Drug interactions
Moderate drug interactions
Moderate:
hydrocortisone ophthalmic nelfinavir
Applies to: chloramphenicol / hydrocortisone / polymyxin b ophthalmic and nelfinavir
Nelfinavir may increase the blood levels of hydrocortisone ophthalmic. You may be more likely to experience side effects such as swelling, weight gain, high blood pressure, high blood glucose, muscle weakness, depression, acne, thinning skin, stretch marks, easy bruising, bone density loss, cataracts, menstrual irregularities, excessive growth of facial or body hair, and abnormal distribution of body fat, especially in the face, neck, back, and waist. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Other side effects that may occur include decreased ability to fight infections, increased risk of developing infections, and inadequate response to stress such as infection, surgery, trauma, or a severe asthma attack. Children may experience a reduced growth rate due to excessive effects of hydrocortisone ophthalmic. 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
9 potential interactions Applies to: 9 conditions, including Eye Conditions, Diabetes Mellitus, Cataract, Liver Disease, and Glaucoma/Intraocular Hypertension.
Abnormal Glucose Tolerance
Moderate:
nelfinavir
Nelfinavir has a moderate potential interaction with Abnormal Glucose Tolerance.
New onset diabetes mellitus, exacerbation of preexisting diabetes mellitus, hyperglycemia, and some cases of diabetic ketoacidosis have been reported during postmarketing surveillance in HIV-infected patients treated with protease inhibitors. Some patients required either initiation or dosage adjustments of insulin or oral hypoglycemic agents for treatment of these events. In some cases, hyperglycemia persisted despite discontinuation of protease inhibitor therapy. A causal relationship has not been established between protease inhibitor therapy and these events. Monitoring patients for hyperglycemia, new onset diabetes mellitus, or exacerbation of diabetes mellitus should be considered during protease inhibitor therapy.
Bone Marrow Depression/Low Blood Counts
Major:
chloramphenicol / hydrocortisone / polymyxin b ophthalmic
The chloramphenicol ophthalmic in chloramphenicol / hydrocortisone / polymyxin b ophthalmic has a major potential interaction with Bone Marrow Depression/Low Blood Counts.
Chloramphenicol may cause bone marrow depression and other hematologic toxicities, which can be irreversible or reversible. The former type is independent of dose and results in aplastic anemia with a high rate of mortality, generally from hemorrhage or infection. It has been reported following both systemic and topical administration of chloramphenicol and has an estimated incidence of 1 in 25,000 to 1 in 40,000 courses of therapy. Bone marrow aplasia or hypoplasia may occur after a single dose but more often develops weeks or months after the drug has been discontinued. A reversible myelosuppression occurs much more frequently and is characterized by anemia, vacuolation of red blood cells, decreased reticulocyte count, leukopenia, thrombocytopenia, increased serum iron concentrations, and increased serum iron-binding capacity. It is dose-dependent, occurring regularly at chloramphenicol dosages exceeding 4 g/day (in adults) or at plasma drug concentrations >= 25 mcg/mL, and usually responds to withdrawal of the drug. Therapy with chloramphenicol should be administered cautiously, if at all, in patients with preexisting blood dyscrasias and/or bone marrow depression. Complete blood counts and differential reticulocyte counts should be performed in all patients prior to initiating therapy and approximately every 2 days during therapy. Marked depression of blood counts and/or development of other hematologic abnormalities may be indication for withdrawal of chloramphenicol therapy.
Cataract
Major:
chloramphenicol / hydrocortisone / polymyxin b ophthalmic
The hydrocortisone ophthalmic in chloramphenicol / hydrocortisone / polymyxin b ophthalmic has a major potential interaction with Cataract.
Prolonged use of corticosteroids may cause posterior subcapsular cataracts and elevated intraocular pressure, the latter of which may lead to glaucoma and/or damage to the optic nerves. Therapy with ophthalmic corticosteroids should be administered cautiously in patients with a history of cataracts, glaucoma, or increased intraocular pressure. If these agents are used for more than 10 days, the manufacturers recommend that intraocular pressure be routinely monitored, including in children. The equatorial and posterior subcapsular portions of the lens should be examined for changes.
