About Fexofenadine + Pseudoephedrine
Indications of Fexofenadine + Pseudoephedrine
Fexofenadine + Pseudoephedrine is a fixed-dose combination of a non-sedating (second-generation) antihistamine, fexofenadine, and a sympathomimetic nasal decongestant, pseudoephedrine. It is indicated for the relief of symptoms associated with seasonal allergic rhinitis (hay fever) in adults and adolescents.
Established / FDA-approved uses
- Seasonal allergic rhinitis with nasal congestion: relief of nasal congestion together with sneezing, rhinorrhea (runny nose), itchy/watery eyes, and itching of the nose or throat caused by seasonal allergies (e.g., pollen).
Important limitations
Fexofenadine + Pseudoephedrine is intended only for patients who have both allergic symptoms (histamine-mediated) AND nasal congestion. It is not indicated for the common cold, for allergic rhinitis without congestion (fexofenadine alone is preferred in that case), or for chronic idiopathic urticaria (fexofenadine alone is used for that indication). Fexofenadine + Pseudoephedrine is not an antibiotic and does not treat sinus infections or bacterial illness.
Dosage & Administration of Fexofenadine + Pseudoephedrine
General dosing principles
Fexofenadine + Pseudoephedrine is taken orally, generally with water, and should not be split or chewed if it is an extended-release tablet. Dosing depends on the specific product strength (12-hour vs 24-hour formulation); always follow the specific brand's labeled dose.
| Population | Typical dose | Notes |
|---|---|---|
| Adults and adolescents ≥12 years (60 mg/120 mg 12-hour product) | One tablet twice daily, morning and evening, with a full glass of water, not exceeding two tablets in 24 hours | Swallow whole; do not crush or chew |
| Adults and adolescents ≥12 years (180 mg/240 mg 24-hour product, where available) | One tablet once daily with water | Swallow whole; do not crush or chew |
| Renal impairment | Reduced clearance of both components is expected; use with caution and under physician guidance, with dose/frequency adjustment or use of individual components as directed | See Use in Special Populations |
Pediatric dosing
Fexofenadine + Pseudoephedrine extended-release combination tablets are generally not recommended for children under 12 years of age, as safety and efficacy have not been established in this age group for the fixed-dose combination (see Pediatric Uses).
Duration
Use for the shortest period needed to control seasonal allergy symptoms; do not use for more than 7 days without consulting a physician, as prolonged decongestant use can be associated with rebound congestion and increased cardiovascular stimulant effects (see Duration of Treatment).
Side Effects of Fexofenadine + Pseudoephedrine
Side effects reported with Fexofenadine + Pseudoephedrine reflect the combined effects of both components:
Common
- Insomnia, nervousness, restlessness, or anxiety (pseudoephedrine)
- Headache
- Dizziness
- Dry mouth or throat irritation
- Nausea
- Palpitations or a sensation of rapid heartbeat
Less common but clinically important
- Significant elevation of blood pressure or heart rate, especially in predisposed patients
- Tremor
- Difficulty urinating/urinary retention, particularly in men with prostatic enlargement
- Hypersensitivity reactions, including rash, urticaria, and rarely angioedema
- Rare cardiac arrhythmias or seizures with excessive intake
Seek prompt medical advice for signs of an allergic reaction, chest pain, marked palpitations, severe dizziness, or difficulty breathing (see Precautions and Warnings).
Contraindications of Fexofenadine + Pseudoephedrine
Fexofenadine + Pseudoephedrine is contraindicated in the following situations:
- Known hypersensitivity to fexofenadine, pseudoephedrine, or any component of the formulation.
- Concurrent use of, or use within 14 days of discontinuing, monoamine oxidase inhibitor (MAOI) therapy, due to the risk of hypertensive crisis with pseudoephedrine.
- Narrow-angle (angle-closure) glaucoma, because the sympathomimetic (mydriatic) effect of pseudoephedrine can precipitate an acute attack.
- Severe hypertension or severe coronary artery disease, in which pseudoephedrine's sympathomimetic cardiovascular stimulant effects pose an unacceptable risk.
Frequently Asked Questions about Fexofenadine + Pseudoephedrine
What is Fexofenadine + Pseudoephedrine used for?
Fexofenadine + Pseudoephedrine is used to relieve the symptoms of seasonal allergic rhinitis (hay fever) that include both allergy symptoms — sneezing, runny nose, itchy/watery eyes — and nasal congestion. Fexofenadine treats the allergic symptoms and pseudoephedrine relieves the stuffy nose.
Can I take Fexofenadine + Pseudoephedrine if I have high blood pressure?
Use caution. Fexofenadine + Pseudoephedrine is contraindicated in severe hypertension because the pseudoephedrine component can raise blood pressure and heart rate. If you have mild to moderate hypertension, discuss with your physician before using Fexofenadine + Pseudoephedrine, and monitor your blood pressure during use.
How long can I take Fexofenadine + Pseudoephedrine?
Fexofenadine + Pseudoephedrine is generally intended for short-term use, typically no more than 7 days, without consulting a physician. Prolonged use of the decongestant component can lead to rebound congestion when stopped and sustained stimulant effects on the heart and nervous system. See a doctor if symptoms last longer than a week or worsen.
Is Fexofenadine + Pseudoephedrine safe during pregnancy or breastfeeding?
Data are limited. Fexofenadine + Pseudoephedrine should be used during pregnancy only if clearly needed and the potential benefit outweighs the potential risk to the fetus, particularly avoiding use in the first trimester unless advised by a physician. During breastfeeding, use with caution and consult your physician first, since pseudoephedrine may also reduce milk supply.
Can I take Fexofenadine + Pseudoephedrine with fruit juice?
It is best to take Fexofenadine + Pseudoephedrine with plain water rather than fruit juices such as apple, orange, or grapefruit juice, because these juices can reduce the absorption of the fexofenadine component and make it less effective.
Who should not take Fexofenadine + Pseudoephedrine?
Fexofenadine + Pseudoephedrine should not be taken by anyone with a known hypersensitivity to fexofenadine, pseudoephedrine, or any ingredient in the tablet; anyone currently taking, or who stopped within the last 14 days, a monoamine oxidase inhibitor (MAOI); anyone with narrow-angle glaucoma; or anyone with severe hypertension or severe coronary artery disease. Always inform your physician of your full medical history before starting Fexofenadine + Pseudoephedrine.
