Botox is a neurotoxin that affects nerves and causes muscle weakening. When injected into specific muscles, it blocks nerve signals to those muscles, preventing them from contracting or tensing up. This effect is temporary but can last for several months. Botox injections are often used for cosmetic purposes to smooth wrinkles on the face, but they are also used to treat a wide range of medical conditions, including:

• Neck spasms: In this painful condition, the neck muscles contract in an uncontrolled way, causing the head to twist or turn into an uncomfortable position.

• Excessive sweating or hyperhidrosis: Botox injections can be used to treat this condition, in which people sweat a lot even when theyre not hot or working up a sweat.

• Migraine: Botox injections may help reduce how often you get a migraine. This treatment is used mainly for people who have headaches 15 or more days a month.

• Eye movement disorders, such as a lazy eye (also called strabismus) .

• Cervical dystonia: An uncomfortable muscle spasm that causes the head and neck to twist or turn.

Botox injections are given in a doctors office and are mixed with saline (salt water) before being injected into the muscle with a tiny needle. The number of injections depends on the condition being treated and the size of the area being treated. The effects of Botox injections last about three to four months on average, after which retreatment is recommended.

It is important to note that Botox is made from the same toxin that causes a type of food poisoning called botulism. However, the forms of purified botulinum toxin used by licensed healthcare providers meet medical control standards and are safe when used properly. Some side effects of Botox injections include soreness at the injection site, headache, and muscle weakness. In rare cases, serious side effects such as difficulty breathing, irregular heartbeat, and loss of bladder control can occur.
