Walgreens has ended limits it had imposed recently for online purchases of children�s over-the-counter fever reducing products.

The drugstore chain said improved supplies allowed it to lift its restriction of six products. The company had placed no limit on in-store purchases.

Last month both Walgreens and CVS Health restricted purchases of some over-the-counter children�s medicines citing supply issues. CVS Health put a two-product limit on all children�s pain relief products bought through its pharmacies or online.

A CVS Health spokeswoman said Tuesday that limits on some children�s medicines remain in place. She did not offer a time frame for when it might end.

An unusually fast start to the annual U.S. flu season, plus a spike in other respiratory illnesses, created a surge in demand for fever relievers and other products people can buy without a prescription.

Shortages of medicines like Children�s Tylenol developed, varying around the country and sometimes even within communities.

Experts who track medicine shortages said in December that the problem could persist through the winter cold-and-flu season. But they noted that it should not last as long as other recent shortages of baby formula or prescription drugs.
