Hyperkalemia is a potentially life threatening problem which can lead to cardiac dysrhythmias and death. Drug interactions inducing hyperkalemia are extremely common such as the combination of ACE inhibitors and spironolactone or ACE inhibitors and trimehoprim sulfamethoxazole. Hyperkalemia can also occur with a single agent and is a relatively common complication of therapy with trimethoprim sulfamethoxazole. The following drugs can cause hyperkalemia:
- Ace inhibitors
- Beta blockers
- Cyclosporine
- Digitalis
- Non-steroidal Anti-inflammatory Drugs
- Pentamidine
- Potassium supplement
- Succinylcholine
- Tacrolimus
- Trimethoprim sulfamethoxazole
