Applies to: Triam-A (triamcinolone) and erlotinib
Using erlotinib together with triamcinolone may increase the risk of gastrointestinal perforation, a potentially fatal condition and medical emergency where a hole forms all the way through the stomach or intestine.
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 to safely use both medications.
You should seek immediate medical attention if you experience severe abdominal pain, fever, chills, nausea, and/or vomiting during treatment with these medications.
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.
Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
triamcinolone Food/Lifestyle
Applies to: Triam-A (triamcinolone)
Using triamcinolone together with alcohol or grapefruit may increase the risk of side effects of triamcinolone.
You may want to limit your consumption of grapefruit, grapefruit juice, and/or alcohol during treatment with triamcinolone.
Talk to your doctor if you have any questions or concerns.
You should seek immediate medical attention if you experience any unusual bleeding or bruising, or have other signs and symptoms of bleeding such as:
- dizziness
- lightheadedness
- red or black, tarry stools
- coughing up or vomiting fresh or dried blood that looks like coffee grounds
- severe headache
- weakness
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.
Moderate:
erlotinib Food/Lifestyle
Applies to: erlotinib
Erlotinib should be taken on an empty stomach at least 1 hour before or 2 hours after a meal and at the same time each day unless otherwise directed by your doctor.
You should also avoid grapefruit and grapefruit juice while taking erlotinib. Food and grapefruit juice can increase the absorption of erlotinib from the gastrointestinal tract, which may lead to higher blood levels of the medication and possibly increased side effects.
If you are a smoker, you should try to quit as soon as you can. Cigarette smoking can reduce the blood levels of erlotinib, which may make the medication less effective in treating your cancer. It is best to avoid smoking during erlotinib therapy.
Talk to a healthcare professional if you have any questions or concerns.
If you start smoking or undergo smoking cessation, your doctor may need to adjust your dose of erlotinib.
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.

Therapy with corticosteroids should be administered cautiously in patients with preexisting electrolyte disturbances. Caution is also advised when treating patients with seizure disorders, since electrolyte disturbances may trigger seizure activity.
Infection
Major:
Triam-A
The triamcinolone in Triam-A has a major potential interaction with Infection.
The immunosuppressant and anti-inflammatory effects of corticosteroids, particularly at higher dosages, may reduce resistance to infectious agents, increase the risk of disseminated infections, mask symptoms of infection, and reactivate or exacerbate latent/resolved infections; fatal cases have been reported. Avoid use of corticosteroids in patients with cerebral malaria. Screen patients for active (or history of) infection with tuberculosis, hepatitis, varicella, measles, and amebiasis, especially prior to prolonged treatment. Closely monitor for reactivation of latent infections; chemoprophylaxis may be required. In general, corticosteroids should not be used in patients with active infections, especially systemic fungal infections, unless medically necessary to control drug reactions. However, for corticosteroid-dependent patients who develop a severe or life-threatening infection, continuation of corticosteroid therapy with at least physiologic replacement dosages should be considered, since these patients may have secondary adrenocortical insufficiency. Removal of external steroid during periods of stress may be detrimental to these patients.
Intestinal Anastomoses
Moderate:
Triam-A
The triamcinolone in Triam-A has a moderate potential interaction with Intestinal Anastomoses.

