Norethisterone 5mg

Buy Norethisterone for Period Delay

Norethisterone works by preventing the lining of the womb from being shed, therefore delaying your period until you stop taking the tablets. You will need to take one Norethisterone tablet three times a day, starting three days before your period is due to commence. Your period will be delayed whilst you are taking the tablets and should start 2 -3 days after you stop taking them. Please note that Norethisterone is for occasional use only. Do not use more than once in 4 months. Please discuss with your doctor if you need to manage your period for longer.

Alternatives

Women looking to delay their period more frequently should consider other methods such as the contraceptive pill. Please discuss this with your regular GP who will assess you for suitability, as the contraceptive pill is only available to order online for patients that have already stabilised on this medication.

Whilst medicines containing the active ingredient norethisterone have become available over the counter recently, you may still wish to have an online doctor consultation to ensure you are taking the correct medication for your needs. As such, Norethisterone tablets are only available with a valid prescrption. Some women decide to use a longer-term solution for managing their periods following a doctor consultation. It is important to also consider your contraception needs when deciding which solution is suitable for you.

Norethisterone tablets are the generic form of medicine containing the active ingredient norethisterone. This is also available under the brand name Primolut N (Bayer). Both contain the same amount of the active ingredient norethisterone and are therefore identical medicines. There are also other treatment options to postpone periods, including medroxyprogesterone acetate, however this is not available online through Anytime Doctor.

Yes, you can get pregnant whilst taking Norethisterone. Norethisterone is not a contraceptive. It is very important that you use alternative methods of contraception such as condoms if you do not intend to get pregnant. Please discuss with your doctor if you are planning to get pregnant and read the advice above (see 'Pregnancy and Breastfeeding' above) and in the patient information leaflet.
