If a patient taking acyclovir has a prescription for theophylline, what should the nurse do?

• A. Continue without action.
• B. Contact the prescribing healthcare provider.
• C. Advise the patient to stop taking theophylline.
• D. Prescribe an alternative medication.

Answer: (B)

In situations where a patient is taking acyclovir and has a prescription for theophylline, it is essential for the nurse to contact the prescribing healthcare provider. This is due to the potential for a drug interaction between acyclovir and theophylline, which can affect the metabolism and clearance of theophylline, potentially leading to elevated levels of the drug in the body. Increased theophylline levels can result in toxicity, with symptoms such as increased heart rate, restlessness, and gastrointestinal disturbances. By contacting the healthcare provider, the nurse ensures that the treatment plan remains safe and effective for the patient. The provider can then assess the need for monitoring theophylline levels or consider adjusting the dosage or switching to an alternative medication if necessary. This proactive approach is crucial to preventing adverse effects and ensuring optimal patient care.
