Tazzle 20 FM is a medication that contains tadalafil, the same active ingredient found in other erectile dysfunction (ED) treatments like Cialis. It is primarily used to help men with erectile dysfunction by improving blood flow to the penis, allowing for a firmer and longer-lasting erection when sexually stimulated. As with other ED medications, Tazzle 20 FM does not provide protection against sexually transmitted infections (STIs). It only helps with achieving and maintaining an erection and does not prevent the transmission of viruses or bacteria during sexual activity. Tazzle should not be used in combination with nitrates (medications for chest pain), as it can cause a dangerous drop in blood pressure. It is also important to inform your doctor about any existing health conditions, such as heart disease, liver or kidney issues, or if you are taking other medications.
