Based on the information available, I cannot provide an exact measurement of how "swift" Advil provides pain relief. However, Advil, also known as Ibuprofen, is a non-prescription, non-steroidal anti-inflammatory drug (NSAID) that is commonly used to treat pain, reduce inflammation, and lower fever [1].

According to the manufacturer, Advil starts to relieve pain within a short period of time. For instance, in a study of 182 adults with muscle aches, 600 mg of ibuprofen provided significant relief of muscle pain 1 hour after administration when compared to placebo [2].

It's important to note that the effectiveness of Advil can vary from person to person, depending on factors such as the severity of the pain, the individual's metabolism, and the dosage taken [3]. It's always recommended to follow the instructions on the label or consult with a healthcare professional for proper usage.

In conclusion, while I can't provide an exact measurement of how swift Advil provides pain relief, it has been shown in studies to provide significant relief within 1 hour of administration.
