What is the best management approach for a 30-year-old male with a history of alcoholism, hypertension, orthostatic hypotension, erectile dysfunction, and sleep disturbances, who is currently being treated with bupropion (Wellbutrin) and naltrexone (Revia)?

Management of a 30-Year-Old Male with Alcoholism, Hypertension, Orthostatic Hypotension, Erectile Dysfunction, and Sleep Disturbances on Bupropion and Naltrexone

Critical Safety Assessment Required Immediately

You must discontinue naltrexone immediately and reassess this patient's medication regimen due to multiple concerning contraindications and adverse effects that are likely causing or worsening his symptoms. 1, 2

Why Naltrexone Must Be Stopped

• Naltrexone is directly causing or significantly worsening his orthostatic hypotension (pulse rate difference between sitting and lying down), as cardiovascular drugs including opioid antagonists are well-documented causes of drug-induced orthostatic hypotension 3
• Uncontrolled hypertension is an absolute contraindication for the bupropion-naltrexone combination, and this patient has hypertension that may not be adequately controlled given his orthostatic symptoms 4, 1, 2
• The combination of naltrexone-bupropion ER requires regular blood pressure and heart rate monitoring, especially during the first 12 weeks, which appears not to have been adequately performed 4, 1

Why Bupropion Alone May Also Be Problematic

• Bupropion can elevate blood pressure and heart rate, making it contraindicated in uncontrolled hypertension 4, 1, 2
• His orthostatic hypotension suggests autonomic dysfunction, possibly alcohol-related, which makes him particularly vulnerable to medications affecting cardiovascular parameters 3
• Sleep disturbances are a common side effect of bupropion, and the second dose must be given before 3 PM to minimize insomnia risk 1

Immediate Management Steps

Step 1: Discontinue Current Medications Safely

• Stop naltrexone immediately - no taper is required for naltrexone as it is not associated with withdrawal symptoms 5
• Taper bupropion gradually over 1-2 weeks to minimize potential withdrawal symptoms, reducing from current dose to 150 mg daily, then 75 mg daily, then discontinue 1
• Monitor blood pressure in both supine and standing positions daily during this transition 3

Step 2: Address Alcohol Dependence with Appropriate Pharmacotherapy

Switch to acamprosate as first-line therapy for maintaining abstinence, as it is specifically indicated for patients who have achieved abstinence and wish to maintain it, and does not cause orthostatic hypotension 4, 6, 7

• Acamprosate dosing: 666 mg (two 333 mg tablets) three times daily, starting after the patient achieves abstinence 4
• Acamprosate reduces withdrawal symptoms and alcohol craving, decreases relapse rates, and maintains abstinence when combined with counseling 4, 6
• Critical advantage: Acamprosate has no cardiovascular effects and will not worsen his hypertension or orthostatic hypotension 7
• Acamprosate is more effective in maintaining rather than inducing remission, making it ideal for this patient who is "doing okay" on current therapy 4

Step 3: Manage Hypertension and Orthostatic Hypotension

• Avoid alpha-1 blockers, centrally acting antihypertensives, and high-dose diuretics, as these are the most common causes of drug-induced orthostatic hypotension 3
• Consider ACE inhibitors or calcium channel blockers as first-line agents for hypertension, as these have lower risk of orthostatic hypotension 3
• Ensure adequate hydration and sodium intake to help manage orthostatic symptoms 3
• Measure orthostatic vital signs: blood pressure and pulse after 5 minutes supine, then immediately upon standing and at 3 minutes standing 3

Step 4: Address Erectile Dysfunction

• The erectile dysfunction is likely multifactorial: alcohol-related autonomic neuropathy, medication side effects, and vascular disease from hypertension 3
• Once cardiovascular status is stabilized and alcohol abstinence maintained, consider phosphodiesterase-5 inhibitors (sildenafil, tadalafil) if no contraindications exist 3
• Do not use bupropion as a strategy to avoid sexual dysfunction, as this patient has contraindications to its use 1, 2

Step 5: Manage Sleep Disturbances

• Sleep disturbances in alcoholics are common and may improve with sustained abstinence 4
• Avoid sedative-hypnotics initially, as they carry risk of dependence in this population 4
• Consider low-dose trazodone (50-100 mg at bedtime) or mirtazapine (15-30 mg at bedtime) if sleep disturbances persist after 2-4 weeks of abstinence 8
• Cognitive behavioral therapy for insomnia (CBT-I) should be the first-line non-pharmacological intervention 8

Ongoing Monitoring and Support

Essential Monitoring Parameters

• Orthostatic vital signs weekly for the first month, then monthly 3
• Liver function tests at baseline and every 3 months, as this patient likely has alcoholic liver disease given his history 4
• Abstinence monitoring through patient self-report, collateral information from family, and consideration of random alcohol biomarkers 4, 9
• Screen for depression and suicidal ideation at each visit, as these are common in alcohol dependence 9, 8

Psychosocial Interventions Are Mandatory

• Acamprosate must be combined with counseling and support to be effective 4, 6
• Refer to Alcoholics Anonymous or other mutual support groups 4
• Consider intensive outpatient program if available 4
• Recidivism rates are 67-81% over one year, so ongoing monitoring and support are critical 4

Common Pitfalls to Avoid

• Never use naltrexone in patients with orthostatic hypotension or uncontrolled hypertension - this is a critical safety issue that was missed in this patient 4, 2, 3
• Do not assume bupropion is safe for all patients with alcohol dependence - screen carefully for cardiovascular contraindications 1, 2
• Do not prescribe disulfiram - it has poor tolerability, minimal evidence of efficacy, and can cause hepatotoxicity in patients who may already have alcoholic liver disease 4, 6
• Do not use SSRIs as primary treatment for alcohol dependence unless there is comorbid depression, as evidence for their efficacy in primary alcohol dependence is limited 6, 8

Alternative if Acamprosate Fails or Is Not Tolerated

If acamprosate is ineffective after 3-6 months or not tolerated, consider topiramate 300 mg daily (titrated gradually from 25 mg daily), which has evidence of efficacy but is off-label for alcohol dependence 9, 7
