Like any medication, sildenafil can potentially cause side effects, although not everyone experiences them. Some common side effects of sildenafil include:
Headache: This is one of the most common side effects reported by people taking sildenafil.
Flushing: Some people may experience redness or warmth in the face, neck, or chest.
Indigestion or upset stomach: Sildenafil can sometimes cause gastrointestinal discomfort, such as stomach pain or acid reflux.
Nasal congestion: It may cause a stuffy or runny nose.
Dizziness or lightheadedness: Some individuals may feel dizzy or faint shortly after taking sildenafil.
Vision changes: Sildenafil can temporarily affect vision, causing blurred vision, changes in color vision, or increased sensitivity to light.
Muscle pain: Some people may experience muscle aches or back pain.
Priapism: This is a rare but serious side effect characterized by a painful and prolonged erection lasting more than four hours. If this occurs, immediate medical attention is necessary to prevent tissue damage to the penis Hearing loss: In rare cases, sildenafil may cause sudden hearing loss or ringing in the ears (tinnitus). Allergic reactions: Although uncommon, some individuals may experience allergic reactions to sildenafil, which can manifest as rash, itching, swelling (particularly of the face, tongue, or throat), severe dizziness, or trouble breathing
