Botox Side Effects and Safety

Botox injections are primarily well-known for their potential to decrease or improve the appearance of wrinkles on the face. The drug is also used in the treatment of a range of other conditions, including neck spasms, overactive bladder, lazy eye, and excessive sweating. The injections have also been found to treat chronic migraines. However, considering this drug is made using onobotulinumtoxinA, is it safe? This is an excellent question to ask, especially when you consider the toxin is created by microbes that cause botulism, which is a type of food poisoning. 

As is the case with any medication, Botox® has some side effects. The side effects will depend on the dose, injection site, frequency, and the physician’s level of expertise. The majority of side effects are transient and appear a few days after treatment. Such side effects include soreness, tenderness, or bruising at the injection site.

For Botox injections done around the face and eyes, brief bruising, dry eyes, eyelid drooping (ptosis), and double vision (diplopia) are the most frequently reported side effects (Tan 2002; Hsiung 2002). It is important to note that facial droop can also happen with cheek injections. All in all, it is typically recognized that these side effects are generally uncommon when administered by knowledgeable medical professionals.

Although quite unlikely, the toxin in the injection can spread to other areas, mostly around the treated area. For this reason, patients are advised not to rub or massage a treated area for at least 24 hours. When the toxin spreads, you must call your doctor immediately. Common signs that the toxin has spread may include:

  • Vision problems 
  • Muscle weakness
  • Loss of bladder control
  • Trouble swallowing or speaking 
  • Difficulty breathing 

To further prevent adverse side effects, doctors will advise against using Botox while breastfeeding or pregnant. The treatment is also not ideal for persons allergic to the protein in cow’s milk. 

Some of the most frequent adverse reactions in individuals receiving Botox® for cervical dystonia are neck pain, dysphagia, headache, and upper respiratory infection. Most side effects result from improper administration of Botox. This happens mostly when a lot of toxin is administered. It may also occur when the proper quantity is injected but into the wrong muscle. If any of these mistakes are made when using Botox® on the face and neck, certain problems may result. Incorrect injections around the eyes or the forehead might result in drooping lids. There is also the fact that excessive injections in the neck can weaken the muscles and make swallowing difficult. In general, Botox® is safe and is not known to have any permanent negative effects when administered at prescribed doses by knowledgeable medical professionals.

The little long-term clinical data available indicate a drug with a solid safety track record. In a trial involving 65 patients who had repeated injections over a ten-year period, all side effects were transient, mild, and improved over time (Defazio 2002). Examining the ocular muscles following Botox® injections has demonstrated that multiple injections do not result in permanent muscle atrophy (wasting) or other degenerative changes (Borodic 1992), and muscle function goes back to usual following injection (de Paiva 1999). A significant research of 235 patients revealed a 75% benefit after treatment for at least 10 years for hemifacial spasm, blepharospasm, and cervical dystonia. While about 27% of participants in the study experienced side effects, only 1.3% of the participants dropped from the study due to intolerable side effects (Hsiung 2002). 

It has not been demonstrated that Botox® injections alter your muscles permanently or result in any long-term issues. Muscle weakening, the intended adverse effect of Botox® therapy, is frequently what patients experience after their injections. It is important to inject a precise amount of medication into the right muscle. This makes finding a qualified medical professional very important. This is due to the fact that many side effects are caused by incorrect injection placement or excessive dosage. The right medical professional will definitely help you avoid reported Botox side effects.

Choosing a Doctor 

Botox should only be used under a doctor’s supervision. To prevent negative effects, injections must be positioned properly. If botox therapy is applied inappropriately, it might be harmful. Ask your primary care physician for a recommendation, or look for a physician who specializes in your problem and has expertise in giving Botox injections. A qualified and skilled doctor can give you advice on the process and help you decide if it’s the ideal fit for your health and needs.

Getting Ready for the Treatment

If you’ve received any form of Botox injection within the last four months, let your doctor know. Additionally, let your doctor know if you use sedatives, sleep aids, or medication for allergies. To lessen your risk of bleeding or bruising, you might need to suspend the use of blood thinners for a few days before getting the injection.

Most people experience little to no discomfort when getting the treatment. However, you may want to get your skin numbed before the injections are made. This is more so if the treatment is being done on your soles or palms to treat excessive sweating. The doctor may use various numbing methods, including vibration anesthesia and topical anesthesia. 

When the procedure starts, the doctor will use a tiny needle to administer small quantities of Botox into the muscles or skin. The number of injections will vary depending on several factors, including the size of the area being treated. To keep the toxins from spreading to undesired areas, you must resist the urge to massage or rub the treated area for at least 24 hours. You can easily go back to regular activities right away after the procedure. The results from the injection will, however, become noticeable after 1 to 3 days. How long the results last will depend on your body type and the condition being treated. Typically, the results last about 3 to 4 months. Regular follow-up injections will be needed to maintain the effects. 

There are so many clinical trials that have been done over the years. Based on the findings, you can be certain that you will not suffer permanent effects from Botox injections. As aforementioned, side effects result from the improper administration of Botox. Consequently, the key to avoiding adverse side effects is using a qualified doctor.
