What happens when you take acyclovir with certain foods?

Acyclovir, an antiviral medication, is used to treat and prevent herpes infections, including genital herpes, cold sores, and shingles. However, it is essential to be aware of potential food interactions that may affect its efficacy or increase the risk of side effects.

While there are no severe or life-threatening food interactions with acyclovir [1], some foods may affect the absorption or metabolism of the drug.

How does alcohol impact acyclovir?

Consuming alcohol while taking acyclovir may not have any severe consequences, but it may increase the risk of side effects such as dizziness, drowsiness, or stomach upset. Moderate amounts of alcohol (up to two drinks per day for men and one drink per day for women) are generally considered safe.

Can you take antacids with acyclovir?

Yes, you can take antacids, such as Tums or Rolaids, with acyclovir. However, taking antacids containing aluminum or magnesium at the same time as acyclovir may decrease the absorption of the medication. To minimize this interaction, take antacids 2-3 hours apart from acyclovir [2].

Do certain foods reduce acyclovir efficacy?
