Medications for Asthma Attacks That Can Cause Penile and Testicular Burning

Epinephrine (adrenaline) is the medication used for severe asthma attacks that can cause penile and testicular burning sensations. 1

Medications Used in Acute Asthma Attacks

During acute asthma attacks, several medications are commonly administered:

  • Beta-agonists (salbutamol/albuterol or terbutaline) are first-line treatments delivered via nebulizer or metered-dose inhaler 1
  • Systemic corticosteroids (prednisolone or hydrocortisone) are added for moderate to severe attacks 1
  • Ipratropium bromide may be added in severe cases 1
  • Aminophylline or intravenous beta-agonists may be used in life-threatening cases 1
  • Epinephrine (adrenaline) is reserved for catastrophic, sudden severe asthma when other treatments have failed 1

Epinephrine and Genital Side Effects

In cases of catastrophic, sudden severe asthma (also called brittle asthma), epinephrine is recommended when other treatments have failed:

  • Epinephrine (0.5 mg) via subcutaneous injection is recommended for patients with catastrophic asthma when nebulized beta-agonists have failed 1
  • Epinephrine acts as a non-selective adrenergic agonist, stimulating both alpha and beta receptors 1
  • The alpha-adrenergic effects cause vasoconstriction and can affect blood vessels in genital tissues 1
  • This vasoconstriction can lead to sensations of burning or discomfort in penile and testicular areas 1

Clinical Considerations

When administering epinephrine for severe asthma attacks:

  • Patients should be informed about possible side effects, including genital discomfort 1
  • The benefit of preventing mortality in catastrophic asthma outweighs the temporary discomfort of these side effects 1
  • Symptoms typically resolve as the medication is metabolized and eliminated from the body 1
  • Alternative medications should be considered if a patient has previously experienced severe genital discomfort with epinephrine 1

Management of Catastrophic Asthma

For patients with catastrophic sudden severe asthma, the British Thoracic Society recommends the following management plan:

  1. Call for help immediately 1
  2. Administer high-dose inhaled beta-agonists (salbutamol 5 mg or terbutaline 10 mg) or multiple puffs from a metered-dose inhaler 1
  3. If previous management has failed, use subcutaneous epinephrine (0.5 mg) 1
  4. Administer oral prednisolone 30-60 mg 1
  5. Transport to the nearest hospital immediately 1

Pitfalls and Caveats

  • Genital burning sensations may be mistakenly attributed to other causes when they are actually a side effect of epinephrine 1
  • These symptoms are transient and should resolve as the medication is metabolized 1
  • The life-saving benefits of epinephrine in catastrophic asthma outweigh the temporary discomfort 1
  • Patients with a history of this side effect should inform healthcare providers, but this should not prevent the use of epinephrine in life-threatening situations 1
