Pharmacist tips for Zafirlukast (Accolate)
- Always have your rescue inhaler with you at all times to help stop an asthma attack if it happens. Zafirlukast (Accolate) works to control your asthma over time; it doesn't help treat asthma attacks.
- Take zafirlukast (Accolate) every day even if you don't have any asthma symptoms. This medication works to improve your overall lung function in the long run.
- Take zafirlukast (Accolate) on an empty stomach at least 1 hour before or 2 hours after meals. Food can affect how much medication gets absorbed into your body, which can affect how well it works.
- Don't change the dose or stop taking zafirlukast (Accolate) or any of your other asthma medications without talking to your provider first. Your asthma symptoms might come back if it's not controlled well enough.
- Make sure to tell your provider and pharmacist about all the medications you're taking or planning to take. They can check for any potentially serious interactions with zafirlukast (Accolate) and adjust your medications to keep you safe.
Risks and warnings for Zafirlukast (Accolate)
Zafirlukast (Accolate) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Not a rescue inhaler for asthma attacks
While zafirlukast (Accolate) can control your asthma in the long run, it can't stop an asthma attack that's happening. Make sure to always have your rescue inhaler with you at all times so you can use it when these attacks happen. Continue taking zafirlukast (Accolate) as instructed by your provider if you have an asthma attack.
Liver damage
- Risk factors: History of liver problems
Though rare, some people taking zafirlukast (Accolate) have had liver damage. In most cases, signs and symptoms of liver damage went away when they stopped taking the medication. But in rare cases, liver damage worsened to life-threatening liver failure. Call your provider right away if you have upper right stomach pain, nausea, tiredness, yellowing of your skin or whites of the eyes, flu-like symptoms, or loss of appetite. These can be signs of liver damage.
Depression, changes in mood, and trouble sleeping

Symptoms can include intense itching, rash, worsened breathing problems, trouble breathing, tingling or numbness in hands or feet, and pain and swelling of your sinuses.

Tell your provider right away if you notice any of these symptoms during treatment.

Taking zafirlukast (Accolate) together with the blood thinner warfarin (Coumadin) can raise your risk of bleeding.
