Aciclovir can interact with other medications, including certain vaccines and medications that affect kidney function. Inform your healthcare provider about all medications and supplements you are taking to avoid potential interactions.
Are there any precautions I should take while using aciclovir?
Avoid touching your eyes or mucous membranes after applying the cream to prevent spreading the virus. Stay hydrated, especially if taking oral aciclovir, as it can affect kidney function. If you have kidney issues or a weakened immune system, consult your doctor before use.
What should I do if I miss a dose?
For oral aciclovir, take the missed dose as soon as you remember. If it’s almost time for your next dose, skip the missed dose and resume your regular schedule. Do not double up on doses.
How should I store aciclovir?
Store aciclovir cream at room temperature, away from moisture and heat. Oral tablets should be kept in a cool, dry place. Keep all medications out of reach of children and do not use them past their expiration date.
