Safety
Designed for patient tolerability with minimal GI adverse effects1
Most common (≥1/100 to <1/10) adverse reactions observed in clinical studies were mild-to-moderate and generally resolved spontaneously or with treatment1
- Consipation 6.2%
- Hypomagnesemia* 5.3%
- Diarrhoea 3.0%
- Abdominal pain 2.9%
- Flatulance 1.8%
Uncommon adverse reactions (≥1/1,000 to <1/100) included nausea/vomiting1

Hypokalemia has not been identified as an ADR for Veltassa®1,2†

No dose-related oedema observed in over 52 weeks of treatment3
Veltassa® has few known drug-drug interactions1

- Concomitant administration of Veltassa® showed reduced bioavailability of only 3 drugs:1,4
- Ciprofloxacin
- Levothyroxine
- Metformin§
- No interaction was found with administration of oral drugs at least 3 hours apart from Veltassa®1
- Quinidine showed a potential drug interaction in vitro1

- As a precautionary measure, administration of Veltassa® should therefore be separated by at least 3 hours from other oral medicinal products1
With Veltassa® there is no additional CV or renal risk due to sodium1,5,6
Excess sodium intake is associated with increased CV and renal risks:6–17

Increased blood pressure7–9

Decreased renoprotective benefits of RAASi medication14–16**

CV morbidity and mortality7,10–13

Increased oedema risk17

Increased albuminuria6,9
When RAASi are working to decrease Na+, Veltassa® binds K+ without Na+ release1,18

Footnotes
*Hypomagnesaemia was mild-to-moderate, with no patient developing a serum magnesium level <1 mg/dL (0.4 mmol/L). Serum magnesium should be monitored for at least 1 month after initiating treatment, and magnesium supplementation considered in patients who develop low serum magnesium levels.1
†Since excessive doses of Veltassa® may result in hypokalemia, serum potassium levels should be monitored when initiated and uptitrated.1
§Effect of concomitant administration of Veltassa® with metformin is similar to taking metformin with food.4
**In a post hoc analysis of the RENAAL and IDNT trials, treatment effects of angiotensin receptor blockers on renal and cardiovascular outcomes were compared in subgroups of 1,177 patients with type 2 diabetes, nephropathy, and protein urea. Patients with available 24-h urinary sodium measurements were assessed over a 30-month follow-up period. The subgroups, based on dietary sodium intake were: low sodium intake: Na:Cr≤121mmol/g; medium sodium intake: Na:Cr121–≤153 mmol/g; high sodium intake: Na:Cr. The renal outcome in this analysis was defined as a composite of a confirmed doubling of serum creatinine from baseline or end-stage renal disease. The latter was defined as the need for chronic dialysis or renal transplantation. An additional definition for end-stage renal disease of a serum creatinine ≥6mg/dl (≥530μmol/l) applied in the IDNT trial. Compared to non-RAASi, the trend in risk for renal events was significantly reduced by 43%, not changed, or increased by 37% for each tertile of increased sodium intake.14
