Montelukast 10 mg: What You Need to Know

If you’ve been prescribed a white tablet marked "10 mg," you’re probably looking at Montelukast. It’s a leukotriene receptor antagonist that helps keep asthma attacks and allergy flare‑ups in check. Let’s break down how to use it, what to expect, and when to call your doctor.

How to Take Montelukast 10 mg

Take the tablet once daily, preferably at the same time each day. Most doctors recommend bedtime because asthma symptoms often worsen at night. You can swallow it whole with water – no need to chew or crush.

If you miss a dose, take it as soon as you remember unless it’s almost time for your next scheduled dose. In that case, skip the missed one and continue with your regular schedule. Don’t double up.

Who Should Use Montelukast?

The drug works for adults and kids over 12 who have:

• Persistent asthma
• Exercise‑induced bronchoconstriction
• Seasonal allergic rhinitis (hay fever)

It’s also approved for chronic obstructive pulmonary disease (COPD) in some countries, but your doctor will decide based on your health profile.

Common Side Effects You Might Feel

Most people tolerate Montelukast well. The most reported issues are mild and go away on their own:

• Headache
• Dizziness
• Nausea or stomach upset

If you notice a rash, swelling, or sudden mood changes (like anxiety or depression), stop the medication and seek medical help right away. These are rare but can signal an allergic reaction.

Safety Tips & Interactions

Tell your doctor about any other meds you’re taking – especially antidepressants, antiepileptics, or blood thinners – because they can interact with Montelukast. Alcohol isn’t a direct problem, but it can worsen dizziness.

Pregnant or breastfeeding? Discuss the risks; most guidelines say it’s okay, but only your doctor can give the final word.

When to Call Your Doctor

If you experience any of these, pick up the phone:

• Worsening asthma symptoms despite daily use
• Severe headache that won’t go away
• Signs of an allergic reaction (hives, swelling, trouble breathing)

Also, if you’re planning surgery or a major dental procedure, let your healthcare team know you’re on Montelukast – they may need to adjust doses.

Bottom Line

Montelukast 10 mg is a convenient once‑daily pill that can keep asthma and allergy symptoms under control for many people. Stick to the same time each day, watch for side effects, and keep your doctor in the loop. With those basics covered, you’ll get the most benefit out of this medication without unnecessary hassle.
