- Facial flushing: Sudden warmth and redness, lasts 30-90 minutes
- Nasal congestion: PDE5 inhibition in sinus tissues
Common (1 in 10 to 1 in 100)
- Dyspepsia: Acid reflux from esophageal sphincter relaxation
- Visual disturbances: Mild blue tint (sildenafil's retinal PDE6 effect)
- Dizziness: Blood pressure dip upon standing suddenly
Uncommon but Significant (1 in 100 to 1 in 1,000)

When to Seek Immediate Help
Stop use and call a doctor for:

Long-Term Use Considerations
With ongoing Fildena 100mg use:
- Tolerance develops to flushing/headaches
