It is proven to do so when injected into certain areas. A headache may also occur if a blood vessel is injured during a botox injection and a hematoma (pool of blood) forms. This can cause a headache along with the formation of a tender and bruising lump on the skin. You may experience a headache after receiving Botox, usually the day or the day after injections.
Some people experience a mild headache after an injection into the forehead muscles. It can last from a few hours to a few days. According to a 2001 study, about 1 percent of patients may experience severe headaches that can last from two weeks to a month before slowly disappearing. While there are quite a few myths about Botox, treatment can have minimal side effects.
For a very small group of patients, this side effect may include headaches. Botox-related headaches are extremely rare and are believed to be caused by excessive contraction of certain muscles of the face. Headaches that occur after treatment with Botox can be controlled. If headaches persist, they tend to decrease as the body metabolizes the drug naturally.
If you have a headache after treatment, you can ease the discomfort with over-the-counter pain medication for a few days. If, after this time, you still feel uncomfortable, contact your Botox provider. What can be done with this problem is that we can administer a lower dose on your next touch-up. The least amount of relaxation may be the trick to keeping headaches at bay.
The local weakness of the injected muscle or muscles represents the expected pharmacological action of botulinum toxin. As an example, for the prevention of chronic migraine, botox injections are divided into seven specific muscles of the head and neck. In patients with overactive bladder with specimens analyzed from the two phase 3 studies and the open-label extension study, neutralizing antibodies developed in 0 of 954 patients (0.0%) while receiving 100 unit doses of BOTOX and 3 of 260 patients (1.2%) after receiving at least one dose of 150 units thereafter. People who take Botox for the above conditions and who have diabetes or multiple sclerosis may be at increased risk of urinary retention.
Headache days and analgesic intake were recorded prior to Onabotulinumtoxin A injection and during interviews during the first, second and third months after Onabotulinumtoxin A injection. Other side effects included neck pain, muscle stiffness, muscle weakness, and pain or redness at injection sites. The good news is that headaches related to Botox injections appear to be mild and go away within a day or three after treatment. Extraocular muscles adjacent to the injection site may be affected, causing vertical deviation, especially with higher doses of BOTOX.
The most commonly reported adverse reactions following injection of BOTOX in paediatric patients 2 to 17 years of age with upper limb spasticity are shown in Table 22. You should not use Botox to treat urinary incontinence if you are unable to completely empty your bladder on your own. For nearly a decade and a half, Botox injections have provided a safe and effective treatment for facial wrinkles and folds, such as those on the eyebrow line and around the eyes. The most common use of these injections is to temporarily relax the facial muscles that cause wrinkles on the forehead and around the eyes.
There are no adequate studies of Botox in pregnant women and it has not been evaluated in nursing mothers. Botox has many other uses, including treating migraines and excessive sweating (known as hyperhidrosis). In addition, 44 adults received 400 units of BOTOX or more for four consecutive treatments for approximately one year for the treatment of upper limb spasticity. Your doctor will check your urine volume (how much you urinate) within 2 weeks after starting treatment with Botox to check for urinary retention.
