An injection of rimabotulinumtoxinB may cause symptoms of botulism, such as severe or life-threatening difficulty breathing or swallowing, to spread from the injection site. People who experience swallowing problems while using this drug may continue to experience them for several months. To prevent food or liquid from entering their lungs, they might need to be fed through a feeding tube. RimabotulinumtoxinB injections might cause symptoms to appear right away or up to several weeks later. People of any age receiving treatment for any ailment may experience symptoms, but youngsters receiving treatment for spasticity probably run the largest risk (muscle stiffness and tightness). Inform your doctor if you have or have ever had any breathing or swallowing issues, such as asthma or emphysema, or any conditions that affect your muscles or nerves, such as amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig’s disease; condition in which the nerves that control muscle movement slowly die, resulting in the muscles shrinking and weakening), motor neuropathy (condition in which the muscles weaken over time), or myasthenia grav (condition that causes muscle weakness that may improve with activity). Call your doctor right away if you have any of the following symptoms: the inability to control urination, loss of strength or muscle weakness throughout the body, double or blurred vision, drooping eyelids, difficulty breathing, speaking, or eating.

As soon as you start receiving rimabotulinumtoxinB injections for therapy and after each injection, your doctor will give you the medication guide provided by the manufacturer. If you have any questions after reading the material, see your doctor or pharmacist. For more information about the Medication Guide, go to the Food and Drug Administration (FDA) website or the manufacturer’s website.

Why is this medication prescribed?

Injections of rimabotulinumtoxinB are used to treat cervical dystonia symptoms (spasmodic torticollis; uncontrollable tightening of the neck muscles that may cause neck pain and abnormal head positions). Additionally, chronic sialorrhea is treated by rimabotulinumtoxinB injection (ongoing drooling or excessive salivation). A group of drugs known as neurotoxins includes ribabotulinumtoxinB injection. RimabotulinumtoxinB injection functions by obstructing the nerve signals that result in the muscles’ uncontrolled tightness and movement. By inhibiting the nerve signals that lead to excessive salivation, rimabotulinumtoxinB acts when injected into salivary glands.

How should this medicine be used?

A doctor must administer rimabotulinumtoxinB injection as a liquid into the afflicted muscles or salivary glands. To treat your disease, your doctor will determine the ideal location to inject the drug. Depending on your condition and the length of time the effects of the treatment continue, you might require further rimabotulinumtoxinB injections every 3 to 4 months.

RimabotulinumtoxinB injection will likely be administered to you by your doctor at first at a low dose, and when you respond to the drug, your doctor will gradually increase the dose.

It is not possible to switch from one botulinum toxin brand or kind to another.

Other uses for this medicine

The injection of rimabotulinumtoxinB is also occasionally used to treat various disorders in which pain, odd motions, or other symptoms are brought on by aberrant muscular tension. Other conditions that can be treated with rimabotulinumtoxinB injection include anal fissures, overactive bladder (a condition in which the bladder muscles contract involuntarily and cause frequent urination, an urgent need to urinate, and inability to control urination), and specific types of migraine (a split or tear in the tissue near the rectal area). The dangers of using this drug for your illness should be discussed with your doctor.

Ask your doctor or pharmacist for more details if you believe this drug should be used for something else.
