How to Confirm You're Taking Primolut N (Norethisterone)
To confirm you're taking Primolut N, verify the medication name "Primolut N" or "norethisterone" (also called norethindrone) on your prescription bottle label, cross-reference this with the physical appearance of the tablets, and check the package insert for manufacturer details. 1
Verification Steps Using the "Rights" of Medication Administration
Check Your Prescription Label
- Verify the medication name twice: The pharmacy prescription label should clearly state "Primolut N," "norethisterone," or "norethindrone" (the US name for the same compound). 1
- Confirm the prescriber's order matches: Cross-reference what your doctor prescribed with what appears on the pharmacy label. 1
- Check the expiration date: Ensure the medication has not expired. 1
Identify the Physical Medication
- Examine the tablet markings: Primolut N tablets typically have specific imprints or markings that identify them as norethisterone. 1
- Review the package insert: The manufacturer's information sheet inside the medication box will confirm the active ingredient is norethisterone or norethisterone acetate. 2, 3, 4
- Verify the dosage strength: Primolut N commonly comes in 5 mg tablets, though dosing can vary (norethisterone acetate formulations may use 10 mg doses for certain indications). 2, 4
Cross-Reference with Your Medical Records
- Confirm with your prescriber: If uncertain, contact your healthcare provider to verify they prescribed Primolut N specifically. 1
- Check your medication list: Review your current medication documentation to ensure norethisterone is listed. 1
Important Clinical Context
Understanding Norethisterone Formulations
- Norethisterone (NET) is a synthetic progestogen with very weak androgenic and estrogenic properties. 5
- It is available in multiple formulations including oral tablets (Primolut N), transdermal patches, and as norethisterone acetate (NETA). 3, 4
- The medication is used for various gynecological conditions including abnormal uterine bleeding, endometriosis, and contraception. 4
Common Pitfalls to Avoid
- Don't confuse with combined oral contraceptives: Primolut N contains only progestogen (norethisterone), unlike combined pills that contain both estrogen and progestogen. 1, 6
- Don't assume all progestogen pills are the same: Different progestogens (levonorgestrel, norethisterone, dienogest) have distinct properties and uses. 6, 7
- Verify you're not taking a look-alike medication: Some medications have similar names but different active ingredients. 1