In patients with preexisting-existing hepatic impairment or biliary obstruction with doubling of bilirubin or tripling of transaminases values over baseline, erlotinib therapy should be withhold and therapy should be discontinued in patients whose abnormal liver tests meeting the above criteria do not improve significantly or resolve within three weeks. Withhold erlotinib in patients developing severe renal impairment until renal toxicity is resolved. Monitor renal function and electrolytes, particularly in patients at risk of dehydration. Withhold erlotinib for severe renal toxicity.
Moderate:
Triam-A
The triamcinolone in Triam-A has a moderate potential interaction with Liver Disease.
Corticosteroids are primarily metabolized by the liver and may have enhanced effects in patients with liver disease. Dosage adjustments may be necessary in these patients.
Myasthenia Gravis
Moderate:
Triam-A
The triamcinolone in Triam-A has a moderate potential interaction with Myasthenia Gravis.
Although corticosteroids are commonly used in the treatment of myasthenia gravis to increase muscle strength, these agents should nevertheless be administered with caution in such setting. Patients should be treated in an intensive care unit and receive respiratory support, since muscle strength may markedly decrease initially, particularly with high dosages. Preferably, therapy should begin with relatively low dosages (15 to 25 mg/day of prednisone or equivalent) and be increased stepwise as tolerated (approximately 5 mg/day of prednisone or equivalent at 2- to 3-day intervals until marked clinical improvement or a dosage of 50 mg/day is reached). Improvement may be delayed and gradual. Thus, it is important not to discontinue therapy prematurely.
Myoneural Disorder
Moderate:
Triam-A
The triamcinolone in Triam-A has a moderate potential interaction with Myoneural Disorder.
Toxic myopathy has been observed with the chronic use or the administration of large doses of corticosteroids, often in patients with disorders of neuromuscular transmission such as myasthenia gravis or in patients receiving neuromuscular blocking agents. Fluorinated corticosteroids such as betamethasone, dexamethasone, and triamcinolone appear to cause more severe muscle atrophy and weakness than the nonfluorinated agents. Moreover, multiple-daily doses are more toxic than once-daily or, preferably, alternate-day morning doses. Steroid myopathy is generalized and sometimes accompanied by respiratory weakness and dyspnea. In some cases, it has resulted in quadriparesis. Elevations of creatine kinase (CK) may also occur, albeit infrequently. After withdrawal of corticosteroid therapy, recovery may be slow and incomplete. Therapy with corticosteroids should be administered cautiously in patients with preexisting myopathy or myoneural disorders since these conditions may confound the diagnosis of steroid-induced myopathy. The presence of a normal serum CK level, minimal/no changes of myopathy on electromyography, and type 2 muscle fiber atrophy on biopsy are helpful in suggesting steroid-induced weakness. If steroid myopathy is suspected, a dosage reduction or discontinuation of the steroid should be considered.
Myopathy
Moderate:
Triam-A
The triamcinolone in Triam-A has a moderate potential interaction with Myopathy.
Toxic myopathy has been observed with the chronic use or the administration of large doses of corticosteroids, often in patients with disorders of neuromuscular transmission such as myasthenia gravis or in patients receiving neuromuscular blocking agents.

The presence of a normal serum CK level, minimal/no changes of myopathy on electromyography, and type 2 muscle fiber atrophy on biopsy are helpful in suggesting steroid-induced weakness. If steroid myopathy is suspected, a dosage reduction or discontinuation of the steroid should be considered.
Osteoporosis
Moderate:
Triam-A
The triamcinolone in Triam-A has a moderate potential interaction with Osteoporosis.
Corticosteroids reduce osteoblastic function and inhibit the absorption of intestinal calcium, which can result in bone resorption and bone loss during prolonged therapy. In addition, bone matrix may be affected by the protein-catabolic effects of corticosteroids, especially when given in high dosages or for prolonged periods, leading to aseptic necrosis and fractures. Long-term or high-dose corticosteroid therapy should be administered cautiously and only if necessary in patients with or at risk for osteoporosis. Adverse skeletal effects may be minimized by alternate-day or intermittent administration. Any patient receiving prolonged therapy with the equivalent of 7.5 mg prednisone/day or more are at risk for glucocorticoid-induced osteoporosis and should be managed according to The American College of Rheumatology (ACR) guidelines.
Peptic Ulcer
Moderate:
Triam-A
The triamcinolone in Triam-A has a moderate potential interaction with Peptic Ulcer.
Corticosteroids may cause peptic ulcer disease and gastrointestinal (GI) hemorrhage, usually when given in high dosages or for prolonged periods. However, even conventional dosages may aggravate symptoms in patients with a history of peptic ulcers. Delayed healing of ulcers has also been reported. Therapy with corticosteroids should be avoided or administered cautiously in patients with active or latent peptic ulcers or other risk factors for GI bleeding. Some clinicians recommend the use of prophylactic antacids or H2-antagonists between meals when large doses of corticosteroids are necessary.
Post MI Syndrome
Moderate:
Triam-A
The triamcinolone in Triam-A has a moderate potential interaction with Post MI Syndrome.
The use of corticosteroids may be associated with left ventricular free-wall rupture in patients who have had a recent myocardial infarction. Pharmacologic dosages of corticosteroids should be administered with great caution in such patients.
Prematurity/Underweight in Infancy
Major:
Triam-A
The triamcinolone in Triam-A has a major potential interaction with Prematurity/Underweight in Infancy.
The use of certain parenteral formulations of dexamethasone, hydrocortisone, methylprednisolone, prednisolone and triamcinolone is considered by the drug manufacturers to be contraindicated in neonates, particularly premature infants and infants of low birth weight. Some formulations of these drugs contain benzyl alcohol which, when used in bacteriostatic saline intravascular flush and endotracheal tube lavage solutions, has been associated with fatalities and severe respiratory and metabolic complications in low-birth-weight premature infants. However, many experts feel that, in the absence of benzyl alcohol-free equivalents, the amount of the preservative present in these formulations should not necessarily preclude their use if they are clearly indicated. The American Academy of Pediatrics considers benzyl alcohol in low doses (such as when used as a preservative in some medications) to be safe for newborns. Continuous infusions of high dosages of medications containing benzyl alcohol may, however, cause toxicity and should be avoided if possible.
Psychosis
Moderate:
Triam-A
The triamcinolone in Triam-A has a moderate potential interaction with Psychosis.
Corticosteroids may aggravate the symptoms of psychosis and emotional instability. Patients with these conditions should be monitored for increased or worsened symptoms during corticosteroid therapy.

