Good morning. I am a doctor. I would like to ask Dear Pharmacists about the issue of such a prescription: Rp. Bismuthi subnitrici 0,8 M.f.plv. d.t.d. No 40 d.s. 1 to 2 x 1 powder Pharmacies either refuse to fill such a prescription or, despite entering the R fee, they want to count on 100%. They argue that from the release of FP V to the current FP XIII, the use/dosage for external use is given. No oral doses. The last time oral doses were administered was in FP IV. Does this entitle pharmacies to refuse to fill such a prescription or to fulfill it with a 100% payment? After all, until 2007. GASTRO tabl was available. with alkaline bismuth nitrate, and at that time FP VI was in force, in which only external dosage was already given. After all, other ingredients included in FP IV for the last time, e.g. Tinct, are also used in the pharmacy recipe. Convallariae titrata. Is it interpreted arbitrarily? Why do some pharmacies make these powders with Bismuthum subnitricum for my patients, others do not. Some count on R, others on 100%. Are there any regulations that discredit the oral dosage last given in FP IV? Please give me your opinion. W.M.
