Botulinum Toxin Injections -- Medical
Botulinum toxin is made from a type of bacteria. It is a toxin that affects nerves. An injection puts this toxin into muscle. There, it blocks the release of the chemical signal from the nerves to muscles. This will decrease the muscle contraction. Botulinum toxin is used for cosmetic and medical reasons. The injection process is often called botox injection, although any brand of the botulinum toxin may be used.
Call Your Doctor
Contact your doctor if any of the following occurs:
- Difficulty breathing
- Difficulty swallowing
- Difficulty speaking
- Severe lower eyelid droop or obstructed vision
- Excessive weakness around the injection site
- Rash or any other sign of an allergic reaction
In case of an emergency, call for medical help right away.

- Cervical dystonia—abnormal spasms of neck muscles
- Blepharospasm—spasm of eyelid muscles
- Chronic migraines
The injection has also been used to treat other conditions, such as:
- Tension headaches
—spasm of esophageal muscles causing difficulties in swallowing
- Spasmodic dysphonia
Muscle spasms due to
- Spasticity associated with multiple sclerosis
- Spasticity in leg and arm muscles due to brain injury/stroke

Complications are rare. When they occur, they are temporary and mild. Side effects are related to the site of injection. For example, if injections take place near the eyes, there may be complications with the eyelids or brow line.
Temporary issues may include:
- Stinging around the injection sites
The following are less common reactions. They are generally mild and do not last long.
Other complications that may occur include:
- Excessive weakness of the muscle around the eyes—can cause drooping of the eyelids or obstruction of vision
- Difficulty swallowing—can occur in patients receiving injections in their neck
- Compensatory hyperhidrosis—people being treated for hyperhidrosis may develop increased sweat production at another area of the body
- Excessive weakness or wasting in certain muscles—the injection may slow any improvement in the muscle
- Neck weakness in people with long, thin necks
Risk of the botulinum toxin spreading beyond the injection area—may cause botulism symptoms, including difficulty breathing and death in severe cases. Children with
may be at a higher risk for this side effect.
This procedure may worsen nerve or muscle disorders, such as:
- Amyotrophic lateral sclerosis
- Myasthenia gravis
- Amyotrophic lateral sclerosis
The toxin can also interact with medications such as antibiotics. Tell your doctor about all of the medications that you are taking.
You should not have botox if you:
- Have an infection or inflammation in the area where botox will be injected
- Are sensitive to the ingredients in botox
- Are pregnant or breastfeeding
