Many physicians would agree that aspirin and antibiotics are potentially more harmful than Botox.

However like any drug, anaphylaxis can occur and Botox procedures should be performed by trained physicians in proper clinics with adrenaline on standby.

There is no evidence that Botox has any detrimental side effects, in fact to the contrary it has a built in mechanism to protect the patient by the use of new nerve regeneration.

On the contrary, although Botox can cause headaches in about 2-3% of people, it actually relieves them in the vast majority of patients treated.

It has been known for some time that Botox can help prevent and treat migraine sufferers. To do this, doctors usually inject it into various trigger points that can differ from patient to patient. The duration of action of Botox in migraine prevention varies from about 10 to 13 weeks and the onset of effect may take a few weeks.

Ideally, the medication should not be administered more frequently than every 3-4 months.

On the contrary, an injection of Botox is usually quite painless. The needle that is used to administer Botox is tiny, in fact it is the same size used by diabetics every day to give insulin.

Those who were given Botoxinjections compare their sensations to those experienced during an insect bite. Some patients do prefer applying an anaesthetic cream to the face about fifteen minutes before the procedure and this totally eliminates any possibility of pain.

There is no pain after injection as Botox works as a kind of anaesthetic itself.
