Description
Description
Acyclovir 250mg Injection, a synthetic nucleoside analog, primarily targets and inhibits the replication of herpes simplex virus (HSV) and varicella-zoster virus (VZV). It achieves this by selectively interfering with viral DNA polymerase, an enzyme crucial for viral DNA replication. Acyclovir is activated within virus-infected cells, where it is converted into acyclovir triphosphate, which competitively inhibits viral DNA polymerase and competitively blocks the incorporation of deoxyguanosine triphosphate into growing viral DNA chains, ultimately leading to the inhibition of viral DNA synthesis without affecting normal cellular processes. This mechanism effectively halts the spread of the virus within the body.

Precautions & Warnings
Following are the precautions and warnings for Acyclovir 250mg Injection:
This medication should be used with caution in patients with pre-existing kidney conditions, as it is primarily eliminated through the kidneys. Regular monitoring of kidney function is advised.
Acyclovir should be administered with care in patients with a history of neurological disorders, as it may cause neurological side effects like confusion and hallucinations.
Elderly patients may be more susceptible to adverse effects; dosage adjustments might be necessary.
Patients with a compromised immune system should be closely monitored for the development of resistant viral strains and other opportunistic infections.
Caution is advised in patients with a history of electrolyte imbalances, especially those with kidney impairment, as acyclovir can affect electrolyte levels.
It is important to maintain adequate hydration during treatment to reduce the risk of kidney damage.
Acyclovir should be discontinued if signs of a severe allergic reaction occur, such as a rash, hives, or difficulty breathing.
This medication should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Drug Interactions
Following are the drug interactions for Acyclovir 250mg Injection:
Probenecid can decrease the renal excretion of acyclovir, leading to increased acyclovir blood levels.
Concomitant use with other nephrotoxic drugs (e.g., aminoglycosides, amphotericin B) may increase the risk of kidney-related side effects.
Acyclovir may decrease the effectiveness of mycophenolate mofetil by inhibiting its metabolism.
Theophylline levels may be increased when used with acyclovir, potentially requiring dose adjustments.
Acyclovir can interact with other antiviral drugs like zidovudine, possibly increasing the risk of hematologic adverse effects.
Acyclovir may decrease the immune response to live vaccines, such as measles, mumps, and rubella.
Some antiretroviral medications, like zidovudine, may have decreased effectiveness when combined with Acyclovir.
Food Interactions
Following are the food interactions for Acyclovir 250mg Injection:
Avoid excessive alcohol consumption during treatment as it may increase the risk of liver problems and affect the effectiveness of the medication.
Maintain adequate hydration by drinking plenty of fluids, especially water, to support kidney function and prevent dehydration.
Avoid grapefruit and grapefruit juice as they can interfere with the metabolism of Acyclovir, potentially leading to increased drug levels and side effects.
There is no specific food restriction, but a balanced diet is recommended to support overall health and recovery during treatment.
Avoid high-fat meals as they may affect the absorption of Acyclovir, and it is best to take the medication on an empty stomach for optimal absorption.
Consult your healthcare provider if you have any specific dietary concerns or restrictions to ensure a personalized approach to your treatment.
Avoid dairy products if you are lactose intolerant, as some formulations may contain lactose, and discuss alternative options with your pharmacist.
