How to take your medication

  • How do I use it?

    You should always take your medication as described by your healthcare professional. Check with your doctor or pharmacist if you are not sure.

    The usual dose is one tablet taken orally every day. It will not work faster or better if you take it more than once a day.

  • If you take more tablets than you should

    If you take too many tablets by mistake, contact your doctor immediately.

  • If you forget to take a tablet

    If you forget to take a tablet, take the next one as usual, but do not take a double dose to make up for the forgotten tablet.

  • If you stop taking your medication

    You will need to keep taking your treatment to see the benefit, otherwise you may lose the hair you have gained so far within nine to 12 months.

    Visible results will not be immediate. With continuous use of your medication, you can expect to see evidence of stabilisation of hair loss in three to six months.