All corticosteroids also increase excretion of calcium and can cause hypocalcemia. Therapy with corticosteroids should be administered cautiously in patients with preexisting electrolyte disturbances. Caution is also advised when treating patients with seizure disorders, since electrolyte disturbances may trigger seizure activity.
Strongyloidiasis
Moderate:
Triam-A
The triamcinolone in Triam-A has a moderate potential interaction with Strongyloidiasis.
Unlike most helminths, Strongyloides stercoralis has the ability to replicate in the human host. In patients with strongyloidiasis, the use of pharmacologic or immunosuppressive dosages of corticosteroids may result in Strongyloides hyperinfection and dissemination with widespread larval migration, often accompanied by severe enterocolitis and potentially fatal gram-negative septicemia. Therapy with corticosteroids should be administered with extreme caution, if at all, in these patients. For patients on corticosteroids who develop known or suspected Strongyloides infestation, withdrawal of corticosteroids or reduction of the dose of corticosteroids is recommended.
Systemic Sclerosis
Moderate:
Triam-A
The triamcinolone in Triam-A has a moderate potential interaction with Systemic Sclerosis.
In patients with scleroderma, corticosteroids may precipitate renal crisis with malignant hypertension, possibly via steroid-induced increases in renin substrate and angiotensin II levels and decreases in vasodilator prostaglandin production.

In patients with latent tuberculosis or tuberculin reactivity, the use of pharmacologic dosages of corticosteroids may cause a reactivation of the disease. Close monitoring for signs and symptoms of tuberculosis is recommended if corticosteroid therapy is administered to patients with a history of tuberculosis or tuberculin reactivity. During prolonged corticosteroid therapy, tuberculosis chemoprophylaxis may be considered.
Ulcerative Colitis
Moderate:
Triam-A
The triamcinolone in Triam-A has a moderate potential interaction with Ulcerative Colitis.
Corticosteroids may cause gastrointestinal perforation and hemorrhage, usually when given in high dosages or for prolonged periods. They may also mask symptoms of complications such as peritonitis or intraabdominal sepsis. Therapy with corticosteroids should be avoided or administered cautiously in patients with diverticulitis, nonspecific ulcerative colitis (if there is a probability of impending perforation, abscess, or other pyogenic infection), or recent intestinal anastomoses.
Underactive Thyroid
Moderate:
Triam-A
The triamcinolone in Triam-A has a moderate potential interaction with Underactive Thyroid.
Corticosteroids may have enhanced effects in hypothyroidism due to decreased metabolism of these agents. Patients with hypothyroidism should be monitored more closely for excessive cortisol effects. Dosage adjustments may be required secondary to changes in their thyroid condition.
