Pills similar to Lizinna, particularly in their oestrogen component, include Brevinor and Norimin.
While Lizinna, Brevinor, and Norimin all contain the same type and dose of oestrogen, Ethinylestradiol 35 micrograms, they differ in their progestogen components. The specific combination of oestrogen and progestogen, along with their respective doses, is crucial in determining the overall profile and suitability of a contraceptive pill for an individual.
Understanding the Similarities and Differences
To illustrate the composition of these pills:
| Brand Name | Oestrogen: Name and Dose (micrograms) | Progestogen: Name and Dose (micrograms) |
|---|---|---|
| Lizinna | Ethinylestradiol 35 | Norgestimate 250 |
| Brevinor | Ethinylestradiol 35 | Norethisterone 500 |
| Norimin | Ethinylestradiol 35 | Norethisterone 1000 (1mg) |
As shown in the table:
- Shared Oestrogen: All three pills contain Ethinylestradiol at a dose of 35 micrograms. This consistent oestrogen component contributes to their similarity.
- Differing Progestogens:
- Lizinna uses Norgestimate 250 micrograms.
- Brevinor uses Norethisterone 500 micrograms.
- Norimin uses Norethisterone 1000 micrograms (which is equivalent to 1mg).
The variation in the progestogen type and dose means that while they share a common oestrogen, their overall hormonal profile, potential side effects, and benefits can differ. It is always recommended to consult a healthcare professional to determine the most appropriate contraceptive for individual needs.
