What Is Aciclovir 200mg?

Aciclovir 200mg is an oral antiviral medicine frequently prescribed to manage viral infections caused by the herpes virus group.

Aciclovir (also known as acyclovir) belongs to the class of medications known as synthetic nucleoside analogues. It is designed to limit the replication of certain viruses, making it essential in treating recurring and initial episodes of viral infections. Aciclovir is included in the World Health Organization’s List of Essential Medicines for its importance in public health.

How Does Aciclovir Work?

Aciclovir works by interfering with the ability of herpes viruses to multiply, thus reducing the severity and duration of infections[2][3][7].

Once in the body, aciclovir targets viral DNA synthesis, effectively stopping the virus from making copies of itself. This action helps:

Shorten the length of outbreaks
Lessen the intensity of symptoms such as pain, itching, and blisters
Decrease the risk of complications, especially in immunocompromised patients
Reduce the likelihood of transmitting the infection to others, though it does not eliminate the risk entirely

It’s crucial to note that aciclovir does not cure herpetic infections; the viruses remain dormant in the body and can reactivate later[2][7].

Key Medical Uses of Aciclovir 200mg Tablets

Aciclovir 200mg tablets are used for treating several viral infections, predominantly those caused by the herpes virus family[1][2][3][5][7]:

1. Genital Herpes (Herpes Simplex Virus Type 2 and Type 1)

Used to treat both the initial and recurrent outbreaks of genital herpes.
Can be prescribed for long-term suppression to prevent frequent recurrences, especially in immunocompetent individuals[5][7].

2. Cold Sores (Herpes Labialis)

Treats flare-ups of cold sores caused by herpes simplex virus type 1.
Effective especially when started at the first sign of symptoms[1][2][3].

3. Chickenpox (Varicella Zoster Virus)

Prescribed especially for adults, adolescents, and at-risk children where chickenpox may be more severe[1][5][7].

4. Shingles (Herpes Zoster Virus)

Used to manage outbreaks of shingles, helping reduce pain, rash severity, and risk of long-term nerve complications[1][5][7].

5. Herpes Simplex Prophylaxis

Given to immunocompromised patients (e.g., those with HIV/AIDS, cancer treatment, or organ transplants) to prevent herpes virus infections[5][7].

6. Other Uses

Occasionally prescribed for non-genital herpes infections, such as those affecting the mouth, nose, or eyes (e.g., herpetic keratitis)[3][7].
May be used in special situations for herpes simplex encephalitis or eczema herpeticum, always under specialist care[2][7].
