Description
Reactine 5mg (Cetirizine)
Reactine 5mg is a lower-strength antihistamine tablet used to relieve seasonal and year-round allergy symptoms — sneezing, runny nose, nasal congestion, and itchy, watery eyes — as well as allergic skin conditions like hives and itching. Its active ingredient, cetirizine, works by blocking histamine, the chemical the body releases during an allergic reaction.
The 5mg strength is often used for milder allergy symptoms, for people who are more sensitive to antihistamines, or as directed by a doctor for children or older adults who may need a lower dose than the standard 10mg tablet. Like other Reactine strengths, it typically starts working within about 20 minutes and provides relief for up to 24 hours.
Who It's For
Reactine 5mg is commonly used by:
- People with mild seasonal or year-round allergy symptoms
- Children (2 years and older, under a doctor's guidance) who need a lower dose than the standard adult strength
- Adults who are more sensitive to antihistamine side effects like drowsiness
- Anyone whose doctor has specifically recommended the lower-strength dose
How to Use
Swallow the tablet whole with water — don't crush or chew it. Dosage should follow your doctor's or pharmacist's instructions, since the right amount can depend on age and the symptoms being treated. If allergy symptoms or hives haven't improved after 3 days, check in with a doctor. In children, Reactine shouldn't be used for more than 14 days at a time unless a doctor specifically recommends longer use.
Side Effects
Common side effects include dry mouth, headache, loss of taste, or drowsiness. Because Reactine can cause drowsiness, avoid driving or operating machinery until you know how it affects you. Seek medical attention right away for blurred vision, hallucinations, a new rash, painful urination, or signs of a serious allergic reaction.
Precautions
Don't take Reactine 5mg if you're allergic to cetirizine or any of its ingredients. Tell your doctor about any history of kidney problems, liver disease, or difficulty urinating, and if you're pregnant or breastfeeding. Cetirizine can interact with certain medications, including donepezil, atropine, clidinium, efavirenz, ketamine, valerian, and trazodone — share your full medication and supplement list with your doctor. Store at room temperature, away from light and moisture, out of reach of children.
