Table 3 Drugs to avoid if possible in symptom control in heart failure.

Drug	Problem
Non‐steroidal anti‐inflammatory drugs (NSAIDs)	Salt and water retention with risk of decompensation
Steroids	Same as for NSAIDs
Drugs with significant anticholinergic effect, eg, cyclizine and tricyclics antidepressants	Pro‐arrhythmic: avoid unless patient is in the dying phase
Bulking agents such as ispaghula husk	Risk of exacerbating constipation in patients on fluid restriction

General note: be aware of potential of drug interactions with patients on warfarin.
