When taking generic Kamagra tablets, a patient should not take Nitroglycerin, Isosorbide Dinitrate, any nitric oxide donor medications, Cimetidine, Erythromycin, Azole or other antifungal drugs, Mibefradil, Rifamycins, or any medication used to treat hypertension. Taking any of these medications along with generic Kamagra tablets can have serious adverse effects. Furthermore, a local doctor should be alerted to any and all medications a patient is taking and to any existing medical conditions. Even if conditions are no longer present or are under control, it is important for a local doctor to know about all of them. In some cases, a patient may either not be able to take these tablets or will need to have the dosage altered to suit personal health needs.
