Medicines containing substances known as ergot derivatives can have serious side effects, called fibrosis and ergotism. As a result, they should no longer be used in the EU to treat a number of conditions involving blood circulation problems (that usually affect elderly patients) or problems with memory and sensation, or to prevent migraine headaches, as the risks outweigh the benefits.
This is based on a review of data showing an increased risk of fibrosis (formation of excess connective tissue that can damage organs and body structures) with these medicines.
Fibrosis was most frequently reported with dihydroergotamine, including retroperitoneal, cardiac, pulmonary and pleural fibrosis. There were fewer reports of fibrotic reactions with the other ergot derivatives. The CHMP noted the difficulty of diagnosing fibrosis (due to delayed onset of symptoms) and the probability of under-reporting of fibrotic reactions.
Cases of ergotism or potentially related symptoms were most frequently reported with dihydroergotamine. Patients were young (mean age 41 years old), with a short time to onset after starting dihydroergotamine (less than two months, mean: 2 days). The severity of such adverse effects and their possible fatal outcome was underlined. Several cases of ergotism or symptoms potentially related to ergotism (including severe cases of symptoms of constriction of peripheral blood vessels) were also identified with the other ergot derivatives.
Ergot derivatives are recognised as being capable of inducing fibrosis, in particular heart-valve fibrosis, through serotoninergic-receptor activation, which is extensively described in the literature. The varying affinity for serotoninergic receptors of the different ergot derivatives, and the therapeutic doses used, may explain the differences observed in reporting frequencies for the fibrotic reactions

La vasoconstriction est visiblement plus forte avec le 1P-LSD qu'avec le LSD, même s'il faut garder en tête que les dérivés de l'ergot ont généralement des propriétés vasoconstrictrices* (recherchées et utilisées pour certains types de migraines notamment).
Mais tu n'es pas le seul à rapporter ce type d'effets avec le 1P, quelques exemples parmi d'autres (dans le premier fil sont répertoriés un certain nombres de cas) :

Bref, pour quelqu'un de sensible à ça (problèmes de circulation, cardiaques, tension artérielle), il vaut mieux rester vigilant. J'ai l'impression que le 1cp est un peu moins sévère à ce niveau, bien que des fourmillements (notamment au niveau des chevilles) sont perceptibles même en microdosage.
* Plusieurs cas d'ergotisme ou de symptômes potentiellement liés à l'ergotisme (y compris des cas sévères de symptômes de constriction des vaisseaux sanguins périphériques) ont également été identifiés avec les autres dérivés de l'ergot. Plus de précisions ci-dessous :Anonyme813 a écrit

Salut,
Le truc qui m’étonne, c’est qu’en dehors de la douleur à la poitrine et de la fatigue, je ne ressentais pas de vasoconstriction dans mes membres (bras, jambes etc).
J’avais fait un ECG il y a 3 mois, le docteur m’a pas parlé des résultats alors j’pense que ça doit pas être mauvais...
Merci beaucoup des informations apportés concernant l’ergotisme.
