Tazzle 10 FM is usually taken about 30–60 minutes before sexual activity, and its effect can last up to 36 hours (much longer than sildenafil‑based tablets). The strip is placed on or under the tongue, where it dissolves quickly and is absorbed through the mouth lining; it should not be swallowed whole or handled with wet hands. It should not be taken more than once a day and must be used only as prescribed by a doctor, especially if you have heart, liver, kidney, or blood‑pressure issues. https://www.genericday.com/tazzle-10-fm.html
