Benemid (probenecid) Disease Interactions
There are 5 disease interactions with Benemid (probenecid):
Probenecid (Includes Benemid) ↔ Blood Dyscrasias
Severe Potential Hazard, Moderate plausibility
Applies to: Anemia, Bone Marrow Depression/Low Blood Counts
The manufacturer does not recommend the use of probenecid in patients with known blood dyscrasias. Aplastic anemia, leukopenia, hemolytic anemia and other anemia have been reported infrequently during administration of probenecid. Glucose-6-phosphate dehydrogenase (G-6-PD) deficiency may increase the risk of probenecid-induced hemolytic anemia.

Probenecid (Includes Benemid) ↔ Dehydration
Severe Potential Hazard, High plausibility
Applies to: Dehydration, Diarrhea, Vomiting
Probenecid may promote lithiasis by increasing uric acid concentration in the renal tubules. Adequate hydration is necessary during therapy. Patients who are dehydrated (e.g., due to severe diarrhea or vomiting) may be at increased risk for the development of uric acid kidney stones and should be encouraged to consume additional amounts of liquid or given intravenous fluid. In general, fluid intake sufficient to yield a daily urinary output of at least 2 liters is recommended. Maintenance of a slightly alkaline or neutral urine is also desirable.

Probenecid (Includes Benemid) ↔ Uric Acid Nephrolithiasis
Severe Potential Hazard, High plausibility
Applies to: Uric Acid Nephrolithiasis, History - Nephrolithiasis, Gouty Nephropathy
The use of probenecid is not recommended in patients with a history of uric acid nephrolithiasis or a urinary urate excretion greater than 750 mg/24 hr. Probenecid may promote lithiasis by increasing uric acid concentration in the renal tubules. Adequate hydration is necessary during treatment. In general, a fluid intake sufficient to yield a daily urinary output of at least 2 liters is recommended. Maintenance of a slightly alkaline urine is also desirable.

Probenecid (Includes Benemid) ↔ Pud
Moderate Potential Hazard, Low plausibility
Applies to: Peptic Ulcer, History - Peptic Ulcer
The manufacturer states that probenecid should be used with caution in patients with a history of peptic ulcer. Uricosuric agents can cause upper gastrointestinal irritation and aggravate or reactivate peptic ulcer. However, these effects have primarily been reported with another uricosuric agent, sulfinpyrazone. GI effects associated with probenecid are usually limited to nausea, vomiting, and anorexia.

Probenecid (Includes Benemid) ↔ Renal Dysfunction
Moderate Potential Hazard, High plausibility
Applies to: Renal Dysfunction
Probenecid may not be effective in patients with chronic renal insufficiency, particularly when glomerular filtration rate is 30 mL/min or less. Probenecid has been used in patients with some renal impairment but dosage requirements may be increased.

Drug Interaction Classification
The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
| 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. |
