Interactions between your drugs

Moderate

buPROPion caffeine

Applies to: Wellbutrin XL (bupropion) and aspirin / caffeine / salicylamide

MONITOR: Additive or synergistic effects on blood pressure may occur when bupropion is combined with sympathomimetic agents such as nasal decongestants, adrenergic bronchodilators, ophthalmic vasoconstrictors, and systemic vasopressors. Treatment with bupropion can result in elevated blood pressure and hypertension. In clinical practice, hypertension, in some cases severe and requiring acute treatment, has been observed in patients receiving bupropion alone and in combination with nicotine replacement therapy. These events have occurred in both patients with and without evidence of preexisting hypertension. Furthermore, postmarketing cases of hypertensive crisis have been reported during the initial titration phase with bupropion-naltrexone treatment.

MANAGEMENT: Caution is advised when bupropion is used with other drugs that increase dopaminergic or noradrenergic activity due to an increased risk of hypertension. Blood pressure and heart rate should be measured prior to initiating bupropion therapy and monitored at regular intervals consistent with usual clinical practice, particularly in patients with preexisting hypertension. Dose reduction or discontinuation of bupropion should be considered in patients who experience clinically significant and sustained increases in blood pressure or heart rate.

aspirin salicylamide

Applies to: aspirin / caffeine / salicylamide and aspirin / caffeine / salicylamide

MONITOR: The combined use of low-dose or high-dose aspirin with other nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the potential for serious gastrointestinal (GI) toxicity, including inflammation, bleeding, ulceration, and perforation. Aspirin at anti-inflammatory dosages or higher may also decrease the plasma concentrations of many NSAIDs. The decreases have ranged from none or small (piroxicam, meloxicam, naproxen, tolmetin) to substantial (flurbiprofen, ibuprofen). However, the therapeutic response does not appear to be affected. Investigators theorize that aspirin may displace NSAIDs from plasma protein binding sites, resulting in increased concentration of unbound, or free, drug available for clearance. The increase in NSAID free fraction, and possibly some contributory anti-inflammatory effect from aspirin, may account for the lack of overall effect on therapeutic response.

MANAGEMENT: Caution is advised if aspirin, particularly at anti-inflammatory dosages, is used with other NSAIDs. Concomitant administration of NSAIDs is considered contraindicated or not recommended with aspirin at analgesic/anti-inflammatory dosages by many NSAID manufacturers. During concomitant therapy, patients should be advised to take the medications with food and to immediately report signs and symptoms of GI ulceration and bleeding such as abdominal pain, bloating, sudden dizziness or lightheadedness, nausea, vomiting, hematemesis, anorexia, and melena.

aspirin caffeine

Applies to: aspirin / caffeine / salicylamide and aspirin / caffeine / salicylamide

One study has reported that coadministration of caffeine and aspirin lead to a 25% increase in the rate of appearance and 17% increase in maximum concentration of salicylate in the plasma. A significantly higher area under the plasma concentration time curve of salicylate was also reported when both drugs were administered together. The exact mechanism of this interaction has not been specified. Physicians and patients should be aware that coadministration of aspirin and caffeine may lead to higher salicylate levels faster.

Drug and food interactions

Moderate

buPROPion food

Applies to: Wellbutrin XL (bupropion)

GENERALLY AVOID: Excessive use or abrupt discontinuation of alcohol after chronic ingestion may precipitate seizures in patients receiving bupropion. Additionally, there have been rare postmarketing reports of adverse neuropsychiatric events or reduced alcohol tolerance in patients who drank alcohol during treatment with bupropion. According to one forensic report, a patient died after taking large doses of both bupropion and alcohol. It is uncertain whether a drug interaction was involved. Single-dose studies in healthy volunteers given bupropion and alcohol failed to demonstrate either a significant pharmacokinetic or pharmacodynamic interaction.

MANAGEMENT: The manufacturer recommends that alcohol consumption be minimized or avoided during bupropion treatment. The use of bupropion is contraindicated in patients undergoing abrupt discontinuation of alcohol.

aspirin food

Applies to: aspirin / caffeine / salicylamide

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

buPROPion food

Applies to: Wellbutrin XL (bupropion)

MONITOR: The concomitant use of bupropion and nicotine replacement for smoking cessation may increase the risk of hypertension. In a clinical study (n=250), 6.1% of patients who used sustained-release bupropion with nicotine transdermal system developed treatment-emergent hypertension, compared to 2.5% of patients treated with bupropion alone, 1.6% treated with nicotine alone, and 3.1% treated with placebo. Three patients in the bupropion plus nicotine group and one patient in the nicotine-only group discontinued treatment due to hypertension. The majority had evidence of preexisting hypertension.

MANAGEMENT: Blood pressure monitoring is recommended for patients concomitantly using bupropion and nicotine replacement for smoking cessation.

caffeine food

Applies to: aspirin / caffeine / salicylamide

The effect of grapefruit juice on the pharmacologic activity of caffeine is controversial. One report suggests that grapefruit juice increases the effect of caffeine. The proposed mechanism is inhibition of cytochrome P-450 metabolism of caffeine. However, a well-conducted pharmacokinetic/pharmacodynamic study did not demonstrate this effect. The clinical significance of this potential interaction is unknown.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
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.
Unknown No interaction information available.
