Mood changes on Viagra: what to expect
Mood changes — anxiety, low mood, irritability, emotional blunting — are an under-recognised but important side-effect category for many medications. Whether Viagra (Sildenafil Citrate) at 25mg, 50mg, 100mg causes mood changes depends on Sildenafil Citrate and the indication. This page focuses on the practical pattern, what is normal and what calls for review.
Documented mood effects of Viagra
For some medications in Erectile Dysfunction (ED), mood changes are part of the central indication. For others, mood changes are listed in the prescribing information for Sildenafil Citrate as side effects in a small subset of users, sometimes appearing in the first weeks of therapy and resolving spontaneously. During sexual stimulation, nitric oxide is released in the corpus cavernosum and activates an enzyme that produces cyclic GMP.
When mood changes need review
Mild irritability or transient low mood in the first weeks on Viagra at 25mg, 50mg, 100mg is common and often improves. Persistent low mood, new anxiety that interferes with daily life, suicidal thoughts, or any sudden severe mood change warrants prompt review with the prescriber. According to current guidelines, suicidal ideation while starting any new medication should be treated as urgent.
