Botox injections are used to treat conditions such as strabismus and eyelid spasms. They can also be used to reduce migraines and excessive sweating.

Injections are usually performed in a doctor’s office. The process involves injecting tiny amounts of botulinum toxin into the muscle. This substance works by blocking acetylcholine, a neurotransmitter. It also disrupts nerve signaling processes, which can result in muscle paralysis.

Depending on the condition being treated, the number of Botox injections needed may vary. For example, people with cervical dystonia will need multiple injections, while others will only need to have a few.

Several studies have shown that Botox is safe in the right therapeutic setting. However, there are certain risks, including bruising, swelling, and allergic reactions. You should talk to your healthcare provider before undergoing any procedure.

How to Prepare for a Botox Appointment

Some individuals will experience minor side effects such as headaches, dry eyes, and bruising. These symptoms can last as little as a day or as long as a month. If they do not go away after a day, consult your physician.

Botox is most commonly injected to reduce the appearance of wrinkles and to prevent overactive sweating. The effects are temporary and will usually last between three and six months.

To reduce the chance of side effects, you should avoid rubbing the area where the injection has been made for at least 24 hours. Massaging the area can spread the injected substance and cause it to move to an unintended muscle.
