Ocuvir 200 DT Tablet contains Acyclovir 200 mg, an antiviral agent primarily indicated for the treatment of herpes simplex virus infections, including orolabial herpes, genital herpes, and herpes zoster (shingles). Acyclovir functions by inhibiting viral DNA synthesis, thereby preventing viral replication and reducing the severity and duration of outbreaks. Ocuvir 200 DT is formulated as a dispersible tablet, allowing for ease of administration and rapid absorption. It is commonly prescribed for both initial and recurrent episodes of herpes infections, as well as for prophylactic use in immunocompromised patients to prevent viral reactivation. The medication is generally well-tolerated, with common adverse effects including headache, nausea, and gastrointestinal discomfort. Dosage and duration of therapy should be tailored according to the type and severity of infection, patient age, and renal function. Caution is advised in patients with renal impairment, and adequate hydration is recommended to prevent nephrotoxicity. Ocuvir 200 DT should be used under medical supervision, and patients are advised to complete the full course of therapy to ensure optimal therapeutic outcomes and minimize the risk of resistance development. It is contraindicated in individuals with known hypersensitivity to acyclovir or related compounds.
