Viagra for people with diabetes: what to know
Diabetes is one of the most common chronic conditions worldwide and routinely co-exists with the indications Viagra (Sildenafil Citrate) is used for. Most people with well-managed diabetes can take Viagra at 25mg, 50mg, 100mg without difficulty, but a few practical points around blood glucose, autonomic symptoms and concomitant medications are worth covering.
Viagra and blood glucose
Sildenafil Citrate typically does not directly affect blood glucose, although individual Erectile Dysfunction (ED) agents have variable effects. Side effects such as nausea, dizziness or sweating can mimic hypoglycaemia and confuse the picture, particularly in insulin-treated patients. During sexual stimulation, nitric oxide is released in the corpus cavernosum and activates an enzyme that produces cyclic GMP.
Practical guidance
According to the prescribing information for Sildenafil Citrate, people with diabetes can usually start Viagra at the standard 25mg, 50mg, 100mg 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.
