Moderate

Ascorbic acid (vitamin C) (applies to Vitamin C) kidney stones

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Nephrolithiasis

Large doses of ascorbic acid have lead to hyperoxaluria in 5% of patients. Ascorbic acid can acidify urine resulting in precipitation of urate, cystine, or oxalate stones. Ascorbic acid should be administered cautiously and dosages modified in patients predisposed to renal stones. Clinical monitoring of urinalysis for pH and crystal formation is recommended.

Moderate

Ascorbic acid (vitamin C) (applies to Vitamin C) sodium

Moderate Potential Hazard, Low plausibility. Applicable conditions: Hypernatremia, Hypertension

Ascorbic acid preparations contain sodium. The sodium content should be considered when used in patients with sodium restricted diets and conditions require sodium restriction, such as congestive heart failure, hypertension, and fluid retention.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
