A population‐based nested case–control study has shown that concurrent use of antiplatelet drugs or selective serotonin reuptake inhibitors with direct-acting oral anticoagulants is associated with nearly 2-fold increased risk of major bleeding leading to hospitalisation. In clinical practice, drugs that increase plasma levels of the DOACs by inhibition of CYP3A4 and/or P‐glycoprotein do not increase the risk of major bleeding.

This review summarises the pharmacological treatment for vertigo in Meniere disease. Evidence supporting the efficacy for betahistine, diuretics, and intratympanic administration of corticosteroids or gentamicin is limited. Treatment should include therapeutic counselling, sodium-free diet, high-water intake, and a diary of vertigo attacks with symptoms during the episodes.

In this meta-analysis of observational studies an increased risk of community-acquired pneumonia (CAP) was identified with low-dose and high-dose PPI use. Use of PPIs for 3-6 months was associated with a twofold risk of developing CAP. There was a statistically significant association between the PPI users and the rate of hospitalization (OR 2.59).

In this USA retrospective cohort study of nearly 7000 Veterans with diabetes more than 40% were potentially overtreated. Treatment deintensification (discontinuation or dose reduction for a consecutive 7‐day period) occurred in less than one‐half of potentially overtreated Veterans and was strongly associated with low HbA1c values and use of medications with high risk for hypoglycaemia (e.g. sulfonylurea).
