Why is this medication prescribed?

Nafcillin injection is a medication commonly prescribed to treat bacterial infections caused by susceptible strains of Staphylococcus aureus, including methicillin-resistant Staphylococcus aureus (MRSA). It belongs to the class of antibiotics known as penicillinase-resistant penicillins.

Nafcillin is primarily used for the treatment of skin and soft tissue infections, such as cellulitis, impetigo, and abscesses. It can also be used for respiratory tract infections, including pneumonia and bronchitis, as well as bone and joint infections, bloodstream infections, and endocarditis (infection of the heart valves).

How should this medicine be used?

The specific dosage and duration of treatment with Nafcillin injection depend on various factors, including the severity and location of the infection, the patient’s age, weight, and overall health condition, as well as the susceptibility of the infecting bacteria.

Nafcillin injection is typically administered by a healthcare professional, such as a doctor or nurse, either intravenously (IV) or intramuscularly (IM). The injection is usually given every 4 to 6 hours, but the exact dosing schedule will be determined by the prescribing healthcare provider.

It is important to follow the instructions provided by your healthcare professional regarding the proper use of Nafcillin injection. Do not self-administer this medication or change the dosage without consulting your doctor. Completing the full course of treatment is essential, even if you start feeling better before the prescribed duration, to ensure the infection is completely eradicated.

If you have any specific concerns or questions about the use of Nafcillin injection, it is best to consult your healthcare provider for accurate and personalized guidance.

Other uses for this medicine

Regarding other uses for Nafcillin Injection, it is primarily indicated for the treatment of staphylococcal infections. However, it is important to note that antibiotics should only be used to treat bacterial infections as prescribed by a healthcare professional. Nafcillin is not effective against viral infections, such as the common cold or flu.

What special precautions should I follow?

When using Nafcillin injection, certain precautions should be considered:

• Allergies: Inform your doctor if you have a known allergy to Nafcillin or any other penicillin antibiotics. If you have a history of severe allergic reactions (such as anaphylaxis), it may be necessary to avoid Nafcillin and use an alternative medication.
• Kidney and Liver Function: Nafcillin is primarily eliminated from the body through the kidneys. If you have impaired kidney function or liver disease, your doctor may need to adjust the dosage to prevent any potential complications.
• Interactions: Inform your doctor about all the medications you are currently taking, including prescription drugs, over-the-counter medications, and herbal supplements. Nafcillin may interact with certain medications, such as oral anticoagulants (blood thinners), and dose adjustments or alternative treatments may be necessary.
• Clostridium difficile Infection: Antibiotic use, including Nafcillin, can disrupt the normal balance of bacteria in the intestines and potentially lead to a Clostridium difficile infection. If you develop persistent diarrhea or abdominal pain during or after treatment, notify your doctor.
• Pregnancy and Breastfeeding: Nafcillin is generally considered safe to use during pregnancy and while breastfeeding. However, it’s essential to consult with your doctor to weigh the potential risks and benefits before using this medication.

It is crucial to follow your doctor’s instructions, complete the full course of treatment, and report any side effects or concerns during the use of Nafcillin injection.

What special dietary instructions should I follow?

However, if it is close to the time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not double the dose to make up for the missed one.
