Norethisterone FAQs
What is Norethisterone?
Norethisterone is a synthetic form of progesterone, a natural hormone in women that helps maintain the lining of the womb. Normally, progesterone levels drop before a period starts, but Norethisterone helps maintain the lining, allowing you to delay your period until the tablets are stopped.
What is Norethisterone Used For?
Norethisterone is primarily used to safely delay your period for up to 17 days when it would otherwise be inconvenient. You can buy Norethisterone period delay tablets online from courierpharmacy.co.uk after completing an online consultation form. It is available in the following options:
- 1 pack (30 tablets) for up to 7 days of period delay
- 2 packs (60 tablets) for up to 17 days of period delay
Do not use Norethisterone to delay your period for more than 17 days without consulting your GP. It should not be used more frequently than once every 4 months and cannot be purchased over the counter. Originally marketed as Utovlan, Norethisterone is now available as a generic after the Utovlan patent expired. It is also used in some contraceptive pills and hormone replacement therapies, but it does not provide contraceptive protection and should not be used for hormone replacement therapy or emergency contraception. Continue using your usual contraception while taking Norethisterone.
How Do I Take Norethisterone?
Take one Norethisterone tablet three times a day, starting three days before your period is due, and continue taking it until you want your period to begin again. Your period should typically start within two to three days after stopping the tablets. Do not take Norethisterone if you are pregnant. Food and alcohol do not affect its absorption or effectiveness.
How Can I Delay My Period?
There are no non-medical methods for delaying your period. If you are on the combined contraceptive pill, you may delay your period by running two packs together without the usual break. However, if you're not on the pill, Norethisterone is your best option. It should not be used by women who already take the pill to delay their period. Always consult your GP before using Norethisterone for period delay.
How to Stop Your Period with Norethisterone
To delay your period, take one tablet three times a day, starting three days before your period is due. Continue until you wish your period to begin again. Your period should occur within two to three days after stopping the tablets. Do not use Norethisterone to stop a period that has already started.
If you miss a dose, take it as soon as you remember, unless it’s almost time for your next dose, in which case skip the missed dose. Missing a dose may cause light bleeding or spotting, so it’s a good idea to keep panty liners on hand.
