Period Delay Tablet Information

How Do Period Delay Tablets Work?

Utovlan also known as Norethisterone period delay pills work in a similar way to the hormone progesterone, which occurs naturally in the
body. It delays your period until the tablets are stopped. You will need to take one tablet three times a day,
starting three days before your period is due to start and continuing for no more than 14 days afterwards (17 days
in total). Your period will be delayed while you are taking the tablets and should start within three days of
stopping the tablets.

What do Utovlan period delay tablets contain?

Utovlan period delay tablets contain Norethisterone which is a form of progesterone, a female hormone, which prevents
your uterus from getting rid of its lining as it usually does, when menstruation begins. It comes in the form of a
tablet and the dosage strength to delay periods is 5 mg three times daily. You are required to start taking the
tablet at least three days before your period is due and to continue taking it for the duration that you would like
to delay your period.

How long can you take period delay tablets for?

It is recommended that Norethisterone 5mg tablets should be taken to delay your period for a maximum of 17
days. It is perfectly safe to delay your period for this amount of time. After you stop taking the tablets, your
period is likely to start after two or three days, however the time scale may be different for every individual.
This dose of Norethisterone is not recommended for prolonged use, as it can cause side effects and affect your
hormone balance.

How do I take the treatment?

Norethisterone 5mg tablets should be taken three times a day, usually at the same time each day. If you
forget to take a tablet on one day, you may continue taking the regular dose on the following day, or when the next
dose is due. Do not take two doses together. Read the patient information leaflet, as this will give you more
information about the medicine.

Will I get any side effects?

Norethisterone does not normally cause side effects as it is taken for such a short period of time. However,
the most common side effects which some women may experience are rashes, itching, dizziness and headaches, nausea
or depression. More serious side effects can include thrombosis or jaundice, fluid retention (which can lead to
high blood pressure) and migraines.

Will the tablets protect me against pregnancy?

Norethisterone cannot protect against pregnancy, as it is not a contraceptive. You may wish you consider
taking the combined oral contraceptive pill to prevent pregnancy. The combined oral contraceptive can also be used
to delay periods, when the ‘tablet free’ interval is omitted.

What do I do if I don’t get my period after I stop taking these?

Some women may not observe their period a few days after they stop treatment with Norethisterone, but it may
be slightly delayed whilst your body takes time to re-adjust to the hormone changes. However, its recommended to
take a pregnancy test if you do not get your period within a week of ceasing treatment, to rule out the possibility
of pregnancy. The period delay tablets are not a contraceptive and you should always use extra contraceptive
methods during treatment. If you still do not observe your period, you should seek medical advice.

On what day of my cycle should I start taking them?

You can take one Norethisterone tablet three times a day, starting three days before you expect to start your
next period. You should keep taking the tablets until you are ready to re-start your period (maximum treatment is
17 days).

Norethisterone is safe to take with a lot of medicines. However, there are some medicines, which are unsuitable
when taken with it. The following medicines are unsuitable to take with Norethisterone:

small number may experience light bleeding.

Side Effects of Norethisterone
