Why is this medication prescribed?

Unasyn is a combination antibiotic medication that is prescribed to treat bacterial infections. It contains two active ingredients: ampicillin and sulbactam. The combination is effective against a variety of bacteria, and its use is typically reserved for infections caused by organisms that may be resistant to standard antibiotics. Here are some common reasons why Unasyn might be prescribed:

  • Bacterial Infections: Unasyn is often used to treat various types of bacterial infections, including respiratory tract infections, skin and soft tissue infections, urinary tract infections, intra-abdominal infections, and gynecological infections.
  • Mixed Infections: In cases where the infection involves a mix of bacteria, including some that may produce beta-lactamase (an enzyme that can inactivate certain antibiotics), the addition of sulbactam helps to enhance the effectiveness of ampicillin by inhibiting the beta-lactamase enzymes.
  • Hospital-Acquired Infections: Unasyn may be used for treating infections acquired in a hospital setting, where there is a higher likelihood of encountering bacteria that are resistant to standard antibiotics.

How should this medicine be used?

The usage of Unasyn (ampicillin-sulbactam) should be strictly according to your healthcare provider’s prescription. Dosage and administration may vary based on the type and severity of the infection, the specific bacteria involved, and individual patient factors. Always follow your healthcare provider’s instructions and read the medication guide provided by the pharmacist. Here are general guidelines for the use of Unasyn:

  • Dosage: The dosage of Unasyn is determined by your healthcare provider based on factors such as the type and severity of the infection, your age, weight, and overall health. The dosage may be given intravenously (IV) or intramuscularly (IM) in a healthcare setting, or in some cases, it may be prescribed as oral tablets.
  • Administration: If Unasyn is administered intravenously or intramuscularly, it will be given by a healthcare professional in a hospital or clinic setting. The healthcare provider will follow proper procedures for administration.
  • Oral Administration: If Unasyn is prescribed in oral form, it is usually taken with a full glass of water, either with or without food. Follow the prescribed dosage and schedule precisely.
  • Completion of Course: It’s important to complete the entire course of Unasyn, even if you start feeling better before the medication is finished. Stopping antibiotics prematurely can lead to incomplete eradication of the infection and may contribute to antibiotic resistance.
  • Missed Dose: If you miss a dose, take it as soon as you remember. However, if it’s almost time for your next dose, skip the missed dose and resume your regular dosing schedule. Do not double up on doses to make up for a missed one.
  • Storage: Store Unasyn at room temperature, away from moisture and heat. Follow any specific storage instructions provided by your pharmacist.
  • Consultation: Keep your healthcare provider informed about any side effects or changes in your condition. If you have concerns or questions about your medication, consult your healthcare provider or pharmacist.

It’s crucial to use Unasyn exactly as prescribed and to communicate with your healthcare provider throughout the course of treatment. If you have any questions or concerns about the medication, don’t hesitate to discuss them with your healthcare provider.

Other uses for this medicine

While Unasyn is primarily indicated for bacterial infections, its use may extend to various specific conditions, including:

  • Skin and Soft Tissue Infections: Unasyn is often prescribed for skin and soft tissue infections caused by susceptible bacteria.
  • Intra-abdominal Infections: It may be used for intra-abdominal infections, such as peritonitis, when caused by susceptible bacteria.
  • Respiratory Tract Infections: Unasyn can be employed in the treatment of respiratory tract infections, particularly lower respiratory tract infections.
  • Urinary Tract Infections: In certain cases, Unasyn may be used to treat urinary tract infections caused by susceptible bacteria.

What special precautions should I follow?

It’s essential to take certain precautions while using Unasyn. These precautions help ensure the effectiveness of the medication and minimize potential side effects. Here are some special precautions to consider:

  • Allergies: Inform your healthcare provider of any allergies to antibiotics, especially penicillins, cephalosporins, or other substances.

  • Interactions with Other Medications: Inform your healthcare provider of all medications, supplements, or herbal products you are taking, as Unasyn may interact with certain drugs.
  • Monitoring: Your healthcare provider may monitor your liver and kidney function, especially if you are on a prolonged course of Unasyn.
  • Complete the Course: Finish the entire course of Unasyn as prescribed by your healthcare provider, even if symptoms improve before completion. Stopping antibiotics prematurely may lead to incomplete eradication of the infection and the development of antibiotic resistance.
