Sudafed (pseudoephedrine HCI) is a decongestant prescribed for the temporary relief of nasal congestion due to the common cold, hay fever, and sinus congestion. Sudafed is available as a generic drug. Common side effects of Sudafed include:

  • nervousness,
  • restlessness or excitability (especially in children),
  • dizziness,
  • headache,
  • fear,
  • anxiety,
  • loss of appetite,
  • sleep problems (insomnia),
  • skin rash,
  • itching,
  • tremors,
  • hallucinations,
  • convulsions (seizures),
  • nausea,
  • vomiting, and
  • flushing (warmth, tingling, or redness under your skin).

Sudafed usual dose is one tablet every 12 hours. Sudafed drug interactions include monoamine oxidase inhibitors or MAOIs (for example, isocarboxazid [Marplan]), serotonin and norepinephrine reuptake inhibitors (for example, venlafaxine [Effexor]), bronchodilators (for example, albuterol [Proventil]), blood pressure medications (such as beta blockers [Atenolol]) and calcium channel blockers [for example, verapamil]). Tell your doctor if you are pregnant or plan to become pregnant while using Sudafed; it is unknown if Sudafed will harm a fetus. Sudafed passes into breast milk and may harm a nursing baby.
