The use of Botox for the treatment of wrinkles and skin aging has been approved by the FDA. This assures the public that the procedure's level of safety passed the strict standards of the FDA. However, this does not mean that there will be no side effects after the administration of Botox.
Short-term side effects
Just like with any injection, one of the noticeable side effects after the administration of Botox is redness, pain, or a slight tingling sensation at the site of injection even hours after the administration. This effect, however, should disappear a few days after the treatment.
Some people have also reported headache, nausea, flu-like symptoms, temporary eyelid droop, and respiratory infection after the Botox administration.
Very rarely, muscle weakness and spread of the effect of the injection to nearby areas may also be experienced.
If the Botox is not properly administered, it may result to having an uneven smile, inability to raise one's eyebrows, close an eye, or frown. These side effects of Botox should slowly vanish weeks after the Botox treatment.
Allergic reactions to Botox
Some people may just be sensitive to the contents of the Botox preparation. Allergic reaction to the contents of the preparation may manifest on the patient's skin. Redness, swelling, pain, and itchiness may occur. Nausea, headache, and difficulty in breathing may sometimes be experienced as an allergic reaction to the protein contents of the preparation. If a person experiences these allergic symptoms or if the person has an allergy to albumin, the physician must be notified immediately.
