Each Asiviral tablet encapsulates the potency of 400 mg of acyclovir. In this pharmaceutical ensemble, the active ingredient is complemented by excipients such as lactose, microcrystalline cellulose, povidone, sodium starch glycolate, and magnesium stearate.

Navigating Indications

Asiviral emerges as a stalwart against specific viral culprits, particularly Herpes Simplex Virus (HSV) types 1 and 2. Its therapeutic arm extends to the treatment of diverse maladies, encompassing skin infections like cold sores, the nuances of chickenpox, the intricacies of shingles, and the pursuit of healing in patients afflicted by severe immune system insufficiency, notably those following AIDS or bone marrow transplantation.


Asiviral holds a contraindication – a red flag for patients who have experienced an allergic reaction to acyclovir or its close counterpart, valacyclovir. Vigilance is paramount; if an allergic response unfurls during Asiviral use, marked by manifestations such as rash, localized pain, or swelling, discontinuation is advised, and immediate physician consultation becomes the need of the hour.

Pregnancy and Breastfeeding

Asiviral during pregnancy should be a calculated decision, leaning towards usage if the projected benefits outweigh the potential risks. If the course of treatment coincides with the onset of pregnancy, timely consultation with a healthcare provider or pharmacist is imperative. Caution is warranted in the realm of breastfeeding while under Asiviral‘s influence.

Side Effects

Common side effects of Asiviral include:

  • Headaches
  • Dizziness
  • Nausea or Vomiting
  • Diarrhea
  • Skin Sensitivity to Sunlight

This enumeration, however, is not exhaustive, and the spectrum of side effects may broaden. In such instances, healthcare providers serve as the compass, ensuring that the exhibited symptoms align with the personal medical circumstances. The diligent consulting of a healthcare professional is underscored, and avenues to report side effects to the FDA are accessible, guided by the number 1-800-FDA-1088.

Onset of Action

Asiviral, the harbinger of acyclovir, initiates its therapeutic orchestration upon entering the system. The tempo of symptomatic improvement, however, is a variable contingent on the nature and severity of the infection.

In the realm of acute Herpes Zoster, the norm is the administration of 800 mg every 4 hours, five times a day, spanning 7 to 10 days. For the contours of Genital Herpes, the initial treatment route calls for 200 mg every 4 hours, five times a day, across 10 days.

The characteristic of note is that while Asiviral orchestrates a reduction in the gravity and duration of outbreaks, it does not wield immediate alleviation. It operates by impeding viral replication, expediting sore healing, arresting the emergence of new sores, and curtailing discomfort and itching. Asiviral harbors a half-life ranging from 2.5 to 3.3 hours in those with normal renal function. This temporal metric signifies the duration for half of the drug to exit the system.

The constant undercurrent is the value of healthcare provider consultation, a pillar for information aligned with the personal medical trajectory.

The truth is that when we’re sick, or worried about getting sick, the internet won’t help.

According to Wikipedia, cyberchondria is a mental disorder consisting in the desire to independently make a diagnosis based on the symptoms of diseases described on Internet sites.

Why you can't look for symptoms on the Internet

If diagnoses could be made simply from a textbook or an article on a website, we would all be doctors and treat ourselves. Nothing can replace the experience and knowledge of specially trained people. As in any field, in medicine there are unscrupulous specialists, differences of opinion, inaccurate diagnoses and incorrect test results.
