Turmeric also interacts with diabetes medications, which reduce the blood sugar. Namely, it boosts their effect, and thus elevates the risk of low blood sugar. As a result, you may experience numerous side –effects, like blurred vision, delirium, impaired cognitive function, anxiety, and shakiness.
The consumption of turmeric may also lead to allergic reactions, such as outbreaks like rashes or hives, and may even cause shortness of breath and anaphylaxis.
Furthermore, turmeric should not be combined with drugs that reduce stomach acid, as the body will actually increase its production of stomach acid, and thus, lead to nausea, stomach pain, bloating, and esophagus damage.
These drugs which lower the stomach acid include Omeprazole, Famotidine (Pepcid), Cimetidine (Tagamet), and Ranitidine (Zantac).
Therefore, if you take turmeric at the same time as some drug or medicine, or in case you experience some allergic reaction, you should replace it with some other natural alternative, or reduce the amount of turmeric you consume.
