Explanation

It is split-infinitive related error. A Split-infin itive is one, when an Inf. is split by using something (usually an Adv.)
between the two parts of the Inf. i.e to and a Verb
`{:("to read → Inf"),(" "darr),("Verb"),("to happily read → Split Inf."),(" "darr),(" "Adv.):}`
use of split - infinitives is incorrect.
Hence to take the medicine regularly is the right usage.