Coagulation Defects and Disorders
Moderate:
nelfinavir
Nelfinavir has a moderate potential interaction with Coagulation Defects and Disorders.
There have been reports of increased bleeding, including spontaneous skin hematomas and hemarthrosis, in patients with hemophilia type A and B treated with protease inhibitors; however, a causal relationship has not been established. In some patients, additional factor VIII was given. In more than half of the reported cases, protease inhibitor therapy was continued or reintroduced. Patients with hemophilia or other coagulation defects should be monitored closely for bleeding during protease inhibitor therapy.
Diabetes Mellitus
Moderate:
nelfinavir
Nelfinavir has a moderate potential interaction with Diabetes Mellitus.
New onset diabetes mellitus, exacerbation of preexisting diabetes mellitus, hyperglycemia, and some cases of diabetic ketoacidosis have been reported during postmarketing surveillance in HIV-infected patients treated with protease inhibitors. Some patients required either initiation or dosage adjustments of insulin or oral hypoglycemic agents for treatment of these events. In some cases, hyperglycemia persisted despite discontinuation of protease inhibitor therapy. A causal relationship has not been established between protease inhibitor therapy and these events. Monitoring patients for hyperglycemia, new onset diabetes mellitus, or exacerbation of diabetes mellitus should be considered during protease inhibitor therapy.
Eye Conditions
Major:
chloramphenicol / hydrocortisone / polymyxin b ophthalmic
The hydrocortisone ophthalmic in chloramphenicol / hydrocortisone / polymyxin b ophthalmic has a major potential interaction with Eye Conditions.
The use of ophthalmic corticosteroids is contraindicated in most viral diseases of the cornea and conjunctiva, including epithelial herpes simplex keratitis (dendritic keratitis), vaccinia, and varicella; fungal diseases of ocular structures; mycobacterial infections, including tuberculosis, of the eye; and any acute, purulent, untreated ocular infections. Corticosteroids may decrease host resistance to infectious agents, thus prolonging the course and/or exacerbating the severity of the infection while encouraging the development of new or secondary infection. In addition, administration of ophthalmic corticosteroids in severe ocular disease, especially acute herpes simplex keratitis, may lead to excessive corneal and scleral thinning, increasing the risk for perforation. In less serious ocular infections, therapy with ophthalmic corticosteroids may be administered but only with caution and accompanied by appropriate antimicrobial agents. Besides compromising host immune response, corticosteroids may also mask the symptoms of infection, thus hindering the recognition of potential ineffectiveness of the antibiotic therapy. If infection does not improve or becomes worse during administration of an ophthalmic corticosteroid, the drug should be discontinued and other appropriate therapy initiated.
Glaucoma/Intraocular Hypertension
Major:
chloramphenicol / hydrocortisone / polymyxin b ophthalmic
The hydrocortisone ophthalmic in chloramphenicol / hydrocortisone / polymyxin b ophthalmic has a major potential interaction with Glaucoma/Intraocular Hypertension.
Prolonged use of corticosteroids may cause posterior subcapsular cataracts and elevated intraocular pressure, the latter of which may lead to glaucoma and/or damage to the optic nerves. Therapy with ophthalmic corticosteroids should be administered cautiously in patients with a history of cataracts, glaucoma, or increased intraocular pressure. If these agents are used for more than 10 days, the manufacturers recommend that intraocular pressure be routinely monitored, including in children. The equatorial and posterior subcapsular portions of the lens should be examined for changes.
Liver Disease
Moderate:
nelfinavir
Nelfinavir has a moderate potential interaction with Liver Disease.
Nelfinavir is primarily metabolized by the liver. Patients with liver disease may be at greater risk for adverse effects from nelfinavir due to decreased drug clearance. Therapy with nelfinavir should be administered cautiously in patients with liver disease.
Phenylketonuria
Moderate:
nelfinavir
Nelfinavir has a moderate potential interaction with Phenylketonuria.
Viracept (brand of nelfinavir) oral powder contains 11.2 mg of phenylalanine per each gram of powder. The phenylalanine content should be considered when this product is used in patients who must restrict their intake of phenylalanine (i.e. phenylketonurics).
