Acyclovir offers targeted treatment for herpes simplex viruses and varicella-zoster virus. It works by hindering viral replication, which reduces symptoms and speeds up recovery. Prescribing acyclovir is straightforward, but a proper understanding of the dosage and administration is crucial for optimal results.
For adults managing an initial outbreak of genital herpes, the recommended dosage is typically 400 mg taken three times a day for seven to ten days. In cases of recurrent outbreaks, a lower dose of 800 mg taken twice daily for five days can be effective. Always advise patients to start the treatment as soon as symptoms appear for maximum benefits.
When prescribing acyclovir, consider renal function. Patients with impaired kidney function may require dosage adjustments to prevent toxicity. Ensure they stay well-hydrated during treatment to further support renal function. Discuss potential side effects, such as nausea or dizziness, and provide guidance on what to do if they occur.
In cases where patients might require long-term suppression therapy, taking acyclovir 400 mg twice daily can significantly reduce the frequency of outbreaks. Regular follow-ups can help assess treatment efficacy and make necessary modifications. By guiding patients correctly, you can enhance their treatment experience and improve outcomes.

Prescription for Acyclovir
To treat herpes simplex virus infections, including genital herpes, the standard prescription for adults is 400 mg of acyclovir taken orally three times a day for 7 to 10 days. For recurrent outbreaks, a shorter course of 400 mg taken three times daily for 5 days is recommended.
Dosing Adjustments
For individuals with renal impairment, dosage adjustments are necessary. Typically, reduction in dosage can be made based on creatinine clearance levels. For patients with a clearance of less than 10 mL/min, the dosage usually decreases to 200 mg every 12 hours.
Prophylaxis Recommendations
During periods of frequent outbreaks, consider a prophylactic treatment. A daily dose of 200 mg taken twice daily can be prescribed to help reduce the frequency of outbreaks. This regimen might extend over several months to maintain effectiveness.
Monitor hydration levels during treatment as acyclovir may lead to nephrotoxicity if excessive amounts are administered without adequate fluid intake.
Understanding Indications for Acyclovir Use
Acyclovir is primarily used for the treatment of infections caused by certain types of viruses. Here are the key indications for its use:
- Herpes Simplex Virus (HSV):
- Effective against both HSV-1 and HSV-2.
- Indicated for the management of first episode genital herpes.
- Useful for recurrent episodes, reducing duration and severity of symptoms.
- Recommended as a prophylactic treatment for individuals with frequent outbreaks.
- Varicella-Zoster Virus (VZV):
- Prescribed for chickenpox (varicella) in children and adults.
- Utilized in the treatment of shingles (herpes zoster) to alleviate pain and hasten healing.
- Cytomegalovirus (CMV):
- Often recommended for the prevention and treatment of CMV infection in immunocompromised patients.
- Helpful in managing CMV retinitis in individuals with AIDS.
Dosage and duration depend on the type and severity of the infection. Always consult a healthcare provider to determine the appropriate treatment plan.
Be aware of potential side effects, which may include gastrointestinal disturbances and neurological effects, especially in cases of rapid infusion. Monitoring renal function is also advisable due to the drug’s renal clearance.
Dosage Guidelines and Administration for Acyclovir
The standard oral dosage for adults with genital herpes is 400 mg taken three times daily for 7 to 10 days. For recurrent episodes, patients can take the same dose for 5 days. In the case of severe herpes simplex infections, intravenous administration is recommended, typically at a dose of 5 to 10 mg/kg every 8 hours based on the patient’s renal function.
Dosage for Specific Conditions
For varicella (chickenpox) in children, the recommended oral dosage is 20 mg/kg, given four times a day for 5 days, not exceeding a total of 800 mg per day. In immunocompromised individuals, such as those undergoing chemotherapy, the intravenous dosage may increase, depending on individual health status. Monitor renal function closely to avoid toxicity.
Administration Tips
Administer acyclovir with a full glass of water to enhance hydration. For oral doses, take the medication with or without food; however, consistent timing helps maintain effective blood levels. Ensure to complete the full course of therapy, even if symptoms improve. Regular assessments of kidney function should take place throughout treatment, especially in patients with pre-existing renal impairment.
Potential Side Effects and Monitoring While on Acyclovir
While taking acyclovir, pay close attention to any side effects that may arise. Common side effects include nausea, diarrhea, and headache. These symptoms often resolve themselves as your body adjusts to the medication. However, if they persist or worsen, consult your healthcare provider.
More serious side effects can occur, such as kidney problems. Monitor your fluid intake and ensure you stay well-hydrated. Report any sudden changes in urination, increased fatigue, or swelling in your legs and ankles. These could indicate renal strain.
Regular Monitoring
Regular blood tests can help track your kidney function while on acyclovir. Your doctor may recommend these tests before starting treatment and periodically afterward, especially if you have pre-existing kidney conditions. Early detection of any irregularities can prevent severe complications.
Allergic reactions, although rare, can happen. Watch for symptoms like rash, itching, or difficulty breathing. If these arise, seek immediate medical attention.
Communication with Your Healthcare Provider
Keep your healthcare provider informed about all medications and supplements you are taking. Some interactions may amplify side effects or reduce the effectiveness of acyclovir. Regular communication ensures safe and effective management of your condition.
