Medication details


Noriday tablets are an oral contraceptive medication used to prevent pregnancy. They contain norethisterone, a synthetic hormone that stops ovulation and thickens the mucus in the cervix, making it difficult for sperm to reach the egg. This combined action provides effective and reliable protection against pregnancy.

Noriday is a low-dose contraceptive, which means it has fewer side effects compared to other contraceptive methods. Some common side effects may include nausea, headache, and changes in menstrual bleeding patterns. It is important to note that Noriday does not protect against sexually transmitted infections.

It is recommended to consult a doctor before starting to use Noriday tablets. They will be able to discuss the benefits and risks, and determine whether Noriday is the right choice for you. With the proper use of Noriday, women can have peace of mind and reliable protection against pregnancy.


Initiating Noriday: Embark on your Noriday journey on the first day of your menstrual cycle, ideally coinciding with the onset of bleeding.

Daily Regimen: Consume one Noriday tablet daily, ensuring consistency in timing.

Continuous Usage: Embrace uninterrupted usage, eliminating the need for breaks between packs.

Immediate Protection: Noriday guarantees immediate contraceptive protection when initiated on the first day of menstruation. For those commencing at other times, supplementary contraception (condoms) is advisable during the initial seven days.

Missed Doses: In instances of missed doses, guidance is provided in the "What do I do if I forget to take a pill?" section.


Noriday tablets encompass the following elements:
Active Component: 350 micrograms of norethisterone.
Additional Constituents: Maize starch, povidone, magnesium stearate, and lactose monohydrate.
