Yes, the cylindrical bottles (white cap) and the conical bottles (turquoise cap) with an orange square and lot numbers starting with 7 have been manufactured by the manufacturing site in Drogenbos, Belgium, (BMB) owned by Besins until 2012 when it was sold to Delpharm and recently re-acquired by Besins due to the shortages (https://manufacturingchemist.com/news/article_page/Besins_acquires_site_in_Belgium_to_prevent_HRT_supply_line_issues/201902)
The conical bottles with a green square and lot numbers starting with 1 have been manufactured in Montrouge, France by Laboratoires Besins International (LBI), in a frustrated attempt to relocate gel production to France.
This manufacturing site had been producing solely Androgel (testosterone) for the US market and probably Oestrodose for the French market, and currently only opens during weekends (check on Google).
Some women started HRT on the green square bottles and felt fine because they had never used the other one, but some women felt the difference if they had been on the orange square bottles.
I have already mentioned earlier on this thread the reason why the gels could be different despite having the same formulation. The suppliers of the ingredients are probably different because Belgium and France are different countries under different laws.
I also suspect that the Delpharm team had the experience and expertise to produce different batches within more consistent parameters, while the Besins team is still acquiring those skills.
In short, the 'new' cylindrical bottles with a white cap and lot numbers starting with 7 are not the same as the 'old' cylindrical bottles, in the sense that the gel inside them has been manufactured by the Besins team, not the Delpharm team.
The bottles and pumps have different manufacturers as well. The cylindrical (white cap) are manufactured by Lablabo and the conical (turquoise cap) are manufactured by Rexam (currently called Nemera).
You can check this on the MHRA product site by serching Oestrogeln and ticking the disclaimer box.
Tere are 3 different leaflets for the 'official' product (Oestrogel sold and distibuted by Besins in the UK).
All 3 leaflets have the code PL (Product Licence) while the ones imported by other distributors have the code PLPI (Product Licence Parallel Import).
The 3 PIL (Patient Information Leaflets) for the Oestrogel PL are labeled:
- Proposed Leaflet-PIL-Oestrogel-BMB-Lablabo
- Proposed Leaflet-PIL-Oestrogel-BMB-Rexam
- Proposed Leaflet-PIL-Oestrogel-LBI-Rexam
Number 1 is the cylindrical bottle (white cap), number 2 is the conical bottle (turquoise cap) with an orange square and number 3 is the conical bottle (turquoise cap) with a green square.
I suspect Besins is dedicating the Drogenbos site to the manufacturing of Oestrogel from now on and hopefullly the batches will be more consistent.
Until then, all we can do is tweak the dose (for some women, also the dosage) until we find that sweet spot where most symptoms are being controlled, but since we can't anticipate which of the 3 currently available versions we will be given, I would recommend you talk to your chemist to request/stock always the same version, whether it's the cylindrical (white cap) bottle or the conical (turquoise cap) with an orange square.
The green square version is probably not going to be available for a long time in the UK; I suspect the Montrouge manufacturing site is either idle or only producing Oestrodose for the French market.
Remember that many distributors in the UK will acquire Oestrodose or Oestrogel from European countries to sell them in the UK as parallel imports, but that doesn't mean the product is different, only that they might be manufactured in Montrouge, i.e. the green square version.
Hope this helps!
