney or liver disease.

• If you have a history of seizures and/or epilepsy, especially in patients with impaired renal or hepatic function.

• Are taking oral contraceptives, it is recommended to use an alternative, effective, and safe method during treatment and until one week after, as the concomitant use of Cloxacillin and combined oral contraceptives could decrease the effectiveness of the contraceptive.

This medicine may interfere with laboratory tests: If you are going to have any diagnostic tests (including blood tests, urine tests, etc.), inform your doctor that you are taking this medicine, as it may alter the test results.

Children and adolescents

This medicine should be administered with caution in neonates, due to the risk of hyperbilirubinemia due to competition at the bilirubin binding sites to serum proteins.

Other medicines and Anaclosil

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, including those obtained without a prescription. It is especially important that you inform your doctor if you are taking:

• Methotrexate, which is a medicine indicated for some forms of arthritis and for the treatment of psoriasis.
• Other antibiotics (medicines used for infections caused by bacteria), such as chloramphenicol, tetracyclines, macrolides, or sulfonamides. These antibiotics may decrease the effect of Anaclosil.
• Aminoglycosides, as treatment should be administered separately from Anaclosil.
• Probenecid, which is a medicine for the treatment of gout, as it may increase the effect of Anaclosil.
• Warfarin or other anticoagulant medicines.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, or think you may be pregnant, or are planning to have a baby, ask your doctor for advice before taking this medicine.

This medicine passes into breast milk. Ask your doctor for advice before breastfeeding your baby. Treatment should be discontinued in case of diarrhea, candidiasis, or skin rashes in the baby.

Driving and using machines

There is no evidence of effects on the ability to drive or use machines.

Anaclosil contains sodium

This medicine contains 52.8 mg of sodium (main component of kitchen/table salt) per vial. This is equivalent to 2.7% of the maximum recommended daily dietary intake of sodium for an adult.

Anaclosil will be administered to you by a qualified healthcare professional (doctor or nurse).

It will be administered directly (by intravenous direct route) over 3-4 minutes or by drip into a vein (intravenous perfusion) over approximately 1 hour.

The recommended dose for adults will be as follows:

• In the treatment of infections: 2,000 mg every 4-6 hours.
• In the prevention of infections before a neurological operation: a dose of 2,000 mg of Anaclosil before the intervention, and 1,000 mg every 2 hours during the intervention if it is prolonged.

In case of severe kidney and liver problems, the dose administered will be half of the recommended dose.

Detailed and updated information on this medicine is available on the website of the Spanish Agency for Medicines and Health Products (AEMPS) http://www.aemps.es

-------------------------------------------------------------------------------------------------------------------

This information is intended only for healthcare professionals:

Important: Consult the technical data sheet/summary of product characteristics before prescribing the medicine.

Anaclosil should be reconstituted with water for injections (for slow intravenous administration) and then diluted in at least 100 mL of sodium chloride 9 mg/mL (0.9%) or glucose 50 mg/mL (5%) for perfusion.

Sodium cloxacillin should not be used in perfusion bags containing protein hydrolysates, lipid suspensions, amino acids, blood, or serum.

The mixture of cloxacillin and aminoglycosides can cause substantial mutual inactivation, so they should not be mixed in the same perfusion bag.

Only limited data are available on the compatibility of Anaclosil with other substances for intravenous administration; consequently, no additives or other medicines should be added to the Anaclosil single-dose vials, nor should they be perfused simultaneously. If the same intravenous line is used for the sequential perfusion of different medicines, the line should be flushed before and after perfusion with a 0.9% sodium chloride solution.

Reconstitution

To prepare the solution for slow intravenous administration (3-4 minutes), an aseptic technique should be followed. Reconstitute the vial contents with 4 mL of water for injections, and gently rotate until the powder is completely dissolved. Avoid shaking or making rapid movements, as this could cause foam formation. The reconstituted product is stable for up to 6 hours at 25°C. From a microbiological point of view, the reconstituted product should be administered immediately by intravenous direct route or diluted immediately for continuous perfusion administration.

Dilution

For perfusion administration, the reconstituted solution should be diluted in at least 100 mL of sodium chloride 0.9% or glucose 5% solution for perfusion. Do not shake the bag. The resulting solution is a clear, colorless, or light yellow solution.

Perfusion

Check visually that the reconstituted solution does not contain particles before administration. Reconstituted solutions containing visible particles should be discarded.

Anaclosil should be administered as an intravenous perfusion over approximately 1 hour.

Anaclosil should not be mixed with other medicines.

Each vial is for single use only.
