HOW IT WORKS
Valtrex is an antiviral drug. It works by blocking the action of viral enzymes hence inhibiting their replication.

Valtrex is taken orally with or without food. It is recommended that you take lots of water after ingesting the tablet in order to reduce the chances of side effects.
Under no circumstance are you allowed to share your medicine with other people because valtrex is not suitable for everyone. It is only prescribed after a detailed medical history has been taken.
The dosage and length of taking the medication highly depends on the type of infection, its severity and your response to treatment. Make sure that you complete the dose and never skip the medication.
