Detailed Answer:
Hi XXXX
Thanks for the query.
I understand your concern. & it's good that you acted promptly & enquired about it.
- Valacyclovir is an antiviral drugs & has good effect on herpes. At the same time it's known to have many grave side effects , one of them being blood in urine,more so in previous kidney problems.
- Also immunocompromised conditions/high blood pressure ( could be caused by herpes virus itself )/high cholesterol/diabetes/rheumatoid arthritis when accompanied by herpes, predispose the patient for blood in urine
* As blood in urine is a renal emergency,I would advise you to call your doctor & inform about blood in urine you have. & consult him right away for further investigations & management of the condition.

I hope the answer conveys you urgency of expert ( Urologist) consultation & management.PLease don't worry,early diagnosis & prompt treatment carries positive results.any further assistance you want, I would be happy to help.
