Numark Max Strength Congestion Relief (Phenylephrine Hydrochloride)

Numark Max Strength Congestion Relief contains phenylephrine, a sympathomimetic agent that reduces nasal swelling in the upper respiratory tract.

• Common cold: alleviates nasal congestion and improves airflow.
• Allergic rhinitis: reduces nasal blockage caused by histamine‑mediated swelling.
• Sinusitis: helps clear sinus passages by decreasing mucosal edema.
• Upper respiratory infections: eases congestion symptoms during viral infections.

• Phenylephrine acts as an alpha‑adrenergic agonist, primarily stimulating α1‑adrenergic receptors on the smooth muscle of nasal blood vessels. This causes vasoconstriction, which reduces blood flow to the nasal mucosa, decreasing swelling and opening the airway for easier breathing.

Phenylephrine may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Headache: mild to moderate intensity.
• Dizziness: transient light‑headedness.
• Nausea: occasional upset stomach.
• Tremor: fine muscle tremors, especially at higher doses.
• Insomnia: difficulty falling or staying asleep.
• Elevated blood pressure: mild, temporary rise in systolic pressure.

Serious or Rare Side Effects

• Severe hypertension: marked increase in blood pressure requiring medical attention.
• Cardiac arrhythmia: irregular heart rhythm, potentially life‑threatening.
• Cerebral hemorrhage: rare intracranial bleeding event.
• Allergic reaction: rash, itching, swelling, or anaphylaxis.
• Pulmonary edema: fluid accumulation in the lungs.
• Ischemic stroke: rare cerebrovascular accident.
