Sodium citrate dihydrate is an ingredient commonly found in over-the-counter remedies designed to relieve nausea. This article explains how this compound functions to alleviate feelings of sickness. Understanding its properties and how it interacts with the body can help clarify its role in managing discomfort.
Understanding Sodium Citrate Dihydrate
Sodium citrate dihydrate is a salt derived from citric acid, a compound naturally found in citrus fruits. This compound is highly soluble in water, making it suitable for liquid oral solutions often found in anti-nausea products. As a mild base, sodium citrate acts as a buffering agent, meaning it helps to stabilize pH levels by resisting changes in acidity.
Mechanism of Nausea Relief
Sodium citrate dihydrate primarily works as a local antiemetic, meaning its action targets the gastrointestinal tract rather than the brain’s vomiting center. When ingested, it helps to neutralize excessive stomach acid, which can often irritate the stomach lining. This irritation can trigger nausea signals that are sent to the brain. By reducing stomach acidity, sodium citrate dihydrate soothes this local irritation, thus diminishing the sensation of nausea.
Common Applications for Nausea
Sodium citrate dihydrate is frequently used for nausea associated with an upset or sour stomach. This includes temporary discomfort from overindulgence in food or drink. It is also indicated for mild stomach flu symptoms and can sometimes be used for morning sickness. This compound is effective for mild to moderate forms of nausea that arise from gastrointestinal irritation.
Guidelines for Use
Sodium citrate dihydrate is available as an oral solution or chewable tablets. For liquid forms, dilution in water is often recommended. Dosage varies for adults and children, so follow directions on the product label. Doses can often be repeated after a short interval, but it is important not to exceed the maximum daily amount.
Safety Information and Who Should Avoid It
While well-tolerated, sodium citrate dihydrate can cause mild side effects such as stomach upset, diarrhea, or water retention. Individuals with specific health conditions should avoid using products containing sodium citrate dihydrate. This includes those on sodium-restricted diets, patients with severe kidney impairment, or individuals with heart conditions, due to the sodium content. Some formulations may contain sugars like fructose or dextrose, requiring caution for individuals with diabetes or hereditary fructose intolerance. For persistent or severe nausea, consulting a healthcare professional is advisable.
