[Pharmaceutical Indication Service in a case of palmar-plantar erythema after amoxicillin and ibuprofen treatment].

Case description: Patient (29 years old) with palmo-plantar erythema, goes to the community pharmacy (FC) requesting a cream to treat atopy.

Evaluation: The patient accessed the Pharmaceutical Indication Service (SPIF), showing that the manifestations appeared 24 hours after the start of dental treatment with amoxicillin 1g/12h and ibuprofen 600 mg/8h without any concomitant medication.

Intervention: After explaining the possible relationship of the symptoms with their medication, patient was derived to the doctor with the referral report completed by SEFAC-eXPERT.

Results: The patient went to the emergency where she was treated with intravenous corticosteroid and a prescription for cetirizine 10 mg. The dentist changed the beta-lactam to a macrolide (azithromycin) and the ibuprofen to paracetamol. From the FC, the evolution of the symptoms was monitored, which took 72 hours to disappear. Allergy tests suggested avoiding beta-lactams, cephalosporins, and arylpropionics without being conclusive. Months later, the patient suffered similar symptoms after inhaling a disinfectant spray and the allergy diagnosis was confirmed.

Conclusions: The FC identified and immediately referred using SPIF a case of hypersensitivity in a patient susceptible to RNM and the SPIF helps to record the intervention and follow-up, increasing patient safety.
