Super Kamagra you mean the commonly marketed combination of sildenafil + dapoxetine, there are several important combinations to avoid. Nitrates such as nitroglycerin or isosorbide — do not combine; sildenafil can cause a dangerous fall in blood pressure. Other ED medicines/PDE-5 inhibitors such as sildenafil (Suhagra, Penegra, Manforce, Fildena), tadalafil (Tadfil, Tadalis, Tazzle), or vardenafil — don't combine them because blood-pressure-lowering effects can add together. Antidepressants and other serotonergic medicines — important because of the dapoxetine component and potential serotonin-related reactions. MAO inhibitors — should not be combined with dapoxetine. Alpha-blockers (for example, tamsulosin/doxazosin) and some BP medicines require medical supervision because blood pressure can fall. Strong CYP3A4 inhibitors such as ritonavir, ketoconazole, or itraconazole can increase sildenafil exposure and side effects. Heavy alcohol use can increase dizziness and fainting risk, particularly with dapoxetine. Given that you've asked about several ED medicines, don't stack Super Kamagra with any of the sildenafil or tadalafil products you've mentioned.
