    Exciting News for WebMD Members!

    We've been busy behind the scenes building new message boards for you. You'll have new and easier ways to find messages, connect with others, and share your stories.

    And, this will all be available on your smartphone or other mobile device!

    What Do You Need to Do?

    The message board you're used to will be closing in the coming weeks. While many of your boards will be making the move to our new home, your posts will not. Want to keep a discussion going? Save posts you want to continue (this includes your member profile story), so that you can re-post them in the new message boards.

    Keep an eye here and on your email inbox, we'll be back in touch soon to give you all the information you need!

    Yours in health,

    Drug Interactions

    Would taking a blood thinner like warfarin cause other drugs to take longer to work, or increase their onset time? If someone accidently took haloperidol, how long would it take before side affects to appear? Could a patient who takes blood thinners be negatively impacted by haloperidol? How?

    Hi Anon,

    For information about drug interactions please see our Drugs and Medications Center .

    Please contact your pharmacist to answer these very specific questions. It is important to take into consideration all medications you are taking and your medical history.

    For future or general questions, please see our Ask the Pharmacist .

    Hope this is helpful,
