Aciclovir – Antiviral Medication Overview

When working with Aciclovira synthetic antiviral medication that stops herpes virus replicationZovirax, you’re dealing with a drug that targets the DNA polymerase of herpes viruses. It is the drug of choice for infections caused by Herpes Simplex Virusthe virus behind cold sores and genital herpes and Varicella Zoster Virusthe virus that causes chickenpox and shingles. As an antiviral medicationa class of drugs that inhibit virus growth, Aciclovir blocks viral DNA polymerase, preventing the virus from multiplying (Aciclovir → blocks → viral DNA polymerase). This mechanism makes it effective for treating primary infections, recurrent outbreaks, and suppressive therapy. When you hear doctors mention Aciclovir, they’re referring to a medication that can be taken orally, applied as a cream, or given intravenously, each form tailored to the severity and location of the outbreak. Understanding these forms helps you match the treatment to the condition—topical creams for localized cold sores, oral tablets for genital herpes, and IV for severe immunocompromised cases.

Key Uses, Dosage Forms, and Safety Considerations

Aciclovir comes in three main formats: tablets (commonly 200 mg or 400 mg), topical creams (5% concentration), and injectable solutions for hospital use. The typical oral regimen for a first‑time genital herpes outbreak is 400 mg five times daily for ten days, while suppressive therapy may be 400 mg once daily. Topical application often involves five times a day for four days, starting at the first sign of a cold sore. Because the drug is eliminated through the kidneys, dose adjustments are crucial for patients with renal impairment to avoid accumulation and potential neurotoxicity. Common side effects include headache, nausea, and mild kidney irritation; serious adverse reactions such as confusion or seizures are rare but warrant immediate medical attention. Pregnant or breastfeeding women should consult their physician, as Aciclovir is generally considered safe but still requires professional guidance. Drug interactions can occur with medications like probenecid, which raises Aciclovir levels, and certain chemotherapy agents, so always disclose your full medication list.

Practical tips can make a big difference: start treatment at the first tingling or itching sensation for cold sores, keep the cream thinly spread to promote absorption, and stay hydrated to support kidney function during oral therapy. For people with frequent outbreaks, a daily suppressive dose can cut the number of episodes by up to 80 %. Monitoring kidney function through blood tests is advised for long‑term users, especially older adults.
