What should I do if I substituted my prescribed Megalis 10mg with Forzest 20mg (Tadalafil 20mg) and am now experiencing ongoing severe headaches, body aches, eye pain, stomach upset, neck pain, body-wide nerve tightness, and extreme tiredness after taking one full pill followed by a half pill?
By taking one and a half tablets of Forzest 20mg, you took a total of 30mg of tadalafil, which is higher than your prescribed 10mg Megalis. What you are experiencing are common side effects of this larger dose. Since tadalafil can stay in your system for up to 36 hours, these symptoms should gradually fade as the drug clears. For now, please rest, stay well-hydrated, and avoid taking any more doses. If your symptoms worsen, or if you experience chest pain, dizziness, or vision changes, please seek medical evaluation right away.
