Fexofenadine 180 mg: What You Need to Know

If you suffer from seasonal allergies, you’ve probably heard of fexofenadine. The 180 mg tablet is the most common strength sold over the counter in many countries. It blocks histamine, the chemical that makes you itchy, sniffly, and watery‑eyed. Below we break down how to use it, what to expect, and where to get it without hassle.

How to Take Fexofenadine 180 mg

Take one tablet once a day, preferably with water. You can swallow it with or without food, but a big meal or dairy can slow absorption, so many recommend taking it on an empty stomach for fastest relief. The effect usually starts within an hour and can last up to 24 hours. If you miss a dose, skip it and resume your regular schedule – don’t double up.

Adults and children over 12 years old can use the 180 mg strength. Kids younger than 12 need a lower dose, usually 30 mg or 60 mg, based on weight. Always follow the label or your doctor’s instructions.

Common Side Effects and Safety Tips

Most people tolerate fexofenadine well. The most reported side effects are mild headache, dry mouth, and occasional drowsiness, though the drug is labeled “non‑sedating.” If you notice a rash, swelling, or trouble breathing, stop the medication and seek medical help right away – those could be signs of a rare allergic reaction.

Fexofenadine can interact with certain medicines, especially those that affect the liver enzyme CYP3A4, like some antibiotics and antifungals. Alcohol doesn’t usually cause problems, but heavy drinking can raise the chance of dizziness. If you have kidney problems, talk to a pharmacist; dose adjustments might be needed.

When buying fexofenadine 180 mg, stick to reputable pharmacies – online or brick‑and‑bone. Look for a clear expiration date, proper packaging, and a trusted brand name. In the UK, you’ll find it listed under the name Allegra; in the US, Allegra is also common, but generic versions are available at a lower price.

Don’t buy from sites that have no contact information or that promise “miracle cures.” If a price looks too good to be true, it probably is. Checking reviews and confirming the seller’s registration with your national pharmacy board helps avoid counterfeit pills.

For most people, fexofenadine 180 mg is a safe, effective way to keep allergy symptoms at bay during pollen season or when dealing with pet dander. Remember to keep the tablets out of reach of children, store them in a cool dry place, and replace any that are past the expiry date.

Got more questions? Common queries include: "Can I take fexofenadine with my blood pressure meds?" – generally yes, but check with your doctor. "How long can I use it?" – daily use is fine, but if you need it for months on end, a check‑up is wise. And "What’s the difference between 180 mg and 60 mg?" – the higher dose simply provides a stronger, longer‑lasting block of histamine.

Bottom line: fexofenadine 180 mg works fast, lasts long, and fits easily into a busy schedule. Follow the dosage rules, watch for side effects, and buy from a trusted source, and you’ll stay comfortable through allergy season.
