Acyclovir is a prescription antiviral medication, primarily used to treat herpes simplex virus (HSV) infections, including oral herpes (cold sores) and genital herpes. It also treats chickenpox and shingles (herpes zoster).
How Acyclovir Works
Acyclovir inhibits viral DNA replication. Specifically, it’s a nucleoside analog that competes with deoxyguanosine, a building block of viral DNA. This stops the virus from multiplying, reducing the severity and duration of symptoms.
Forms and Administration
Acyclovir comes in various forms: oral tablets, capsules, topical creams, and intravenous infusions. The chosen form depends on the type and severity of the infection. Oral forms are common for treating oral or genital herpes, while intravenous administration is reserved for severe cases, like disseminated herpes. Topical creams provide localized relief for cold sores.
Dosage and Treatment Duration
- Oral Herpes: Typical treatment involves several days of oral medication, with dosage varying depending on the severity of the outbreak. Your doctor will provide specific instructions.
- Genital Herpes: Similar to oral herpes, the treatment duration depends on the severity. Suppressive therapy, involving daily medication, may be used to reduce the frequency of outbreaks.
- Chickenpox and Shingles: Oral acyclovir is used to shorten the duration and severity of these infections, typically for 7-10 days. Early treatment is crucial for optimal results.
Side Effects
Common side effects include nausea, headache, and diarrhea. More serious side effects are rare but can include kidney problems and neurological issues. Report any concerning side effects to your doctor immediately.
Important Considerations
- Acyclovir doesn’t cure herpes; it manages symptoms and reduces outbreaks.
- It’s not effective against all viruses.
- Always follow your doctor’s instructions precisely regarding dosage and treatment duration.
- Inform your doctor about all other medications you are taking.
Alternatives and Consultations
Other antiviral medications, like valacyclovir and famciclovir, are available to treat similar infections. Your doctor can help determine the best treatment option for your specific needs. Always consult a healthcare professional for diagnosis and treatment of any viral infection.

Seeking Professional Help
For accurate diagnosis and personalized treatment, schedule an appointment with your physician or a qualified healthcare provider. They can assess your condition and recommend the appropriate course of action.
Potential Side Effects and Precautions
Acyclovir generally causes mild side effects. However, some individuals experience more pronounced reactions. Common side effects include headache, nausea, and diarrhea. These usually resolve without intervention. Less frequently, people report dizziness, fatigue, and vomiting.
Kidney Issues
Acyclovir can sometimes affect kidney function, particularly with high doses or in individuals with pre-existing kidney problems. Drink plenty of fluids while taking acyclovir to help your kidneys flush out the medication. Inform your doctor about any kidney problems before starting treatment.
Neurological Effects
Rarely, acyclovir can cause neurological side effects, such as confusion, hallucinations, seizures, and tremors. This is more likely in individuals with impaired kidney function or those receiving high doses. Stop taking acyclovir and contact your doctor immediately if you experience these symptoms.
Always inform your doctor about all medications you are currently taking, including over-the-counter drugs and supplements. This helps avoid potential interactions. Pregnancy and breastfeeding require special consideration; consult your physician before using acyclovir during these periods. Allergic reactions, though uncommon, can occur. Seek immediate medical attention if you experience symptoms like rash, itching, or swelling.
