See the DrugPatentWatch profile for acyclovir

Acyclovir is a commonly prescribed antiviral medication used to treat and prevent herpes simplex virus (HSV) and varicella-zoster virus (VZV) infections, including cold sores, genital herpes, and shingles [1]. According to the available information, there is no definitive evidence to suggest that long-term acyclovir use directly leads to organ damage [2].

However, it is important to note that, like all medications, acyclovir can have side effects, especially when used for extended periods or at high doses [3]. These side effects may include kidney damage, mainly in patients with pre-existing kidney problems or dehydration [3]. Additionally, there have been rare cases of neurological side effects, such as confusion, hallucinations, and seizures, associated with acyclovir use [3].

Patients should discuss any concerns about acyclovir use and potential side effects with their healthcare provider [2]. Regular monitoring of kidney function and adherence to the recommended dosage can help minimize the risk of complications [3].

In summary, while long-term acyclovir use may be associated with side effects such as kidney damage, there is no clear evidence directly linking the medication to organ damage over time [1][2][3]. Patients should consult their healthcare providers to ensure proper usage and monitoring while taking acyclovir.
