Botox is a brand name of a toxin made by the bacterium Clostridium botulinum. The most common reason doctors use Botox is to reduce the appearance of facial wrinkles. But getting a Botox shot can help treat other conditions, such as: Severe underarm sweating (hyperhidrosis) Cervical dystonia, a neurological disorder that causes severe neck and shoulder muscle spasms Blinking that you can’t control (blepharospasm) How to Use: The provider uses a small needle to inject Botox into specific muscles with only minor discomfort. It generally takes 7 to 14 days to take full effect. It’s best to avoid alcohol starting at least 1 week before the procedure. You should also stop taking aspirin and anti-inflammatory medications 2 weeks before treatment to help prevent bruising.
