Sinutab Extra Strength is a popular over-the-counter medication designed to combat the combined symptoms of sinus congestion, allergies, and the common cold. Rather than addressing just one symptom, it provides a comprehensive solution by including three distinct active ingredients, each targeting a specific type of discomfort. This multi-action approach is what makes it an effective choice for many who suffer from sinus pain, pressure, headaches, and other related issues.
The Active Ingredients
Each caplet of Sinutab Extra Strength contains three active medicinal ingredients that work together to provide relief. These ingredients have different mechanisms of action to address the various symptoms associated with sinus issues and allergies.
- Acetaminophen: This is a widely used analgesic and antipyretic, meaning it works to relieve pain and reduce fever. In the context of sinus relief, acetaminophen helps to alleviate the pain and pressure often felt in the head and face, and can also help with an accompanying fever. It works by inhibiting the production of prostaglandins in the brain, which are involved in the body's pain and fever responses.
- Pseudoephedrine Hydrochloride: As a nasal decongestant, pseudoephedrine hydrochloride is a sympathomimetic amine that helps to shrink swollen blood vessels in the nasal passages. This action reduces inflammation and congestion, allowing for easier breathing. Unlike oral decongestants containing phenylephrine, pseudoephedrine is generally considered more effective at relieving congestion, though it is often kept behind the pharmacy counter due to regulations.
- Chlorpheniramine Maleate: This is an antihistamine that helps to alleviate allergy-like symptoms. It works by blocking histamine, a chemical the body releases during an allergic reaction, which causes symptoms such as sneezing, runny nose, and itchy, watery eyes. Because chlorpheniramine is a first-generation antihistamine, it can also cause drowsiness.
Non-Medicinal Ingredients
In addition to the active medicinal ingredients, Sinutab Extra Strength caplets also contain non-medicinal components that aid in the formulation of the tablet. These can include cellulose, croscarmellose sodium, hypromellose, polyethylene glycol, polysorbate, starch, titanium dioxide, wax, and zinc stearate. These substances help to bind the caplet together and ensure its stability.

Important Safety Information and Precautions
Despite being an over-the-counter medication, Sinutab Extra Strength should be used with caution and as directed. The combination of active ingredients can cause certain side effects and may interact with other medications.
- Risk of Liver Damage: The acetaminophen in Sinutab can cause severe liver damage, especially if more than the recommended amount is taken or if consumed with alcohol. Always check labels to avoid taking other products containing acetaminophen at the same time.
- Contraindications: People with certain medical conditions should consult a doctor before using this medication. These include individuals with high blood pressure, heart problems, liver or kidney disease, diabetes, glaucoma, or an overactive thyroid.
- Interactions: Sinutab Extra Strength can interact with various medications, including MAO inhibitors, blood thinners, and other cough and cold medicines. It's crucial to consult a pharmacist or doctor about potential interactions before taking it with any other drug.
- Side Effects: Common side effects include dizziness, drowsiness, dry mouth, nervousness, and trouble sleeping. In older adults, effects like confusion and urinary problems may be more likely. The antihistamine component, chlorpheniramine, is the primary cause of the drowsiness effect.
