6.Contents of the pack and additional information

1. What is Zepilen and how is it used

Zepilen is a powder for the preparation of an injectable solution that contains the active ingredient cefazolin (as cefazolin sodium).

Cefazolin is an antibiotic medication and belongs to a group of medications called cephalosporins. Zepilen treats certain infections.

Antibiotics are used to treat bacterial infections and do not work to treat viral infections such as the flu or a cold.

It is essential to follow the instructions regarding the dose, administration interval, and treatment duration indicated by your doctor.

Do not store or reuse this medication. If you have leftover antibiotic after treatment, return it to the pharmacy for proper disposal. Do not dispose of medications through the drain or trash.

Zepilen is used to treat the following infections:

  • Skin and soft tissue infections
  • Bone and joint infections
  • Infections caused by, or as a precaution against the development of an infection before, during, or after surgery.

2. What you need to know before starting to use Zepilen

Do not use Zepilen:

  • if you are allergic to cefazolin, other cephalosporins, or any of the other components of this medication (including those in section6).
  • if you have had an immediate and/or severe allergic reaction to penicillin or another type of beta-lactam antibiotic.
  • Cefazolin should not be dissolved in lidocaine solution for administration to children under 1 year.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to use Zepilen:

  • If you have a history of allergic reactions to penicillins or other medications, you may also be allergic to cefazolin. Treatment with this medication should be interrupted if an allergic reaction occurs, the allergic reaction should be treated, and renal function should be checked.
  • In the case of an allergic reaction due to cefazolin, administration of the product will be interrupted. Your doctor will propose an alternative treatment.
  • If you are administered the maximum dose and are severely ill or taking other medications that can be harmful to the kidneys (aminoglycosides or strong diuretics), your doctor will check your renal function and adjust the dose if necessary.
  • If cefazolin is administered for a prolonged period, your doctor will check that non-susceptible bacteria do not grow uncontrollably.
  • In some cases, bleeding disorders may occur during treatment with cefazolin. This risk is especially present if you have risk factors that cause vitamin K deficiency or risk factors that affect other mechanisms of blood coagulation. Additionally, blood coagulation may be affected in patients with disorders that cause or exacerbate bleeding, such as hemophilia, stomach and intestinal ulcers. In these cases, your blood coagulation will be monitored.
  • You may experience persistent and severe diarrhea after treatment with cefazolin, caused by inflammation of the small and large intestine that causes damage to the mucous membranes (pseudomembranous colitis).

Consult your doctor if any of the above warnings apply to you or if they have applied to you in the past.

Children and adolescents

Cefazolin should not be used in neonates (newborns and children under 1 month), as the safety of use has not been established in this group.

Use of Zepilen with other medications

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication.

Contraindicated combinations

  • If you are taking antibiotics from certain groups (bacteriostatic agents) simultaneously, such as tetracyclines and macrolides, these may counteract the effect of cefazolin, making cefazolin less effective.

Not recommended combinations

  • Simultaneous use of probenecid (for a metabolic disorder) may inhibit the excretion of cefazolin by the kidneys.

Use with caution

  • If you are taking vitamin K1, cefazolin may cause an increase in vitamin K1 concentrations.
  • Cephalosporins rarely may cause blood coagulation disorders. When administered together with anticoagulant medications (oral anticoagulants or heparin) in high doses, coagulation values should be monitored.
  • If you take medications that have a nephrotoxic effect (toxic to the kidneys), such as certain antibiotics (aminoglycosides, polymyxin B) and certain diuretics (furosemide), renal function should be monitored during concomitant use.
  • Cefazolin may have an adverse effect on the effectiveness of hormonal contraceptives. Therefore, it is recommended to use non-hormonal supplementary contraceptives.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, or if you think you may be pregnant, consult your doctor or pharmacist before using this medication.

There are not enough data on the use of cefazolin during human pregnancy to evaluate the possible harm.

Zepilen should not be taken during pregnancy without a doctor's recommendation.

Cefazolin is excreted in breast milk in low concentrations, but it is not expected to affect breastfed infants. If you are pregnant or breastfeeding, your doctor will decide if cefazolin is suitable for you.

Driving and operating machinery

No studies have been conducted on the effects on the ability to drive and operate machinery.

There are no data on the effects of cefazolin on the ability to drive or operate machinery. However, it is unlikely that effects will occur.

Zepilen contains sodium

This medication contains 50.6 mg of sodium (main component in cooking/salt) in each vial, which is equivalent to 2.53% of the maximum daily recommended sodium intake in an adult diet.

3. How to use Zepilen

Follow exactly the administration instructions of this medication as indicated by your doctor.In case of doubt, consult your doctor or pharmacist again.

This medication will be administered by a qualified person, such as a doctor or nurse.

The recommended dose is:

Adults

  • Highly susceptible bacterial infections: 1 g to 2 g per day in two or three equal doses.
  • Less susceptible bacterial infections: 3 g to 4 g per day in three or four equal doses. If necessary, in severe cases, the total daily dose can be increased up to 6 mg per day.
  • As a precaution against infection:
  • Before surgery: 1 g administered 30 minutes to 1 hour before the start of surgery;
  • During surgery: for a prolonged operation (e.g., 2 hours or more), 500 mg to 1 g will be administered with a duration depending on the duration of the operation;
  • After surgery: between 500 mg and 1 g administered every 6 to 8 hours for 24 hours.

A lower dose may be necessary in adults with impaired renal function.

The dose is determined based on blood levels or renal function values.

Use in children and adolescents

Preterm and Neonates

Safety has not been determined in children under one month.

Infants

The doctor will determine the dose based on the child's body weight. The daily dose for children can range from 25 to 50 mg per kilogram of body weight. Depending on the severity of the infection, this dose can be increased to 100 mg per kilogram of body weight.

Older adults

No dose adjustment is necessary in patients with normal renal function.

Treatment duration

The treatment duration depends on how the disease develops. In accordance with the general principle of antibiotic treatment, cefazolin treatment should continue for at least 2 to 3 days after the fever has subsided or until it is demonstrated that the cause has been controlled.

If you use more Zepilen than you should

If you have been administered too much Zepilen, contact your doctor immediately. High doses of cefazolin can cause seizures, especially in patients with impaired renal function. In this case, cefazolin treatment should be discontinued and appropriate treatment should be administered. Vital functions will be checked.

If you forget to use Zepilen

If you think you have not received a dose of cefazolin, inform your doctor immediately.

If you interrupt Zepilen treatment

It is essential to complete a full treatment, even if you feel better before. If not all bacteria are eliminated, symptoms may return.

If you have any other questions about the use of this medication, ask your doctor, pharmacist, or nurse.
