ACLOV 200MG

# Acyclovir 200 mg ## Short Description **Acyclovir 200 mg** is an antiviral medicine used to treat infections caused by **herpes viruses**, including herpes simplex virus (HSV). It is commonly prescribed for **genital herpes, herpes labialis (cold sores), and certain recurrent herpes simplex infections**. It may also be used in selected cases of **chickenpox or shingles**, depending on the patient's age, condition, and treatment guidelines. Acyclovir works by interfering with viral DNA replication, helping reduce the growth and spread of the virus. > **Important:** Acyclovir does not permanently eliminate herpes viruses from the body. Starting treatment early, when prescribed, can provide the greatest benefit. --- ## Key Benefits * Helps treat **herpes simplex virus (HSV) infections** * May reduce the duration and severity of herpes outbreaks * Helps reduce the formation of new herpes lesions * Can help promote faster healing of existing lesions * May reduce pain and discomfort associated with herpes outbreaks * Can be used for certain recurrent herpes infections * May be prescribed for prevention of recurrent herpes in selected patients --- ## Uses / Indications ### **Genital Herpes** Acyclovir may be prescribed to treat episodes of **genital herpes caused by HSV**, including initial and recurrent outbreaks. It may also be used as suppressive therapy in people with frequent recurrences. ### **Cold Sores / Herpes Labialis** Acyclovir can be used for certain herpes simplex infections affecting the lips and mouth. ### **Herpes Simplex Infections** It may be prescribed for HSV infections involving the skin and mucous membranes, particularly in patients with weakened immune systems. ### **Chickenpox** Acyclovir may be prescribed for chickenpox in selected patients, particularly when treatment is started early and when the patient is at increased risk of complications. ### **Shingles** Higher doses of acyclovir are generally used for herpes zoster (shingles). A **200 mg tablet is not necessarily the appropriate dose for shingles**, so patients should follow the specific prescription. --- ## How It Works Acyclovir is a **nucleoside analogue antiviral medicine**. After entering an infected cell, acyclovir is converted into its active form, acyclovir triphosphate. The active medicine interferes with the viral enzyme **DNA polymerase** and can terminate viral DNA chain growth. **Acyclovir → activated in infected cells → inhibits viral DNA polymerase → interrupts viral DNA replication → slows viral multiplication** Acyclovir has greater activity in infected cells because viral thymidine kinase helps activate the medicine. It does **not remove latent herpes virus from nerve cells**, so herpes infections can recur. --- ## Dosage & Administration > **Important:** The appropriate dose depends on the type of herpes infection, whether the infection is an initial or recurrent episode, kidney function, age, immune status, and the specific product. The following information is general and does not replace a prescription. ### Genital Herpes For certain adult genital herpes infections, acyclovir may be prescribed in divided doses several times daily. The exact regimen varies for: * Initial episodes * Recurrent episodes * Suppressive treatment ### Herpes Simplex Prevention Patients with frequent recurrent herpes infections may be prescribed a lower maintenance regimen for suppression. ### Chickenpox and Shingles These conditions generally require **different and higher dosing schedules** than a 200 mg regimen. Do not use the 200 mg strength for chickenpox or shingles unless it has specifically been prescribed. ### How to Take Acyclovir * Take exactly as prescribed. * Swallow tablets with water. * Acyclovir may generally be taken **with or without food**. * Maintain adequate fluid intake unless your healthcare professional has advised fluid restriction. * Start treatment as soon as possible after symptoms appear when prescribed for an outbreak. ### Kidney Impairment Acyclovir is eliminated mainly through the kidneys. Patients with reduced kidney function may require **dose adjustment**. ### Missed Dose Take the missed dose when remembered unless it is nearly time for your next scheduled dose. **Do not take two doses together.** --- ## Side Effects ### Common Side Effects Possible side effects include: * Nausea * Vomiting * Diarrhea * Headache * Abdominal discomfort * Fatigue ### Less Common Effects Some patients may experience: * Dizziness * Skin rash * Itching * Increased sensitivity to light * Temporary changes in laboratory kidney tests ### Serious Side Effects Seek urgent medical attention for: * Severe allergic reaction * Swelling of the face, lips, tongue, or throat * Difficulty breathing * Severe confusion * Hallucinations * Seizures * Severe weakness * Significant reduction in urine output Neurological side effects are more likely in people with **kidney impairment or excessive drug exposure**. --- ## Precautions & Warnings ### Kidney Function Acyclovir is primarily eliminated by the kidneys. Patients with: * Chronic kidney disease * Dehydration * Older age * Reduced kidney function may have an increased risk of acyclovir accumulation and toxicity. ### Maintain Adequate Hydration Drink sufficient fluids during treatment unless your doctor has instructed you to restrict fluids. Adequate hydration can help reduce the risk of kidney-related complications. ### Weakened Immune System Patients with a weakened immune system may require different dosing and closer monitoring. ### Neurological Effects Confusion, hallucinations, tremors, or seizures can rarely occur, particularly in patients with kidney impairment. Seek medical advice if unusual neurological symptoms develop. ### Pregnancy Tell your healthcare professional if you are pregnant or planning pregnancy. Acyclovir may be used during pregnancy when clinically indicated, but treatment decisions should be individualized. ### Breastfeeding Acyclovir passes into breast milk in small amounts. Discuss its use with your healthcare professional if you are breastfeeding. ### Herpes Transmission Acyclovir reduces viral replication and can shorten outbreaks but **does not completely eliminate the risk of transmitting herpes**. For genital herpes: * Avoid sexual contact during active lesions. * Use condoms or other barrier protection where appropriate. * Follow your healthcare professional's advice regarding transmission prevention. --- ## Drug Interactions Acyclovir has relatively few major drug interactions, but certain combinations require caution. ### Probenecid Probenecid may reduce the elimination of acyclovir and increase acyclovir exposure. ### Nephrotoxic Medicines Combining acyclovir with medicines that can affect kidney function may increase the risk of renal toxicity. Examples may include certain: * NSAIDs * Aminoglycoside antibiotics * Immunosuppressive medicines * Other potentially nephrotoxic drugs ### Other Antivirals Tell your doctor if you are taking other antiviral medicines so potential duplication or interactions can be assessed. ### Mycophenolate Acyclovir may interact with **mycophenolate mofetil**, potentially affecting exposure to acyclovir and mycophenolic acid. Medical monitoring may be appropriate. Always tell your doctor or pharmacist about all prescription medicines, over-the-counter medicines, vitamins, and herbal supplements you take. --- ## Storage Information * Store according to the manufacturer's recommended temperature. * Keep tablets in the original packaging. * Protect from excessive heat and moisture. * Keep away from direct sunlight. * Keep out of reach and sight of children. * Do not use after the expiry date. * Do not use tablets from damaged or tampered packaging. --- ## Prescription Status **Acyclovir 200 mg is generally a prescription medicine**, although regulatory status can vary by country and formulation.
