The use of the word "effect" is wrong in this case. It should be "affect".
There are certain words that may sound similar and may even have the same spelling or close. But at the same time, their meanings may be completely different.
- In the given sentence, "this medication may effect your mental alertness", the use of the word "effect" should be replaced by "affect".
- This is because "effect" is a noun whereas "affect" is a verb.
- And looking at the sentence's context, the error is in the wrong use of the word for the verb.
When the noun is replaced by the verb, it becomes perfectly correct. It then now states "this medication may affect your mental alertness" which has a correct construction.
