Botulinum toxin is a purified substance that's derived from bacteria. Injections of botulinum toxin block the nerve signals to the muscle in which it was injected. Without a signal, the muscle is not able to contract. The end result is diminished unwanted facial wrinkles or appearance. Commonly known types of botulinum toxin type A injections include Botox®, Dysport® and Xeomin®.
Why Botox works isn’t completely clear. There’s some evidence that it may reduce the production of neurotransmitters related to pain in the areas where it’s injected. There’s also some evidence that it may have a broader effect on the brain’s pain centers, reducing the sensitivity that causes migraine sufferers to react to migraine triggers. While the exact mechanisms are poorly understood, the studies, as well as many of my patients’ experiences, do show a real benefit for many people.
Study responders were defined as patients who showed at least a 2-grade improvement from baseline value on the HDSS 4 weeks after both of the first two treatment sessions or had a sustained response after their first treatment session and did not receive re-treatment during the study. Spontaneous resting axillary sweat production was assessed by weighing a filter paper held in the axilla ov er a period of 5 minutes (gravimetric measurement). Sweat production responders were those patients who demonstrated a reduction in axillary sweating from baseline of at least 50% at week 4.

Botox comes as a crystalline substance from the manufacturer, which then has to be reconstituted with saline or another liquid. Practitioners add varying amounts of liquid when reconstituting it. Although there is no right or wrong amount of liquid to add, most physicians add about 2 mL-3 mL (about a half a teaspoon) of liquid to each vial. Some add quite a bit more, which can lead patients to think they are getting more Botox when, in reality, they are getting the same or less amount of Botox than samples reconstituted in a stronger way. It is the total dose of medication, not the volume of liquid, that leads to the desired effect.
Botox Cosmetic is FDA-approved and injections are relatively safe when performed by an experienced injector. It has proven to be a successful and valuable therapeutic protein when dosage, frequency of treatment & variety of treated clinical conditions are considered. The best way to ensure you receive the results you are looking for is to only receive injections from a highly experienced provider, such as the medical and nursing professionals at Ideal Image.
Botulinum toxin injections are one approach to the treatment of muscle spasticity. These injections can be given with ease and have minimal side effects. They can also be used in very focal spasticity problems that involve a few muscle groups. This treatment may not be right for some patients, such as patients with severe, widespread muscle spasticity, and patients with permanent muscle contractures that have become rigid.
Three percent of patients experienced eyelid drooping in the frown lines studies, one percent of patients experienced eyelid swelling in the crow's feet studies, and one percent of patients experienced brow drooping in the forehead lines studies. Other possible side effects include: dry mouth; discomfort or pain at the injection site; tiredness; headache; neck pain; eye problems: double vision, blurred vision, decreased eyesight and dry eyes; and allergic reactions. These are not all of the possible serious side effects of BOTOX® Cosmetic. Please see the Important Safety Information including Boxed Warning and Medication Guide and talk to your specialist.
Serious adverse reactions, including excessive weakness, dysphagia, and aspiration pneumonia, with some adverse reactions associated with fatal outcomes, have been reported in patients who received BOTOX® injections for unapproved uses. In these cases, the adverse reactions were not necessarily related to distant spread of toxin, but may have resulted from the administration of BOTOX® to the site of injection and/or adjacent structures. In several of the cases, patients had pre-existing dysphagia or other significant disabilities. There is insufficient information to identify factors associated with an increased risk for adverse reactions associated with the unapproved uses of BOTOX®. The safety and effectiveness of BOTOX® for unapproved uses have not been established.
Cornea problems have been reported. Cornea (surface of the eye) problems have been reported in some people receiving BOTOX® for their blepharospasm, especially in people with certain nerve disorders. BOTOX® may cause the eyelids to blink less, which could lead to the surface of the eye being exposed to air more than is usual. Tell your doctor if you experience any problems with your eyes while receiving BOTOX®. Your doctor may treat your eyes with drops, ointments, contact lenses, or with an eye patch.
