Norethisterone 5mg tablets are available from The Independent Pharmacy Online Doctor service, following a free consultation, to help delay the start of menstruation (period) in women. To find out more about period and see all the available treatments, see our Period Delay page.
Norethisterone is a synthetic version of progesterone, a natural female sex hormone that sustains the lining of the womb in women. Normally before a woman has a period the progesterone levels fall, however taking Norethisterone will sustain the womb lining and delay a period until the tablets are stopped.
Norethisterone can safely be used to delay a period for up to 17 days where it would otherwise be inconvenient.
Norethisterone 5mg tablets can be purchased from the Online Doctor to delay your period for:
Up to 7 days period delay = 1 pack (30 tablets)
Up to 17 days period delay = 2 packs (60 tablets)
Norethisterone should not be used to delay your period for more than 17 days without a face-to-face consultation with your GP. It should not be used more regularly than every 4 months.
Norethisterone was first released as the branded medicine Utovlan, however it is now available as a generic treatment following the patent expiry of Utovlan. This means that Norethisterone is available at significantly reduced cost as a generic treatment for period delay.
Norethisterone is also present in some contraceptive pills and hormone replacement therapies for menopause. Norethisterone 5mg tablets should not be used for hormone replacement and do not offer any contraceptive cover. Your normal contraceptive method should still be used whilst you take Norethisterone 5mg tablets.
Norethisterone should be taken three times daily starting 3 days before your period is due until you wish your period to resume. Once Norethisterone has been stopped, a normal period will be experienced within 2 – 3 days. Norethisterone should not be taken if you are or could be pregnant. Norethisterone does not have any special dietary measures, it's absorption and effects are not changed by food or alcohol.
If you are already taking the contraceptive pill, this can normally be used to delay your period and Norethisterone will be unsuitable for you. See our Period Delay page for advice on using your contraceptive pill to delay your period. You should always read the patient information leaflet in with your contraceptive pill before running pill packs together.
Women who take the contraceptive pill can generally run 2 packs together to delay their period without consequence. If you are in any doubt, contact your GP.
You should take one Norethisterone 5mg tablet three times daily, starting 3 days before your period is due.
Continue taking Norethisterone until you wish to have your period.
Your period should come within 2 – 3 days after stopping Norethisterone.
If you miss a dose, take it as soon as you remember unless your next tablet is nearly due, in this case skip the missed dose and take the next dose at the normal time. You may find that if a dose is late or missed you experience some light bleeding/spotting. It is therefore advised to have some panty liners or similar if needed.
1 pack (30 tablets) = 7 days period delay
2 packs (60 tablets) = 17 days period delay
