Tolerance and compliance issues with potassium effervescent tablets
These are the best absorbed and most reliable preparations for potassium replacement.
Many patients report that they are irritant to the gut and some may decline them on these grounds; this can be improved by the use of an antacid such as Gaviscon.
A proton pump inhibitor such as Omeprazole is also often helpful and this can also reduce the loss of acid from the gut if the patient continues to vomit. KayCeeL syrup is an alternative that some patients may prefer.
