Interactions between Acyclovir and Other Medications

Acyclovir is an antiviral medication commonly used to treat herpes simplex virus infections. While generally considered safe, interactions with other medications can occur. It's essential to consult your doctor or pharmacist before taking any over-the-counter (OTC) medications with acyclovir.

Medications to Avoid or Use with Caution

1. Probenecid [1]: This medication, used to treat gout, can increase the levels of acyclovir in the body, potentially leading to increased risk of side effects.
2. Zidovudine [2]: Another antiviral medication, zidovudine can increase the risk of side effects when taken with acyclovir.
3. Phenytoin [3]: This antiepileptic medication can decrease the effectiveness of acyclovir.
4. Fosphenytoin [3]: Similar to phenytoin, fosphenytoin can also decrease the effectiveness of acyclovir.

Over-the-Counter Medications to Use with Caution

While not necessarily contraindicated, the following OTC medications may interact with acyclovir:

1. Pain relievers: Aspirin, ibuprofen, or acetaminophen may increase the risk of stomach upset or bleeding when taken with acyclovir.
2. Cough and cold medications: Decongestants, antihistamines, or cough suppressants may interact with acyclovir or exacerbate side effects.
