What are the chances of an allergic reaction to Botox?

If you’re thinking about getting Botox, you’re probably worried about whether or not you’re at risk for an allergic reaction from this treatment. Simply put, Botox can cause allergic reactions, but it’s not all that likely. However, there are some types of allergic reactions to Botox that are a little bit more common than others.

Many people experience at least a little bit of pain, redness, or swelling shortly after Botox treatments. This doesn’t necessarily mean you’re having an allergic reaction, but it can be an early sign of something like this going on. If this happens, you should be prepared for the possibility of more allergic responses from the list in the following section.

Keep in mind, too, that severe, life-threatening allergic reactions are very uncommon with Botox. It is possible, however, to develop a botulism infection from having Botox, although this is also incredibly rare. For the most part, if you’re getting your treatments from a reputable source and you’re following the directions from your skin care specialist or dermatologist, you’re probably not going to have to worry about anything like this.

Botox Allergy: 10 SYMPTOMS To Watch Out For

There are several symptoms you should be on the lookout for if you’re concerned about Botox allergies. In this section, we’ll walk you through all of the possible risks you may encounter and let you know which ones are more common and which are much less likely. We’ll also be sure you know which ones you should be more concerned about, too.

symptoms of allergy to botox
  • Pain at the injection site. This is the most common reaction to Botox injections, and it’s not necessarily a sign of an allergic reaction. It can signify that you may need to expect more allergic responses as your body starts to heal, however. It’s perfectly normal to experience pain from the Botox injections for a few hours to about a day afterward, but if it lasts longer than this, then you might need to pay more attention to the risk of allergy.
  • Bleeding. If your Botox injection site is bleeding for more than an hour or so after your treatment, you should call your dermatologist or skin care specialist and ask about this. In some instances, patients may have thinner skin that is simply more prone to bleeding, and this may go away without causing any significant problems. However, most of the time, this is a sign that your body may not be responding well to the treatment, and you should be wary of further signs of allergies as you continue to heal.
  • Bruising. You may notice some light bruising from the shots themselves, and if you do, this is also pretty normal. Sometimes, your skin may just be more likely to bruise from having a shot. If you’re the kind of person who gets a bruise from giving blood, for example, this may happen to you. If the bruising is very severe, however, be sure to speak to your dermatologist, as this could signify something more serious.
  • Redness or welts. Redness and welts are almost always sure signs of allergic reactions to Botox. However, they are usually signs that the allergy is simply on the surface of your skin and is not going any deeper or getting any worse than this. You may break out in hives or develop a wide, red, flat rash if you’re allergic to your Botox treatments.
  • Swelling. As with bruising and some pain at the injection site, you’re likely to notice a little bit of swelling for the first couple of days after your treatment. If this swelling gets very severe, gets worse over time instead of getting better, or doesn’t go away within 48 hours, you should talk to your dermatologist. If you start off pretty swollen but notice the swelling going down steadily, this is normal, and you should be fine in a day or two.
  • Itching. Itching, like welts and redness, is another very common sign of an allergic reaction to Botox. If you are itching very badly more than a few hours after treatment, you may have an allergy. And if the itching gets worse, you need to go to your doctor or dermatologist right away, as this could mean your body isn’t going to respond well to the Botox. Itching on its own isn’t a serious problem, but it can be a sign of something worse to come.
  • Wheezing. If you hear yourself wheezing when you breathe in or out, this is a very serious sign of allergic reaction and you need to get to your doctor or to a hospital as soon as possible. This is not a normal reaction to Botox.
  • Faintness. Faintness is also not a normal reaction. If you are feeling faint, weak, or very lethargic after your treatment, get to a hospital or to your doctor right away.
  • Dizziness. If you’re feeling dizzy following your treatment (and the dizziness is not related to any sedatives or anesthetics you may have been given), you should speak to a health care professional immediately.
  • Shortness of breath. If you’re having trouble breathing, this is a sign that your body is severely allergic to your treatment. Go to the hospital if you can’t breathe well following your Botox treatment. Bear in mind, however, that this is a very rare side effect.


As you can see, Botox allergies are not usually very severe, but there’s always a chance they can be. Pay close attention to your body to be sure you’re not experiencing something that requires medical attention following your treatments. And remember to do everything your dermatologist tells you in order to keep yourself healthy and responding well to your Botox treatments every time you have one. A little self-care can go a long way toward preventing a bad reaction.
