Disease interactions

11 potential interactions Applies to: 11 conditions, including Allergies, Asthma, Diarrhea, HIV-1 Infection, and Urinary Retention.

Allergies

Major:

Avar

The sulfacetamide sodium topical in Avar has a major potential interaction with Allergies.

Sulfonamides may be systemically absorbed when applied to the skin, eye, or mucosal membranes. The use of sulfonamides is associated with large increases in the risk of Stevens-Johnson syndrome, toxic epidermal necrolysis and other serious dermatologic reactions, although these phenomena are rare as a whole. Hepatitis, pneumonitis, and interstitial nephritis have also occurred in association with sulfonamide hypersensitivity. Therapy with topical sulfonamides should be administered cautiously in patients with severe allergies, bronchial asthma or AIDS, since these patients may be at increased risk for potentially severe hypersensitivity reactions. Patients should be instructed to promptly report signs and symptoms that may precede the onset of cutaneous manifestations of the Stevens-Johnson syndrome, such as high fever, severe headache, stomatitis, conjunctivitis, rhinitis, urethritis, and balanitis. Sulfonamide therapy should be stopped at once if a rash develops.

Asthma

Major:

Avar

The sulfacetamide sodium topical in Avar has a major potential interaction with Asthma.

Sulfonamides may be systemically absorbed when applied to the skin, eye, or mucosal membranes. The use of sulfonamides is associated with large increases in the risk of Stevens-Johnson syndrome, toxic epidermal necrolysis and other serious dermatologic reactions, although these phenomena are rare as a whole. Hepatitis, pneumonitis, and interstitial nephritis have also occurred in association with sulfonamide hypersensitivity. Therapy with topical sulfonamides should be administered cautiously in patients with severe allergies, bronchial asthma or AIDS, since these patients may be at increased risk for potentially severe hypersensitivity reactions. Patients should be instructed to promptly report signs and symptoms that may precede the onset of cutaneous manifestations of the Stevens-Johnson syndrome, such as high fever, severe headache, stomatitis, conjunctivitis, rhinitis, urethritis, and balanitis. Sulfonamide therapy should be stopped at once if a rash develops.

Bone Marrow Depression/Low Blood Counts

Major:

Avar

The sulfacetamide sodium topical in Avar has a major potential interaction with Bone Marrow Depression/Low Blood Counts.

Sulfonamides may be systemically absorbed when applied to the skin, eye, or mucosal membranes. The use of sulfonamides has been associated with hematologic toxicity, including methemoglobinemia, sulfhemoglobinemia, leukopenia, granulocytopenia, eosinophilia, hemolytic anemia, aplastic anemia, purpura, clotting disorder, thrombocytopenia, hypofibrinogenemia, and hypoprothrombinemia. Therapy with topical sulfonamides should be administered cautiously in patients with preexisting blood dyscrasias or bone marrow suppression. Complete blood counts should be obtained regularly during prolonged therapy (>2 weeks), and patients should be instructed to immediately report any signs or symptoms suggestive of blood dyscrasia such as fever, sore throat, local infection, bleeding, pallor, dizziness, or jaundice.

Dehydration

Moderate:

Avar

The sulfacetamide sodium topical in Avar has a moderate potential interaction with Dehydration.

Sulfonamides may be systemically absorbed when applied to the skin, eye, or mucosal membranes. The use of sulfonamides has been associated with crystalluria due to precipitation of the sulfonamide and/or its N4-acetyl metabolite in the urinary tract. Renal toxicity such as uro- and nephrolithiasis, nephritis, toxic nephrosis, hematuria, proteinuria, and elevated BUN and creatinine has been reported. Hydration and adequate urinary output (> 1.5 L/day) should be maintained during sulfonamide administration. Patients who are dehydrated (e.g., due to severe diarrhea or vomiting) may be at increased risk for the development of crystalluria and lithiasis and should be encouraged to consume additional amounts of liquid. Renal function tests and urinalysis should be performed regularly during prolonged therapy (> 2 weeks).

Diarrhea

Moderate:

Avar

The sulfacetamide sodium topical in Avar has a moderate potential interaction with Diarrhea.

Sulfonamides may be systemically absorbed when applied to the skin, eye, or mucosal membranes. The use of sulfonamides has been associated with crystalluria due to precipitation of the sulfonamide and/or its N4-acetyl metabolite in the urinary tract. Renal toxicity such as uro- and nephrolithiasis, nephritis, toxic nephrosis, hematuria, proteinuria, and elevated BUN and creatinine has been reported. Hydration and adequate urinary output (> 1.5 L/day) should be maintained during sulfonamide administration. Patients who are dehydrated (e.g., due to severe diarrhea or vomiting) may be at increased risk for the development of crystalluria and lithiasis and should be encouraged to consume additional amounts of liquid. Renal function tests and urinalysis should be performed regularly during prolonged therapy (> 2 weeks).

