Clinical Summary

A prodrug of acyclovir that is used in the treatment of HERPES ZOSTER and HERPES SIMPLEX VIRUS INFECTION of the skin and mucous membranes, including GENITAL HERPES.

Therapeutic Applications

Valacyclovir is used to treat infections caused by certain types of viruses. In children, it is used to treat cold sores around the mouth (caused by herpes simplex) and chickenpox (caused by varicella zoster).

This medication may also help reduce how long pain remains after the sores heal.

The statistics above track documented pharmaceutical treatment trends assigned to beneficiaries specifically under federal public programs. Evaluating the prescriptive footprints of clinical practitioners like DANIEL C. YAU MD provides transparency into local medical care patterns within Riverside, CA.

Key Learning Objectives for this Profile:

  • Prescribing Frequencies: Track and evaluate the volume metrics of specific brand-name and generic medical formulas chosen by this provider over time.
  • Clinical Focus Areas: Identify how the provider distributes therapeutic selections across medical care options to gain insight into their true day-to-day **Ophthalmology** practice concentrations.
  • Program Cost Awareness: Review the calculated total systemic drug costs and raw transactional volumes linked to these orders to better anticipate network insurance coverage structures.
  • Patient-Centered Evaluation: Cross-reference localized regional care comparisons to align practitioner habits directly with your proactive health maintenance goals.
