The most common side effects of Botox injections are neck pain and stiffness at the injection site. You may develop a headache afterward. You may also experience temporary muscle weakness in your neck and upper shoulders. This can make it hard to keep your head upright. When these side effects occur, they usually resolve on their own within a few days.
Remember that the skill of the injector is extremely important when considering Botox injections. Because Botox can have some very obvious and embarrassing side effects like drooping eyelids, blurry vision, and excessive bruising around the injection site, it's important to consult with an experienced injector. Unlike dermal fillers which can be melted away with a follow-up injection of hyaluronidase, there's not much you can do about a bad Botox experience other than wait it out.
Are you ready to put your best face forward, but fear that Botox and other “lunchtime facelifts” are out of your budget? Are you wondering, “How much does Botox cost?” You may be pleasantly surprised to learn that some of the most popular and effective cosmetic treatments available are well within reach. A quick word of warning, though: If the prices seem too good to be true, they probably are. The products may be diluted or the treatment provider inexperienced. It’s worth spending a little extra time and money to get the results that you’re dreaming about!

Unlike a face lift or other kind of invasive facial rejuvenation procedure, treatment takes minutes and requires zero downtime. Using a very fine needle, Botox is injected into the facial muscles that are responsible for unsightly wrinkles and fine lines and relaxes the muscles. The ingredients in Botox block the signal from the nerve to the muscle, and therefore reduce it’s ability to contract, and form unsightly wrinkles.

"We were very skeptical," says Edwin Chapman, a professor of neuroscience at the University of Wisconsin--Madison, after reading Caleo's study. But in August 2016, Chapman and his graduate student Ewa Bomba-Warczak published a study in the journal Cell Reports showing similar spreading effects in animal cells in the lab. For Chapman, it explained what he was hearing anecdotally from doctors: that Botox might be influencing the central nervous system and not just the area where it's being injected.
In fertility studies of BOTOX (4, 8, or 16 Units/kg) in which either male or female rats were injected intramuscularly prior to mating and on the day of mating (3 doses, 2 weeks apart for males, 2 doses, 2 weeks apart for females) to untreated animals, reduced fertility was observed in males at the intermediate and high doses and in females at the high dose. The no -effect doses for reproductive toxicity (4 Units/kg in males, 8 Units/kg in females) are approximately equal to the maximum recommended human dose of 400 Units on a body weight basis (Units/kg).
A migraine requires only two of the following headache features: a unilateral distribution (one-sided), pulsatile quality (throbbing), moderate or severe pain (more than 5 out of 10), and aggravation by physical activity (such as bending over). In addition, to diagnose migraine, only one of the following is required: nausea or vomiting or sensitivity to light and noise.
In a study to evaluate inadvertent peribladder administration, bladder stones were observed in 1 of 4 mal e monkeys that were injected with a total of 6.8 Units/kg divided into the prostatic urethra and proximal rectum (single administration). No bladder stones were observed in male or female monkeys following injection of up to 36 Units/kg (~12X the highest human bladder dose) directly to the bladder as either single or 4 repeat dose injections or in female rats for single injections up to 100 Units/kg (~33X the highest human bladder dose).
Side effects from cosmetic use generally result from unintended paralysis of facial muscles. These include partial facial paralysis, muscle weakness, and trouble swallowing. Side effects are not limited to direct paralysis however, and can also include headaches, flu-like symptoms, and allergic reactions.[27] Just as cosmetic treatments only last a number of months, paralysis side-effects can have the same durations.[citation needed] At least in some cases, these effects are reported to dissipate in the weeks after treatment.[citation needed] Bruising at the site of injection is not a side effect of the toxin but rather of the mode of administration, and is reported as preventable if the clinician applies pressure to the injection site; when it occurs, it is reported in specific cases to last 7–11 days.[citation needed] When injecting the masseter muscle of the jaw, loss of muscle function can result in a loss or reduction of power to chew solid foods.[27]

