Drug interactions
Moderate drug interactions
Moderate:
pentamidine lansoprazole
Applies to: pentamidine and lansoprazole
Chronic use of drugs known as proton pump inhibitors including lansoprazole can sometimes cause hypomagnesemia (low blood levels of magnesium), and the risk may be further increased when combined with other medications that also have this effect such as pentamidine.
In severe cases, hypomagnesemia can lead to:
- irregular heart rhythm
- palpitations
- muscle spasm
- tremor
- seizures
In children, abnormal heart rhythm may cause:
- fatigue
- upset stomach
- dizziness
- lightheadedness
A dose adjustment or more frequent monitoring by the doctor may be required to safely use both medications.
If you are using an over-the-counter proton pump inhibitor medication such as Prilosec OTC, Zegerid OTC or Prevacid 24 HR, you should follow the directions on the package carefully. Do not use the medication more frequently or for a longer period than recommended on the label unless otherwise prescribed by your doctor.
It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Disease interactions
34 potential interactions Applies to: 21 conditions, including High Cholesterol, Asthma, Osteoporosis, COPD, and Diarrhea.
Abnormal Glucose Tolerance
Major:
pentamidine
Pentamidine has a major potential interaction with Abnormal Glucose Tolerance.
Pentamidine may have direct toxic effects on beta cells of the pancreas. Hypoglycemia, which may be severe and/or prolonged, as well as hyperglycemia and insulin-dependent diabetes mellitus, the latter of which may be irreversible, have been reported. The onset of pentamidine-induced hypoglycemia generally varied from 5 to 7 days after start of therapy to several days after therapy stops. In some cases, hyperglycemia and progression to diabetes followed, although these effects have occurred independently also. Pancreatic toxicity has been reported with both parenteral use and, less frequently, oral inhalation of pentamidine. The risk appears to be related to total cumulative dosage and prior therapy with the drug, particularly within the last 3 months. Therapy with pentamidine, regardless of route of administration, should be administered cautiously in patients with or predisposed to diabetes or spontaneous hypoglycemia. Blood glucose should be monitored more closely during and for some time after pentamidine therapy.
Alcoholism
Major:
pentamidine
Pentamidine has a major potential interaction with Alcoholism.
Acute and potentially fatal pancreatitis has been reported with parenteral use and, rarely, oral inhalation of pentamidine. Patients with a history of or known risk factors for pancreatitis, such as alcohol abuse or hypertriglyceridemia, should be monitored closely during therapy with pentamidine. Therapy should be discontinued at the first signs or symptoms suggestive of pancreatitis (e.g., nausea, vomiting, abdominal pain, hyperamylasemia with dysglycemia, rising triglycerides, decreasing serum calcium), and preferably permanently discontinued if clinical pancreatitis develops.
Asthma
Moderate:
pentamidine
Pentamidine has a moderate potential interaction with Asthma.
Orally inhaled pentamidine may induce bronchospasm and cough. Therapy with aerosolized pentamidine should be administered cautiously in patients with severe bronchospastic disease or a history of extensive smoking. Pretreatment with a beta-2 adrenergic bronchodilator prior to each dose of aerosolized pentamidine may be helpful in patients who experience respiratory symptoms from the medication.
Bone Marrow Depression/Low Blood Counts
Major:
pentamidine
Pentamidine has a major potential interaction with Bone Marrow Depression/Low Blood Counts.
Hematologic toxicities have been associated occasionally with the parenteral use of pentamidine. Leukopenia and, less frequently, thrombocytopenia have been reported and may be severe (e.g., leukocyte count < 1000/mm3, platelet count < 20,000/mm3). Anemia, neutropenia, pancytopenia, and prolonged clotting time have occurred rarely. Therapy with pentamidine should be administered cautiously in patients with preexisting blood dyscrasias and/or bone marrow depression. Complete blood counts, including platelets, should be performed prior to and periodically during and after therapy. Marked depression of blood counts may be indication for withdrawal of pentamidine therapy.
Major:
pentamidine
Pentamidine has a major potential interaction with Bone Marrow Depression/Low Blood Counts.
Orally inhaled pentamidine is generally not associated with significant systemic toxicity due to limited absorption from the respiratory tract. However, detectable serum concentrations have been reported in some patients receiving chronic oral inhalation therapy, and systemic adverse effects have occasionally occurred. Therefore, when pentamidine is administered by oral inhalation, clinicians may want to heed the usual warnings and precautions associated with parenteral use of the drug.

Diarrhea
Major:
lansoprazole
Lansoprazole has a major potential interaction with Diarrhea.
Published observational studies suggest that proton pump inhibitor (PPI) use may be associated with an increased risk of Clostridium difficile-associated diarrhea (CDAD), especially in hospitalized patients. This diagnosis should be considered for diarrhea that does not improve. It is recommended that patients should use the lowest dose and shortest duration of PPI therapy appropriate to the condition being treated. Close monitoring is recommended in patients with diarrhea and in those taking antibacterial agents as CDAD has been reported with the use of nearly all these agents. Treatment with antibacterial agents alters the normal flora of the colon, leading to overgrowth of C. difficile. C. difficile produces toxins A and B, which contribute to the development of CDAD. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated.

Major:
pentamidine
Pentamidine has a major potential interaction with Renal Dysfunction.
Parenteral use of pentamidine may be associated with nephrotoxicity, usually evidenced by elevations in BUN or serum creatinine concentrations. Azotemia has also been reported. Although pentamidine-induced nephrotoxicity is generally mild to moderate in severity and reversible following discontinuation of the drug, acute renal failure has occurred occasionally. Limited evidence suggests that nephrotoxicity may occur more frequently in patients with AIDS and may be accompanied by severe, sometimes life-threatening hyperkalemia. Therapy with pentamidine should be administered cautiously in patients with renal impairment. The need for dosage adjustments is uncertain. To minimize the risk of toxicity, patients should be adequately hydrated and use with other nephrotoxic agents should be avoided. Renal function and serum potassium levels should be closely monitored, and the dosing frequency reduced or therapy withdrawn if toxicity develops.
Vomiting
