Is there a more formal or better way of phrasing "in the future"?


Please refrain from using said substance in the future.

    Why do you think "in the future" is informal? Sep 2, 2014 at 15:50
  • "Please abstain from further use of substance X"

    What @Kevin said. But although in [the] future isn't "informal", it's not particularly "formal" either. Whereas henceforth is definitely a "more formal" alternative. Sep 2, 2014 at 15:58
  • Thank you for the comments. I guess as a non-native speaker I found it to be informal through my native tongue. I see now there's nothing wrong about it, however I do like the alternative henceforth.

In addition to the excellent suggestions by FumbleFingers (henceforth) and bib (prospectively), hereafter might work.

But as other commenters have observed, "in the future" is not at all informal. In fact, I would rate it as slightly more formal than the frequently heard "going forward" and "from now on"—and considerably more formal than "by-and-by."


In the future is likely redundant. You could just say,

Please refrain from using said substance.

The only situation in which you do need to say in the future would be if you caught someone in the act of using the substance, but wished to grant an exception to the rule for the current infraction. In that case, in the future would be a perfectly natural and formal way to express that.

  • That makes sense. I didn't realize I made the phrase redundant in the original example.

You could use the adverb prospectively. The adjective form prospective, defined in Oxford Dictionaries Online as

Likely to happen at a future date; concerned with or applying to the future: a meeting to discuss prospective changes in government legislation

In your example

Please prospectively refrain from using said substance.

However, it sounds beyond formal, sliding into stilted.


Henceforth may work if you mean "continuously in the future", but I don't believe it will work for a specific point in the future.


"Moving forward" / "Outlook"

Moving Forward:

  • "How will the UN manage the Syrian refugee crisis moving forward?"

  • "Lightning vs. USB-C: Which connector will Apple move forward with?"


  • "The Bitcoin Market: The outlook of cryptocurrencies and the roles they will play in the global economy."
  • "What is the short-term outlook of gas prices?"


@FumbleFingers is totally right in regards to how "in the future" is neither formal or informal.
