Lavirk (Aciclovir)

Aciclovir, the active ingredient in Lavirk, is an antiviral presented as a topical formulation for topical use. It treats herpes simplex virus infections of the skin, mucous membranes and eyes, including cold sores, genital herpes and ocular herpes, helping to reduce lesion duration and symptom severity.

GNH USA supplies Lavirk as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The product conforms to EU regulatory standards and is manufactured under GMP conditions.

Aciclovir is used to manage viral infections caused by herpes simplex viruses affecting the skin and mucous membranes. - Herpes labialis (cold sores): shortens healing time and eases pain. - Genital herpes (initial outbreaks): reduces lesion size and discomfort. - Herpes simplex keratitis (ocular infection): controls viral replication and promotes corneal healing.

Aciclovir topical therapy is generally well tolerated, but local and systemic reactions can occur.

Common Side Effects: - Application site irritation: mild redness or discomfort at the site. - Burning sensation: transient feeling of warmth after application. - Itching: occasional pruritus around the treated area. - Dryness: skin may become slightly dry or flaky.

Serious or Rare Side Effects: - Allergic contact dermatitis: rash, swelling, or blistering. - Stevens‑Johnson syndrome: severe skin reaction requiring immediate medical attention. - Ocular toxicity: if applied to the eye in non‑ophthalmic form, may cause irritation or corneal damage. - Systemic hypersensitivity: rare anaphylactic reactions.

When using Lavirk, consider the following safety measures. - Pregnancy: consult a healthcare professional before use. - Breastfeeding: discuss potential risks with a physician. - Renal impairment: monitor for increased systemic absorption, especially with extensive application. - Lesion selection: apply only to confirmed herpes lesions; avoid healthy skin. - Ocular exposure: do not apply to the eye unless using an ophthalmic preparation. - Store at room temperature: keep in the original container, protect from moisture and direct heat.

Aciclovir topical has limited systemic interactions, but certain co‑administered agents may affect safety or efficacy.

Major Interactions (Avoid): - Probenecid: may increase systemic aciclovir levels if absorbed. - Nephrotoxic drugs: monitor renal function when extensive topical use is combined.

Moderate Interactions (Monitor Closely): - Topical corticosteroids: may reduce antiviral effectiveness. - Immunosuppressants: could delay lesion healing. - Other topical agents: may increase local irritation when used together.
