The information provided in the above table is for information only. It is important to consult a doctor or nurse before starting any period-delay treatment.

How does Norethisterone work?

Norethisterone works by mimicking the effects of progesterone. It can be used to delay a period. It does this by causing the lining of the womb to stay inside the person taking the medication. The lining is released when the treatment is stopped and the person’s period is due.

How long can I delay my periods?

Click Pharmacy can provide you with 60 tablets. This will delay your period for up to 17 days. If you need to delay your period for less time, you will not need as many tablets. Norethisterone tablets are only for occasional use. You should not use these more than once every three months. Do not use this form of period delay long term.

If you forget to take a dose, take it as soon as you remember. 

Does Norethisterone interact with other drugs?

Before you start any new medication, inform your doctor or pharmacist. They must know about any medication you are taking, have recently taken, or might take. This is because it can affect whether the new medication is appropriate for you.

Norethisterone can interact with other medication. Its effect can change when mixed with the following drugs:

● Epilepsy medication (e.g., phenytoin, carbamazepine)
● Antibiotics (e.g., tetracyclines, rifampicin, co-trimoxazole) 
● Antivirals, used to treat HIV (e.g., ritonavir, nelfinavir)
● Anti-cancer medication
● Herbal medicine containing St John’s wort
● Aminoglutethimide, used to treat Cushing's syndrome
● Ciclosporin, used to suppress the immune system
● Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen
● Medicine to treat high blood pressure

Alternative to Norethisterone

Provera is another way to delay your period. There are some differences between the two medications

Microgynon (the brand name) is another option. It is a combined contraceptive pill. If you want to delay your period, you must take Microgynon for two months. When taking Microgynon to delay your period, you need to take two packs back-to-back. That is, you don’t have a seven-day pill-free period or use your inactive mini pill.


When should I take Norethisterone?

To delay your period, you should take one Norethisterone 5 mg tablet three times a day. Start this medicine at least three days before your period is due. The notes that come with the tablets will tell you how to use them. If needed, you can ask your doctor for more help. You can also contact our expert team at Click Pharmacy.
