Alka Seltzer is sodium bicarbonate.

It will alter pH.

'Excessive use of sodium bicarbonate can result in increase acid secretion or systemic alkalosis.'

We can at times get into a bit of a 'pickle' by having more than one doc prescribing, and/or in addition taking over the counter substances.

If you are having gastric distress, there are other options. If you are not seeing a GI, and have gastric issues, perhaps you need to see one....ALSO touch base with your primary. Primary docs, who care for patients that see a lot of different specialists, can not possibly keep track of all the different drugs, tests etc, that the specialists oversee.

We have to keep the primary in the loop.

While it is good to be drinking the fluids with the Alka Seltzer, I am concerned that the sodium bicarb. is doing a dance on your system.

Let the doc know how much of the 'bubbly' you have been taking. You may want to call the doc and speak with his nurse regarding the Alka Seltzer issue....don't expect her to know off hand that it causes this..tell her you have just become aware of this, and wonder if it is necessary to take the allopurinol or if you can come in a few days from now....after stopping the Alka Seltzer.
