Botulinum toxin, or Botox, is a protein that stops muscle spasms. It is injected directly into the muscle. A spasm occurs when the muscle contracts or moves on its own.
Botox injectionsare usually done in the doctor's office.
The doctor uses a fine needle to inject small amounts of botulinum toxin into the skin or muscles. The number of injections needed depends on many factors, including the extent of the area being treated.
Botoxblocks nerve signals to the muscles. As a result, the injected muscles cannot contract (tighten).
These effects are always temporary, but can last several months. The muscle injected depends on the main area of concern. Several areas can be treated in one session. If you have any problems breathing, swallowing or talking after receiving Botox injections, call your doctor right away.
In practice, doctors often use an intradermal injection for this purpose, since they consider that there is a lower risk of adverse effects compared to intramuscular injection. The total recommended dose for spasticity is divided into multiple injections into the affected muscles. For HAV and urinary incontinence caused by a neurological condition, Botox is given by intradetrusor injection. That's highly unlikely, but it's a more than compelling reason not to go bargain hunting for Botox.
Botox binds irreversibly to receptors on presynaptic nerve terminals and is absorbed at the nerve terminal. However, side effects such as ptosis of the eyebrows, heaviness of the eyebrows and difficulty performing facial expressions were more prominent on the side of the IM injection. In one study, 25 of 27 people who used Botox improved their condition within 48 hours after receiving the drug. However, some cases of hair loss have been reported since Botox was approved for use and became available on the market.
In some cases, it will be recommended to use weekly casts of a joint for several weeks (serial plaster) after giving the injections. It is possible that these clinical differences are due to disparity in the initial severity of wrinkles, not to injection techniques. To treat this type of urinary incontinence, Botox is injected directly into the detrusor muscle of the bladder. Botox contains onabotulinumtoxinA, which is a complex that contains botulinum toxin type A in addition to other proteins.
In this pilot study, the anti-wrinkle effect of BTXA was not significantly different between the IM injection and the ID injection for the three participants. A previous split-face study concluded that there are no beneficial effects of ID BTXA compared to normal saline injection.2 If you choose botulinum toxin injections, you will need to undergo treatment every three to six months to maintain optimal results.
