Individuals more likely to experience side effects from Kamagra 50 mg, which contains sildenafil, include those with certain pre-existing health conditions, such as heart disease, liver or kidney problems, and low blood pressure. People taking medications like nitrates or alpha-blockers, which can interact with sildenafil, are also at a higher risk of side effects. Older adults may experience more pronounced effects due to slower metabolism. Additionally, individuals who consume alcohol or have a history of eye conditions, like retinitis pigmentosa, may also face increased risk. It's crucial to consult a healthcare provider before using Kamagra to assess risks based on personal health.
