ARCHIFAR 1G POWDER FOR INJECTABLE SOLUTION AND FOR INFUSION

2. What you need to know before you use Archifar

Do not use Archifar:

• if you are allergic to meropenem or any of the other ingredients of this medicine (listed in section 6).
• if you are allergic to other antibiotics such as penicillins, cephalosporins, or carbapenems, as you may also be allergic to meropenem.

Warnings and precautions

Talk to your doctor or nurse before starting Archifar if:

• you have health problems, such as liver or kidney problems.
• you have had severe diarrhea after taking other antibiotics.

You may develop a positive response to a test (Coombs test) that indicates the presence of antibodies that can destroy red blood cells. Your doctor will discuss this with you.

If you are in any of these situations or have doubts, consult your doctor or nurse before using Archifar.

Using Archifar with other medicines

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

This is because Archifar can affect how some medicines work, and some of these may have an effect on Archifar.

In particular, tell your doctor or nurse if you are taking any of the following medicines:

• Probenecid (used to treat gout).
• Valproic acid/sodium valproate/valpromide (used to treat epilepsy). Archifar should not be used, as it can decrease the effect of sodium valproate.
• Oral anticoagulant agent (used to treat or prevent blood clots).

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine. It is preferable to avoid using meropenem during pregnancy.

Your doctor will decide whether you should use Archifar.

It is very important that you inform your doctor if you are breastfeeding or plan to breastfeed, before receiving treatment with meropenem. A small amount of this medicine may pass into breast milk. Therefore, your doctor will decide whether you should use Archifar during breastfeeding.

Driving and using machines

No studies on the effects on the ability to drive and use machines have been performed.

Archifar has been associated with headache and tingling or numbness of the skin (paresthesia). Either of these side effects could affect your ability to drive or use machines.

Archifar may cause involuntary muscle movements, which can cause the body to shake rapidly and uncontrollably (convulsions). This is usually accompanied by a loss of consciousness. Do not drive or use machines if you experience this side effect.

Archifar contains sodium

Archifar 500 mg contains approximately 45 mg of sodium (main component of cooking/table salt) per vial. This is equivalent to 2.25% of the maximum recommended daily dietary intake of sodium for an adult.

Archifar 1 g contains approximately 90 mg of sodium (main component of cooking/table salt) per vial. This is equivalent to 4.5% of the maximum recommended daily dietary intake of sodium for an adult.

3. How to use Archifar

Follow exactly the administration instructions for this medicine as indicated by your doctor. If in doubt, consult your doctor or pharmacist again.

Health Advice/Education

Antibiotics are used to treat infections caused by bacteria. They have no effect on infections caused by viruses.

Sometimes a bacterial infection does not respond to treatment with an antibiotic. One of the most common reasons for this is that the bacteria causing the infection are resistant to the antibiotic being taken. This means they can survive and even multiply, despite the antibiotic.

Bacteria can become resistant to antibiotics for many reasons. Using antibiotics with caution can help reduce the opportunity for bacteria to become resistant to them.

When your doctor prescribes antibiotic treatment, it is to treat only your current illness. Paying attention to the following tips will help prevent the appearance of resistant bacteria that could stop the antibiotic from working.
