Risk factors for developing acyclovir-induced kidney problems include hypovolemia (abnormal decrease in the volume of blood usually due to dehydration), rapid IV infusion, too high a dose of acyclovir in relation to kidney function, and simultaneous use of other drugs toxic to the kidney. Kidney toxicity has been found to occur in approximately 12% to 48% of the cases involving IV administration. The incidence of kidney damage from oral dosing of acyclovir is less clear.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Dosage adjustment is recommended when giving acyclovir to patients with kidney impairment or who are also on other medicines that may be toxic to the kidney since this may increase the risk of kidney dysfunction, particularly when using IV acyclovir.\u00a0<\/span><\/p>\n<h2 id=\"how-long-do-side-effects-last\"><span style=\"font-weight: 400;\">How long do acyclovir side effects last?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Most side effects of acyclovir that occur usually do not need medical attention.

You should report any overdose situation to your healthcare professional.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Overdosage has been reported following inappropriately high doses given to patients by IV infusion whose fluid and electrolyte balance were not properly monitored. This has resulted in elevated blood urea nitrogen (BUN) and <\/span><span style=\"font-weight: 400;\">serum creatinine levels<\/span><span style=\"font-weight: 400;\"> causing kidney failure. Lethargy, convulsions, and coma have been reported. Overdose patients may require hemodialysis until kidney function is restored.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Overdose events using acyclovir cream topically are unlikely because there is very little absorption into the bloodstream.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Pregnancy and breastfeeding<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">There are no adequate and well-controlled clinical studies in pregnant women. Use acyclovir during pregnancy only if the potential benefit outweighs the risk. This drug has been found in breast milk following oral administration.
