Botox Side Effects: What to Look Out

Posted on March 13, 2022

Botox has been trusted by millions of patients and doctors worldwide. However, just like any treatment Botox side effects may occur.

But what are the Botox side effects you must watch out for? Do they put you at risk?

In this article, we will talk about Botox, its benefits, and its side effects.

Botulinum Toxins

Botulinum toxins are types of neurotoxins. It affects nerves and causes muscle paralysis. Clostridium botulinum, a type of bacterium makes these neurotoxins. For medical injections, healthcare providers use a specific type of bacteria (type A).

Doctors use it in small doses to treat health issues such as wrinkles, severe underarm sweating, uncontrollable blinking, misaligned eyes, and cervical dystonia, a disorder that causes extreme shoulder and neck pain due to muscle contractions.

Technicians develop botulinum toxin injections for cosmetic and medical procedures in a lab. Moreover, technicians dilute and sterilise the toxins so they won’t cause botulism.

Botulinum toxin can be used for both medical and cosmetic reasons.

What Is Botox Made Of?

Botox is a drug that causes weakness or paralyses of muscle. In certain doses, it can reduce skin wrinkles and help treat some medical conditions. In fact, Botox is among the best non-surgical treatments in London.

The Food and Drug Administration (FDA) has approved Botox as a treatment for various health issues, including eyelid spasms, excessive sweating, some bladder disorders, and migraine.

Botox London, a popular cosmetic treatment, is made from Botulinum toxin.

Botox Benefits

Here are the benefits of Botox:

Enhances Natural Beauty

One of the most significant benefits of getting Botox is it enhances your natural beauty. Botox can be also used as an anti-aging treatment to lessen the appearance of wrinkles.

Botox offers several benefits such as improving issues like bladder disorder and wrinkles.

Improves Many Health Conditions

Other than improving your physical appearance, Botox injections can improve a lot of other health conditions as well.

For example, many people who suffer from muscle contractions can use Botox injections to improve their condition. It’s because Botox in London, UK can block the nerve activity in muscles. Additionally, it can prevent unnecessary use of muscle use as well.

Those who suffer from severe underarm sweating, urinary incontinence, or even an overactive bladder can also benefit from getting Botox injections.

However, Botox continues to work for about three months after your injections. Usually, you will notice your wrinkles and frown lines continually relax until you achieved the maximum results.

Botox Safety

Although botulinum toxin is life-threatening, small doses of it — like those used in the application of Botox — are considered safe.

In fact, only 36 cases of adverse effects were reported to the US Food and Drug Administration. This is between 1989 and 2003. These effects are associated with cosmetic use. Thirteen of these cases may have had more to do with an underlying condition than with the Botox injection itself.

With that in mind, researchers speculate that cosmetic applications carry less risk than therapeutic Botox injections, as the doses are usually much smaller.

One well-cited 2005 study found that adverse effects are more likely to be reported with therapeutic use. The adverse effects may be related to an underlying condition. However, it can also be caused by higher doses needed to treat the condition.

A review of studies in 2021 concluded that some people who were given Botox injections experienced:

  • superficial reddening of the skin
  • swelling
  • drooping eyelid or brow
  • pain in the injected area
  • other skin discolorations

The majority of these side effects were mild and temporary. Thus, Botox is considered safe.

You should always go to a board-certified cosmetic doctor for Botox injections. You’re more likely to experience adverse side effects if your injections aren’t prepared according to FDA standards or are injected by an inexperienced doctor.

You should also wait to receive Botox if you’re pregnant or breastfeeding.

Is Botox Dangerous?

It can be dangerous if botox will be administered by an individual who does not have the appropriate training and experience to perform this procedure.

Yes. Botulinum toxin can be dangerous in large doses and produce side effects. It can also be dangerous in the hands of an amateur injector. However, professionally-done Botox injections come in smaller doses. The procedure is both safe and effective as long as it’s performed by a professional.

Botox is not dangerous if administered by the right professional.

Botox Risks: Botox Side Effects in Forehead

When performed by an experienced cosmetic surgeon, Botox injections are relatively safe. Possible side effects of Botox include:

1. Pain at the Injection Site

After an injection, swelling and irritation (inflammation) can occur at the injection site. This is a common reaction to the needle or injected medicine.

It may also be a reaction to both. The reaction (sometimes an allergic reaction) may happen right away or it may only begin hours after the injection. Mostly, reactions are not severe and will subside on their own.

The most common cause of the said reaction is the skin’s response to the needle or the medicine. Less common causes include allergic reactions to the medicine or an allergic reaction to Botox itself. However, the allergic reaction caused by these rarely happen.

