Aspadol 100mg is a medication that contains the active ingredient Tapentadol. It is primarily used to treat moderate to severe pain, such as pain caused by surgery or injury. Aspadol works by blocking the transmission of pain signals in the brain and nervous system. However, Aspadol is a potent narcotic pain reliever that can be habit-forming and may cause side effects such as dizziness, drowsiness, constipation, and nausea. It should only be used under the guidance of a healthcare professional and should not be shared with others.
