Frequently Asked Questions

Can I take a higher dose of Darunavir if my symptoms don't improve?

No. Never increase the dose of Darunavir without medical advice. If your current dose is insufficient, contact your healthcare provider to discuss a dose adjustment or alternative treatment.

Can antivirals cure herpes?

No. Antivirals such as acyclovir and valacyclovir suppress herpes virus replication and reduce outbreak severity and frequency, but the virus remains latent in nerve cells for life. Treatment does not eliminate the virus.
