• If you are allergic (hypersensitive) to penicillin.
• If you are allergic (hypersensitive) to cephalosporins. Although an allergy to cephalosporins does not imply 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 during a previous antibiotic treatment (including another family of antibiotics), you have had any type of allergic reaction 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 renal impairment or liver impairment.

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

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

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

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

This information is intended solely for healthcare professionals:

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

Anaclosil must be reconstituted with water for injectable preparations (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 infusion.

Cloxacillin sodium should not be used in infusion bags that contain protein hydrolysates, lipid suspensions, amino acids, blood, or serum.

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

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

Reconstitution

To prepare the solution for slow intravenous administration (3-4 min.), a sterile technique should be followed. Reconstitute the vial contents with 4 mL of water for injectable preparations, and gently rotate until the powder is completely dissolved. Avoid shaking or making rapid movements, as this may cause foam formation. The reconstituted product is stable for a period of up to 6 hours at 25°C. From a microbiological standpoint, the reconstituted product should be administered immediately by direct intravenous injection or diluted immediately for continuous infusion administration.

Dilution

To administer by infusion, the reconstituted solution should be diluted in at least 100 mL of 0.9% sodium chloride solution or 50 mg/mL (5%) glucose infusion solution. Do not agitate the bag. The resulting solution is a transparent, colorless, or yellowish solution.

Infusion

Visual inspection should be performed to ensure that the reconstituted solution does not contain particles before administration. Solutions reconstituted with visible particles should be discarded.

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

Anaclosil should not be mixed with other medications.

Each vial is for single use only.
