Ciafill contains tadalafil as its active ingredient. Other medications that are prescribed for ED could contain either vardenafil or sildenafil. While all these medications work in a similar manner (by increasing the blood flow to your penis), the main difference is in the active ingredients and the duration that they stay active for in your body.
While medications like Ciafill and Efil can have their effects in your body for 36 hours, others like Viagra and Manforce only stay active for up to four hours. That means that when you take Ciafill or Efil, you will be able to achieve erections for a couple of days from just one dose, whereas you will need to take multiple doses of Viagra to get the same result.
