Valtrex for people with diabetes: what to know
Diabetes is one of the most common chronic conditions worldwide and routinely co-exists with the indications Valtrex (Valacyclovir) is used for. Most people with well-managed diabetes can take Valtrex at 500mg, 1000mg without difficulty, but a few practical points around blood glucose, autonomic symptoms and concomitant medications are worth covering.
Valtrex and blood glucose
Valacyclovir typically does not directly affect blood glucose, although individual Antiviral Medications agents have variable effects. Side effects such as nausea, dizziness or sweating can mimic hypoglycaemia and confuse the picture, particularly in insulin-treated patients. Valacyclovir is rapidly and almost completely converted to acyclovir during first-pass intestinal and hepatic metabolism by valacyclovir hydrolase.
Practical guidance
According to the prescribing information for Valacyclovir, people with diabetes can usually start Valtrex at the standard 500mg, 1000mg dose. Monitoring blood glucose more frequently in the first weeks is sensible. Diabetic complications such as autonomic neuropathy or significant cardiovascular disease may shift the risk-benefit balance and require specialist input.