Results can vary depending on who is performing the injection on the patient. It is very important to go to a physician who is experienced at this procedure, does it him- or herself (rather than having a nurse, physician's assistant [PA], or other nonphysician do it), and has a good reputation for performing this type of procedure. The manufacturers of Botox recommend physicians inject the medication themselves. As with most procedures, the skill of the practitioner is related to how often he or she performs the procedure.
When moving a spastic limb through its range of motion, one feels a resistance to movement that increases with the speed at which one moves the limb. This is the definition of spasticity, but other terms such as increased muscle tone, hypertonicity, spastic dystonia, or flexor / extensor spasms are used to describe this resistance. In clinic the term "muscle spasticity" will be used to reduce confusion of terms.
I increase the dose at each treatment cycle to 195 units. This is based on experience with patients with cervical dystonia, in whom higher doses result in a longer duration of effect. In addition, I transition to the next onabotulinumtoxinA treatment at 12 weeks by using occipital and trigeminal nerve blocks at 10 weeks. Most insurance companies will not cover onabotulinumtoxinA treatments earlier than 12 weeks, but in rare cases, 10-week cycles have been approved.

"I have treated people with profound migraine headaches and it turns them right off," says Dr. Matarasso. "If you feel it coming on, it stops it, reducing the severity as well as the duration. I had a patient [who was] in college who had unremitting migraine headaches. She changed her diet, she changed her birth-control pill, she had acupuncture. I finally said to the mother, 'We need to try Botox,' and it has been a complete life-changing event for this woman." 

Not a Botox patient? Listen anyway. This is good practice for asking the price for other medical procedures like an MRI or a colonoscopy, where the information can be much harder to get. The common replies you could get: “What’s your insurance?” “We can’t tell you because it depends on your deductible.” “We don’t know.” “You’ll have to call billing.”

Medicine to help the patient relax may be given in cases where the patient has not handled shots well in the past. If the patient has another procedure coming up, these shots can often be done at this time. Let the Rehabilitation Medicine office (513-636-7480) know if a procedure or surgery will be done in the future or if sedation is being discussed for injections in the clinic setting.
After a muscle has been injected, the nerves still send the signal to the muscle to contract, and the acetylcholine is still released, but is unable to bind to the muscle, resulting in a reduction of muscle activity and temporarily preventing contraction of the muscles that cause frown lines. The binding process typically begins within about 48 hours from the time it is injected into the muscle, and results typically become noticeable within 7 to 10 days. While results are often most noticeable in dynamic wrinkles (wrinkles that appear when a muscle contracts), it can also help soften wrinkles that are present even without muscle contraction. If you’re serious about improving the appearance of moderate to severe frown lines, it may be just the right treatment option for you.
Most doctors suggest focusing on the quality of the skin with a proper regimen that includes daily exfoliation and SPF protection, as well regular chemical peels or specialized treatments such as Clear and Brilliant laser resurfacing during this decade. Still, there are exceptions. If constant eyebrow furrowing has resulted in the first signs of an angry crease or premature crow’s feet due to naturally thin skin are a persistent cause of frustration, injectibles can help. But as any good dermatologist will note, there is a caveat: When it comes to Botox and filler, there's a fine line between targeted tweaks and doing too much too soon. Here, in-demand experts share their guidelines for women in their 20s.
Other side effects of BOTOX® and BOTOX® Cosmetic include: dry mouth, discomfort or pain at injection site, tiredness, headache, neck pain, eye problems: double vision, blurred vision, decreased eyesight, drooping eyelids, swelling of eyelids, dry eyes, and drooping eyebrows. In people being treated for urinary incontinence other side effects include: urinary tract infection, painful urination, and/or inability to empty your bladder on your own. If you have difficulty fully emptying your bladder after receiving BOTOX®, you may need to use disposable self-catheters to empty your bladder up to a few times each day until your bladder is able to start emptying again.
