In fact, if you have asthma, you should avoid taking nyquil altogether.

Some of the ingredients in nyquil can cause your airways to become more inflamed, which is especially dangerous if you also have asthma. That makes nyquil especially risky for people with asthma.

Nyquil can also suppress your immune system, which makes you more susceptible to contracting infections. If you have asthma, you already have a weaker immune system than someone without asthma. Therefore, you’re more likely to contract an infection if you’re taking nyquil.

Why is nyquil dangerous for people with inhalers?


The main issue with taking nyquil is that it can decrease the effect of your inhaler. That’s because certain ingredients in nyquil can interfere with the way your body absorbs medications.

That means if you take nyquil and a medication in your inhaler, the amount of the medication in your body could drop dramatically. That can be dangerous if you need your inhaler to treat a chronic disease like asthma. In some cases, it can be fatal if you take nyquil while using an epinephrine inhaler.

If you have asthma, it’s best to avoid taking nyquil altogether.

If you have another chronic lung disease, it’s important to talk to your doctor to see if nyquil is safe for you.
