Those who have a known allergy to sildenafil or any of the drug's inactive ingredients should not use Kamagra. It is strongly advised against using it concurrently with organic nitrates or nitric oxide donors because of the possibility of severe, potentially fatal hypotension. It is not recommended for patients to use Kamagra 100 mg if they have recently experienced severe cardiovascular events such as a myocardial infarction or stroke, significant liver impairment, or inherited retinal degenerative illnesses. Furthermore, because priapism-prone conditions like sickle cell anemia enhance the likelihood of long-lasting, painful erections, vigilance is necessary.