HIV-1 Infection

Major:

Avar

The sulfacetamide sodium topical in Avar has a major potential interaction with HIV-1 Infection.

Sulfonamides may be systemically absorbed when applied to the skin, eye, or mucosal membranes. The use of sulfonamides is associated with large increases in the risk of Stevens-Johnson syndrome, toxic epidermal necrolysis and other serious dermatologic reactions, although these phenomena are rare as a whole. Hepatitis, pneumonitis, and interstitial nephritis have also occurred in association with sulfonamide hypersensitivity. Therapy with topical sulfonamides should be administered cautiously in patients with severe allergies, bronchial asthma or AIDS, since these patients may be at increased risk for potentially severe hypersensitivity reactions. Patients should be instructed to promptly report signs and symptoms that may precede the onset of cutaneous manifestations of the Stevens-Johnson syndrome, such as high fever, severe headache, stomatitis, conjunctivitis, rhinitis, urethritis, and balanitis. Sulfonamide therapy should be stopped at once if a rash develops.

Liver Disease

Moderate:

Avar

The sulfacetamide sodium topical in Avar has a moderate potential interaction with Liver Disease.

Sulfonamides may be systemically absorbed when applied to the skin, eye, or mucosal membranes. Hepatotoxicity, including jaundice, diffuse hepatocellular necrosis, hypersensitivity hepatitis and hepatic failure, has rarely been reported in patients receiving sulfonamides. In addition, sulfonamides are partially metabolized by the liver and may accumulate in patients with hepatic impairment. Therapy with topical sulfonamides should be administered cautiously in patients with liver disease.

Porphyria

Major:

Avar

The sulfacetamide sodium topical in Avar has a major potential interaction with Porphyria.

Sulfonamides may be systemically absorbed when applied to the skin, eye, or mucosal membranes. Therapy with topical sulfonamides should be administered cautiously in patients with porphyria, since these drugs can precipitate an acute attack. The use of oral sulfonamides is considered contraindicated in patients with porphyria.

Renal Dysfunction

Moderate:

Avar

The sulfacetamide sodium topical in Avar has a moderate potential interaction with Renal Dysfunction.

Sulfonamides may be systemically absorbed when applied to the skin, eye, or mucosal membranes. Once absorbed, sulfonamides and their metabolites are eliminated by the kidney. Patients with renal impairment may be at greater risk for adverse effects from sulfonamides due to decreased drug clearance. Additionally, sulfonamides may cause renal toxicity secondary to crystalluria, including uro- and nephrolithiasis, nephritis, toxic nephrosis, hematuria, proteinuria, and elevated BUN and creatinine. Hydration and adequate urinary output (> 1.5 L/day) should be maintained during sulfonamide administration. Renal function tests and urinalysis should be performed regularly during prolonged therapy (> 2 weeks). Some manufacturers of topical sulfonamide products do not recommend their use in patients with impaired renal function.

Urinary Retention

Moderate:

Avar

The sulfacetamide sodium topical in Avar has a moderate potential interaction with Urinary Retention.

Sulfonamides may be systemically absorbed when applied to the skin, eye, or mucosal membranes. Once absorbed, sulfonamides are excreted and concentrated in the urine. Therapy with topical sulfonamides should be administered cautiously in patients with urinary obstruction or retention, since excessive drug accumulation may occur. These patients may also be at increased risk for sulfonamide crystalluria, which may be associated with renal toxicity such as uro- and nephrolithiasis, nephritis, toxic nephrosis, hematuria, proteinuria, and elevated BUN and creatinine. A urinary output of at least 1.5 L/day should be maintained during sulfonamide administration. Renal function tests and urinalysis should be performed regularly during prolonged therapy (> 2 weeks).

Vomiting

Moderate:

Avar

The sulfacetamide sodium topical in Avar has a moderate potential interaction with Vomiting.

Sulfonamides may be systemically absorbed when applied to the skin, eye, or mucosal membranes. The use of sulfonamides has been associated with crystalluria due to precipitation of the sulfonamide and/or its N4-acetyl metabolite in the urinary tract. Renal toxicity such as uro- and nephrolithiasis, nephritis, toxic nephrosis, hematuria, proteinuria, and elevated BUN and creatinine has been reported. Hydration and adequate urinary output (> 1.5 L/day) should be maintained during sulfonamide administration. Patients who are dehydrated (e.g., due to severe diarrhea or vomiting) may be at increased risk for the development of crystalluria and lithiasis and should be encouraged to consume additional amounts of liquid. Renal function tests and urinalysis should be performed regularly during prolonged therapy (> 2 weeks).
