Why is this medication prescribed?

Zovirax (acyclovir) is an antiviral medication that is primarily used to treat infections caused by the herpes simplex virus, including genital herpes, cold sores, shingles (herpes zoster), and chickenpox. Zovirax works by inhibiting the replication of the virus, thereby reducing the severity and duration of the infection.

Zovirax Injection is typically prescribed for severe cases of herpes infections, especially when the patient is unable to take the medication orally or when intravenous administration is considered more appropriate. Injections may be used in cases of severe herpes zoster (shingles), particularly when the virus affects the eyes or other vital organs.

How should this medicine be used?

Here are general guidelines on how Zovirax Injection is used:

  • Administration: Zovirax Injection is usually administered by a healthcare professional, often in a hospital setting.
  • Dosage: The dosage will depend on the specific condition being treated, the patient’s weight, and the severity of the infection. The healthcare provider will determine the appropriate dose.
  • Frequency of Administration: The injection is typically given every 8 hours.
  • Duration of Treatment: The duration of treatment with Zovirax Injection will be determined by the healthcare provider based on the patient’s response to the medication and the nature of the infection.

It’s crucial to follow the healthcare provider’s instructions and complete the entire course of treatment, even if symptoms improve before the medication is finished.

As with any medication, Zovirax may cause side effects, and it is important to report any unusual or severe reactions to a healthcare professional promptly. Additionally, it’s essential to inform the healthcare provider about any other medications or medical conditions you may have to avoid potential interactions or complications.

Please note that this information is a general guideline, and specific instructions may vary based on individual cases. Always follow the advice and prescriptions provided by your healthcare provider.

Other uses for this medicine

In addition to treating herpes simplex infections, Zovirax Injection may be used for severe cases of herpes zoster (shingles), particularly when the virus affects the eyes or other vital organs.

What special precautions should I follow?

  • Medical History: Inform your healthcare provider about your medical history, especially if you have kidney problems, are pregnant, or are breastfeeding.
  • Allergies: Inform your healthcare provider if you are allergic to acyclovir or any other medications.
  • Kidney Function: Since acyclovir is primarily excreted through the kidneys, patients with impaired kidney function may require dosage adjustments. Regular monitoring of kidney function may be necessary.
  • Pregnancy and Breastfeeding: If you are pregnant, planning to become pregnant, or breastfeeding, discuss the risks and benefits of Zovirax Injection with your healthcare provider.
  • Drug Interactions: Inform your healthcare provider about all the medications, supplements, and herbal products you are taking, as Zovirax may interact with certain drugs.

Always follow your healthcare provider’s recommendations and prescription instructions closely. If you experience any side effects or have concerns about the medication, contact your healthcare provider promptly. This information is general, and individual circumstances may vary, so it’s important to consult with a healthcare professional for personalized advice.

What special dietary instructions should I follow?

However, it’s always a good idea to consult with your healthcare provider or pharmacist, as individual cases may vary. Drinking plenty of water is generally recommended to stay hydrated, especially if you are receiving intravenous medication.

Common side effects of Zovirax Injection may include:
