Fexofenadine 120 mg – What You Need to Know
If you suffer from hay fever, hives, or other allergy symptoms, you’ve probably heard of fexofenadine. It’s a non‑sedating antihistamine that blocks the body’s histamine response, keeping sneezing, itching, and watery eyes at bay. The 120 mg tablet is one of the most common strengths sold in the UK and many other countries. Below you’ll find plain‑English advice on how to use it, what to watch out for, and when to call a pharmacist or doctor.
What Is Fexofenadine 120 mg?
Fexofenadine belongs to the second‑generation antihistamine group. Unlike older antihistamines, it usually doesn’t make you feel drowsy, so you can take it before work or school without crashing. The 120 mg tablet is designed for adults and children over 12 years old. It works by stopping histamine – a chemical your body releases during an allergic reaction – from binding to its receptors. The result is less swelling, less itch, and clearer breathing.
How to Take It Safely
Most people take one 120 mg tablet once a day. You can swallow it whole with a glass of water. Taking it with food doesn’t change its effect, but a high‑fat meal can slightly slow absorption, meaning you might feel relief a little later. If you miss a dose, just take it as soon as you remember – unless it’s almost time for the next one. In that case, skip the missed tablet and keep to your regular schedule; don’t double up.
Here are a few practical pointers:
- Store the tablets in a cool, dry place away from children.
- Don’t crush or chew them – the coating helps the medicine work properly.
- Check the expiry date; old tablets lose potency.
Most side effects are mild. Some people notice a headache, dry mouth, or a little stomach upset. If you get a rash, swelling of the face, or trouble breathing, stop the medicine and seek medical help right away – those could be signs of a rare allergic reaction.
Fexofenadine can interact with a few other drugs. Antacids that contain aluminum or magnesium, as well as certain antibiotics like clarithromycin, may lower the amount of fexofenadine your body absorbs. If you’re on any of these, talk to your pharmacist about timing – usually spacing the doses by a couple of hours helps.
Pregnant or breastfeeding moms should only use fexofenadine if a doctor says it’s necessary. The drug is generally considered low‑risk, but it’s best to get professional advice first.
When you start a new batch, keep an eye on how you feel. If symptoms don’t improve after a few days, or if they get worse, it could be that you need a different antihistamine or an additional treatment like a nasal spray.
Bottom line: fexofenadine 120 mg is a reliable, non‑sedating option for most allergy sufferers. Take it as directed, watch for interactions, and you’ll likely enjoy clearer days during pollen season or anytime allergies flare up.
