Montelukast May Interact with Other Medications
An interaction is when a substance changes the way a drug works. This can be harmful or prevent the drug from working well. To help prevent interactions, your doctor should manage all of your medications carefully. Be sure to tell your doctor about all medications, vitamins, or herbs you’re taking.
To find out how montelukast might interact with something else you’re taking, talk to your doctor or pharmacist.
Disclaimer: Our goal is to provide you with the most relevant and current information. However, because drugs interact differently in each person, we cannot guarantee that this information includes all possible interactions. This information is not a substitute for medical advice. Always speak with your healthcare provider about possible interactions with all prescription drugs, vitamins, herbs and supplements, and over-the-counter drugs that you are taking. Drug warningsPeople with aspirin or NSAID allergy
If you have a sensitivity or allergy to aspirin or non-steroidal anti-inflammatory drugs (NSAIDs), you should continue to avoid these drugs while taking this drug. Sensitivity to these drugs may lead to tightening of your airways, and this drug may not fully treat these symptoms.
Pregnant women
This drug is a category B pregnancy drug. That means two things:
- Studies of the drug in pregnant animals have not shown a risk to the fetus.
- There aren’t enough studies done in pregnant women to show if the drug poses a risk to the fetus.
Talk to your doctor if you’re pregnant or planning to become pregnant. This drug should be used only if the potential benefit justifies the potential risk to the fetus.
Women who are breast-feeding
It is not known if this drug passes into breast milk or causes side effects in a child who is breast-fed.
Talk to your doctor if you breast-feed your child. You may need to decide whether to stop breast-feeding or stop taking this medication.
For seniors
The kidneys of older adults may not work as well as they used to. This can cause your body to process drugs more slowly. As a result, more of a drug stays in your body for a longer time. This raises your risk of side effects.
When to call the doctor
Go to the emergency room if you have an asthma attack that is not relieved by using a rescue inhaler. Early signs of an asthma attack include cough, wheezing, losing your breath easily, or feeling short of breath. They also include feeling tired, having trouble sleeping, or having allergy symptoms (such as sneezing, runny nose, nasal congestion, or headache).
Call your doctor if you become pregnant while taking this drug.
Allergies
This drug can cause a severe allergic reaction. Symptoms can include:
- swelling of the face, lips, tongue, and/or throat
- trouble breathing
- hives
- itching
If you have a reaction, call your doctor or local poison control center right away. If your symptoms are severe, call 9-1-1 or go to the nearest emergency room.
Don’t take this drug again if you’ve ever had an allergic reaction to it. Taking it again could be fatal (cause death).
