Stomach upset, nausea, or constipation may occur in 1 to 10% of patients. Symptoms are reported as mild or moderate and usually last from a few days to two weeks. Upper respiratory tract infection is a common side effect of Botox. The common cold is an example of this type of infection.
In people taking Botox, these infections are usually mild. Botulinum toxin can cause allergic reactions. These reactions consist of a broad spectrum of symptoms, ranging from edema, erythema or redness limited to the injection site, through diffuse erythema and generalized urticaria to anaphylactic shock. Erythema should calm down within 24 h; if it lasts longer, an antihistamine may be helpful.
If this is an anaphylactic reaction, then this is a medical emergency. In such circumstances, treatment with an injection of adrenaline and continuous monitoring of the patient should be implemented. To help prevent allergic reactions, a thorough medical history should be performed to rule out previous allergic reactions to other brands of botulinum toxin, and doctors should exercise special caution when treating people with multiple allergies, as they may be at increased risk of being allergic to botulinum toxin. When you decide to book your first appointment with a wrinkle relaxer, it's essential to know how it works and what potential Botox side effects can occur.
Botox may not be right for you if you have certain medical conditions or other factors that affect your health. If you have injection site reactions that are severe or bothersome to you, talk to your doctor about other treatments besides Botox that might be better for you. It is also not known if botox enters breast milk or if it can affect a breastfed child. If your doctor confirms that you had a severe allergic reaction to Botox, he or she may change you to a different treatment.
Two hundred and thirty-one patients enrolled in a double-blind, placebo-controlled study (the study received 300 to 400 units of BOTOX, and compared with 233 patients who received placebo. Most Botox side effects usually go away after a few days or weeks as the effects of the injection wear off. Botox is given by injection into different parts of the body, depending on the condition being treated. It is especially important to seek medical help right away if you have trouble breathing, swallowing, or talking after receiving Botox injections.
The formation of neutralizing antibodies against botulinum toxin type A may reduce the effectiveness of BOTOX treatment by inactivating the biological activity of the toxin. The most common side effect in children and adults who used Botox for bladder problems was urinary tract infection (UTI). In studies, urinary retention was commonly reported in adults who received Botox injections to treat bladder problems. Rubbing or massaging the Botox injection site may increase the risk of the toxin spreading to other areas.
If you have ever had an allergic reaction to Botox or any of its ingredients, you should not take Botox. The most common adverse events leading to discontinuation of BOTOX treatment were neck pain, headache, worsening migraine, muscle weakness and eyelid ptosis. There are two classes of adverse events related to Botox: transient and benign events and potentially serious events.
