This is because the discretionary procedures tend to be out of pocket, and providers are used to answering the question: how much does it cost? An MRI, on the other hand, might have several prices: A sticker price, a negotiated or reimbursed rate (what the insurance company pays), the rate that Medicare and Medicaid pay for treatments for people who are older and those who have low income, an out-of-network price, and so on. We know about this because we’ve done pricing surveys for about 35 common procedures in seven U.S. metro areas, collecting cash or self-pay prices for both medically necessary procedures (an MRI, a colonoscopy) and discretionary procedures (Botox, Lasik).
In rare cases, Botox toxin can spread to areas beyond the injection site. If this happens, you may experience muscle weakness, vision changes, difficulty swallowing, and drooping eyelids. To reduce your risk of serious side effects and complications, always make sure Botox is prescribed and administered by a trained healthcare professional who has experience in using Botox.
But today it's the medical uses of the drug that are the great moneymaker, in part because doctors are getting a better handle on how to use it. Botulinum toxin type A is one of seven neurotoxins produced from Clostridium botulinum. Contracting botulism is bad news: it can cause blurred vision, persistent trouble swallowing and worse. In one recent case, close to 30 people were hospitalized in Ohio in 2015 after attending a church potluck. One person died. The outbreak was ultimately attributed to a potato salad made from improperly home-canned potatoes that were harboring the bacteria. Given its level of toxicity, some countries have even explored its potential use as a bioweapon.
As with all therapeutic proteins, there is a potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibo dy) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to onabotulinumtoxinA in the studies described below with the incidence of antibodies in other studies or to other products may be misleading.
