Filitra should not be used in individuals who are taking nitrate medications (commonly prescribed for chest pain) or have certain health conditions, such as severe heart or liver problems. It is also not approved for use in women or individuals under 18 years of age. Before starting treatment, consult with a healthcare provider to ensure it is safe based on your medical history and current medications. If Filitra is unavailable or unsuitable, other medications containing vardenafil, such as Levitra or other generic versions, offer similar efficacy and can be considered as alternatives. https://www.genericday.com/filitra-20-mg.html
