Candidates for Botox are physically healthy. They should be realistic about the range of cosmetic outcomes that are made possible by Botox.
Patients with neuromuscular disorders, deep scars, skin disorders, and marked facial asymmetries may not be candidates for Botox due to risk of complications. Additionally, patients who are pregnant or breastfeeding are not good Botox candidates. Patients who have pre-existing medical conditions that cause muscle weakness, swallowing or speaking difficulties, or breathing issues may not be candidates. If you are considering a Botox injection, consult a qualified doctor about your goals and expectations beforehand to make sure they are realistic.
No real preparation is needed for Botox injections, since it is a fairly simple procedure. That being said, certain things will increase the likelihood of great results and minimize the risk of bruising. One of the best things to do is avoid any anti-inflammatory pain relievers. These include: Ibuprofen, Tylenol, Advil, Motrin and most over-the-counter pain medications. If you take any other medications that thin your blood, these may also contribute to greater likelihood of bruising. Smoking will also increase your chances of bruising.
Side effects are extremely rare. However, the the most common is a headache that usually resolves in 12 hours and responds to any pain reliever. Otherwise, patients experience redness or small amounts of bruising at the injection sites. For some, dropping of the eyebrow or eyelid may occur, but this occurs in less than 5% of cases. Any redness and bruising usually resolves in less than 24 hours.
Botox has very few risks and a long history of safe usage in patients for both cosmetic and medical reasons. However, as stated above, drooping of the eyebrow and eyelid may occur. Flu-like illness, pain and headache are also among more common side effects of Botox, but usually go away after a short period of time.
Serious health complications, such as allergic reactions, problems swallowing or breathing, and the spread of the toxin can occur. However, these usually occur in cases where a larger dose of Botox is being used or when Botox is being used to treat disease or alleviate pain, rather than for cosmetic reasons.
