Add Dr Pepper to the list of pandemic-induced shortages.

Like toilet paper before it, the popular soda is widely unavailable in some parts of the US. The shortages apply to every flavor, Dr Pepper said in a note on Twitter.

The low inventory is the result of increased demand for the product, according to Keurig Dr Pepper, the company that owns Dr Pepper and other beverage brands.

Sales of the soda have “increased consistently over the last four years,” the company said in a statement to CNN.