Treatment depends on the cause and how bad the allergic reaction is. Most post-injection allergic reaction is mild. Side effects go away on their own in hours or days. If needs remedy, it may include:

  • Cold packs: Can help reduce swelling, pain, and itching.
  • Over-the-counter pain relievers: Can help reduce pain and inflammation, and helps relieve pain from infection (e.g. tract infection).
  • Prescription medicine: Can treat an infection (e.g. tract infection).

2. Swelling

Swelling causes an increase in the size or a change in the shape of a specific area of the body. Swelling can be caused by a collection of body fluid, tissue growth, or abnormal movement or position of tissue.

Some people experience swelling at the injection site after getting Botox injections. It’s one of the common side effects. However, just like other common side effects, swelling usually goes away quickly, in about one to three days. Cold packs and medication can be used to treat the swelling.

In addition, a majority of patients do not experience swelling after getting Botox.

Tell your doctor if you experience any side effects for medical advice or prescriptions.

3. Bruising

After receiving Botox, it’s rare to experience bruising. However, it can happen to some people. Even the best cosmetic surgeons can cause bruising to a patient after administering botox.

Oftentimes, bruising occurs when the needle pricks a blood vessel. This causes the blood to leak below the surface of the skin. Eventually, reddish and/or purple marks will appear on the surface of the skin as a result.

Patients taking blood thinners have higher chances of getting bruises. These blood thinners include aspirins and ibuprofens.

Additionally, the risk of bruising becomes higher in patients who frequently consume alcoholic beverages. Alcohol consumption increases blood flow. This results in increased inflammation in the treated area.

Bruising due to botox is mainly caused by blood extravasation. Commonly, it’s the leaking of blood from a blood vessel. The blood will then accumulate and settle into the surrounding tissues.

Bruising happens if the Botox needle accidentally punctures the blood vessel. Regardless of whether it’s a skilled or beginner cosmetic doctor, bruising can still occur. It’s because blood vessels are numerous and can be difficult to see sometimes.

Blood extravasation can also be caused by:

  • Blood-thinning medications and supplements prior to the Botox procedure
  • Alcohol consumption before or after the procedure
  • Doing strenuous exercise before or after the procedure

Bruising acquired from Botox usually lasts a few days. However, it could also last up to two weeks. After the procedure, it may appear immediately, or after a day or two. The reaction depends on the physical predispositions and activities of the patient.

Bruising is common after botox injections. However, you can take some steps to avoid or minimize bruising. Also, you should always speak to your doctor about your health status.

Tell your doctor if you experience any common side effects that become severe.

4. Headache

Following a Botox injection, some people experience a mild headache. The headache caused by botox can last a few hours to a few days. In rare cases, the mild headache can last for weeks or develop into flu like symptoms. If this is the case, consult your doctor.

About 1 percent of patients experience severe headaches after getting botox. The side effect can last for two weeks, even up to one month before it gradually disappears. This is according to a study involving clinical trials from 2001.

Some people experience a headache after a Botox. However, Botox can also be used to treat headaches. A study from 2010 indicated that Botox could be used in preventing chronic headaches and chronic migraine.

A mild headache after Botox can be treated with OTC pain relievers. Headache should disappear in a matter of hours. Sometimes, it could take a few days at most.

If you experience a severe headache and your headache does not respond to an OTC drug, call your doctor for any diagnosis or prescriptions. The same applies to when you have flu like symptoms.

5. Slight Muscle Weakness

The use of Botulinum toxin which is present in botox results in muscle weakness, atrophy, and loss of contractile tissue. Mostly, the affected will be the non-injected muscles that are far from the injection site.

Some benefits of using Botox can be therapeutic. Therefore, it outweighs the potential long term consequences.

Botulinum Toxin A which is the content of botox paralyzes some muscles in the face. This toxin helps reduce the appearance of wrinkles as well.

The poisonous substance in botox causes the muscles to weaken. It’s because of the effect of botox on the nerves. Botulinum toxin in Botox can be used both for cosmetic and therapeutic reasons.

If caused by Botox, it’s only a temporary side effect. You don’t have to worry about it being long term.

People with muscle-nerve conditions have a greater risk of experiencing serious side effects from Botox. These effects include muscle weakness, blurry vision, drooping eyelids, and trouble speaking. Trouble swallowing and drinking may also be experienced.

Call your doctor if you get drooping eyelids and/or experience trouble swallowing, trouble drinking, or trouble breathing (i.e. difficulty breathing).
