Tadaga 5 mg, containing Tadalafil, should be avoided by individuals with certain medical conditions or who are taking specific medications. People with severe heart or liver problems, recent history of stroke or heart attack, low blood pressure, or hereditary eye disorders like retinitis pigmentosa should not use Tadaga. It is also contraindicated for those taking nitrates or alpha-blockers, as combining these can lead to dangerous drops in blood pressure.

Always consult a doctor before use to ensure it's safe based on your health profile.
