Drug incompatibilities can compromise the safety and effectiveness of parenteral therapy. However, they have been insufficiently studied in primary care. The present study, therefore, aimed to identify potential incompatibilities in primary care and propose tools to reduce incompatibility risk. Data on patients and drugs were collected from electronic health records. The potential for (in)compatibilities was identified at the level of drug pairs, in accordance with data from three literature sources. A total of 190 patients were included in the study. The median number of prescribed drugs per patient per day was 2.0 (IQR, 1), ranging from 2 to 5. Of 431 drug pairs identified through prescriptions, 106 (24.6%) were compatible, 37 (8.6%) were incompatible, and 288 (66.8%) had unknown compatibility. Among potentially incompatible pairs, 62.2% (23/37) involved intravenous therapy. The drugs most frequently included in potentially incompatible pairs were pantoprazole and diazepam. Several tools have been proposed to reduce the risk of incompatibility: the compatibility table, the pH color system, flushing the intravenous line, and switching intramuscular therapy to oral therapy.
