What are the treatment options for premature ejaculation in a male patient of reproductive age with potential underlying conditions such as diabetes, hypertension, or depression?

Treatment of Premature Ejaculation

Daily SSRI therapy is the most effective first-line treatment for premature ejaculation, with paroxetine 10-40 mg daily providing the strongest ejaculatory delay (8.8-fold increase over baseline), followed by sertraline 50-200 mg daily as an alternative. 1, 2

First-Line Pharmacological Treatment Algorithm

Daily SSRI Therapy (Preferred)

• Paroxetine 10-40 mg daily is the most potent option, producing an 8.8-fold increase in ejaculatory latency time (IELT) 1, 2
• Sertraline 50-200 mg daily is an effective alternative with similar efficacy 1, 2
• Fluoxetine 20-40 mg daily and citalopram 20-40 mg daily are additional options 1
• Daily dosing provides more consistent and stronger ejaculatory delay compared to on-demand use 2

On-Demand SSRI Therapy (Alternative)

• Paroxetine 20 mg taken 3-4 hours before intercourse provides moderate efficacy but substantially less delay than daily treatment 1, 2
• Clomipramine 12.5-50 mg taken 3-6 hours before intercourse is modestly efficacious 1
• Dapoxetine 30-60 mg taken 1-3 hours before intercourse (where available) produces a 2.5-3.0-fold increase in IELT, with the 60 mg dose showing 3.0-fold increase 2
• On-demand therapy is appropriate for men with infrequent sexual activity or concerns about daily medication 2

Topical Anesthetics

• Lidocaine/prilocaine cream or spray (EMA-approved formulation: lidocaine 150 mg/ml + prilocaine 50 mg/ml) increases IELT up to 6.3-fold over 3 months 1, 2
• Minimal systemic effects with only minor local side effects (genital hypoesthesia) 2
• Recommended for patients concerned about systemic medication effects 2

Treatment Selection Based on Clinical Context

For Men with Frequent Sexual Activity

• Start with paroxetine 10-20 mg daily, titrating to 40 mg if needed 1, 2
• If paroxetine is not tolerated, switch to sertraline 50 mg daily, titrating to 200 mg 1, 2

For Men with Infrequent Sexual Activity

• Use on-demand paroxetine 20 mg taken 3-4 hours before intercourse 2
• Alternative: dapoxetine 30-60 mg taken 1-3 hours before intercourse (where available) 2

For Men with Severe PE (IELT <30-60 seconds)

• Combination therapy with daily low-dose SSRI plus on-demand dosing may be considered 2
• Topical anesthetic plus oral SSRI can considerably increase IELT compared to monotherapy 3

For Men with Coexisting Erectile Dysfunction

• Treat erectile dysfunction first or concomitantly, as some acquired PE may be secondary to ED 2
• Combination of SSRI plus PDE5 inhibitor shows superior results to SSRI monotherapy and enhances confidence and sexual satisfaction 2
• PDE5 inhibitors should not be prescribed alone to men with PE and normal erectile function 2

Important Side Effects and Safety Considerations

Common Sexual Side Effects

• Ejaculatory dysfunction occurs in 11-23% of men on SSRIs (compared to 1% on placebo) 4, 5
• Decreased libido occurs in 6-9% of men on sertraline and 3% on paroxetine 4, 5
• These side effects are paradoxically therapeutic in PE but should be monitored 4

Other Common Adverse Events

• Nausea (25-28% with sertraline, similar with paroxetine) 4, 5
• Insomnia (21-25% with sertraline) 4
• Dry mouth (14-16% with sertraline, 9-12% with paroxetine) 4, 5
• Sweating increased (7-11%) 4, 5
• Treatment cessation due to adverse events increases 3.8-fold with SSRIs compared to placebo 6

Critical Safety Warnings

• Never abruptly discontinue daily SSRI therapy as this may precipitate SSRI withdrawal syndrome; taper gradually 7
• Avoid SSRIs in patients with bipolar disorder history due to risk of precipitating mania 7
• Exercise caution in adolescents and patients with comorbid depression, particularly those with suicidal ideation 7
• Serotonin syndrome is a potentially serious complication most often associated with simultaneous use of multiple serotonergic drugs (e.g., SSRI, TCA, recreational drugs such as amphetamine or cocaine) 1

Psychological and Behavioral Considerations

When to Add Psychotherapy

• Psychological factors including depression, anxiety, history of sexual abuse, decreased emotional intimacy, and relationship conflict are associated with PE 1
• Psychotherapy may be useful even when no clear psychological etiology is apparent 1, 2
• Men with PE have significantly lower self-esteem, self-confidence, more interpersonal conflict, and more anxiety compared to men without PE 1

Evaluation Requirements

• Physical examination rarely contributes to PE evaluation but should be conducted when possible to reassure patients and identify other issues 1
• Additional laboratory testing is not routinely necessary for lifelong PE 1
• For acquired PE, additional testing may be utilized as clinically indicated to evaluate for conditions like diabetes, hyperthyroidism, or elevated glucose/HbA1c 1

Common Pitfalls to Avoid

• Do not use on-demand dosing as initial therapy for men with frequent sexual activity, as daily dosing provides substantially better results 1, 2
• Do not prescribe PDE5 inhibitors alone for PE without erectile dysfunction, as they do not significantly improve IELT 2
• Do not ignore coexisting erectile dysfunction, as treating ED may resolve secondary PE 2
• Do not add additional serotonergic agents if a patient is already on an SSRI for depression, as this increases serotonin syndrome risk 1
• Dapoxetine has 90% discontinuation rates at 2 years, mainly due to cost and disappointment with on-demand nature 2
