Key takeaways:
Albuterol (Ventolin HFA, ProAir RespiClick) inhalers are go-to treatments for relieving asthma symptoms, such as wheezing and shortness of breath. They are generally well tolerated and have a low risk of side effects.
Albuterol’s most common side effects include tremors, nervousness, and a fast heart rate. Other side effects, such as a runny nose, a sore throat, and trouble sleeping, can also happen.
Serious side effects from albuterol are rare. But if you have worsening breathing symptoms or an irregular heartbeat, go to the ER.

Albuterol (Ventolin HFA, ProAir RespiClick) is a short-acting beta agonist (SABA). SABAs are fast-acting medications that help open the airways in your lungs, making it easier to breathe. They’re commonly used to relieve asthma and chronic obstructive pulmonary disease (COPD) symptoms, such as wheezing and shortness of breath.
Albuterol is the most widely used SABA. It’s available as inhalers and nebulizer solutions. Inhalers are small and portable, making them convenient to carry. Nebulizers are another option and may be easier to use for some people. You may use one or both of them depending on the severity of your breathing symptoms.
But even though albuterol can be convenient and is generally well tolerated, there are some potential side effects to be aware of.

Here, we’ll dig deeper into nine notable albuterol side effects and what to expect if you use it.
1. Tremors
Tremors (shakiness), especially in the hands, are a temporary but common side effect of albuterol inhalers. They affect about 20% of people who use them. They are more common in children but can affect people of any age. Tremors happen because albuterol can temporarily activate receptors (chemical binding sites) in your body. These receptors increase nerve signals and affect body movements.
If tremors happen to you, you may be able to wait them out. They should subside with time. But if they continue to bother you or become more frequent, make sure to see a healthcare professional.
2. Nervousness or hyperactivity
Nervousness, anxiety, and increased excitement are also common side effects of albuterol inhalers. Up to 20% of people using albuterol may experience anxiety, nervousness, and increased excitement. In some cases, they can also contribute to insomnia symptoms.
These symptoms are more common in children ages 2 to 6. Thankfully, these short-term symptoms tend to be less of a problem.
3. Rapid heart rate
Using an albuterol inhaler may lead to a faster heart rate than normal. Heart palpitations (a pounding or racing heartbeat) are also possible.
For people without preexisting heart problems, this shouldn’t lead to long-term problems. But if you have high blood pressure (hypertension), diabetes, or another heart-related condition, you may want to ask a healthcare professional if you should monitor your heart rate more often or take other precautions.
4. High blood pressure
Albuterol inhalers can potentially contribute to high blood pressure and other heart-related problems. The medication primarily affects beta-2 receptors in your lungs. But these same receptors are also found in your heart. You may experience temporary changes in heart rate and blood pressure when albuterol affects these receptors.
If you’re living with high blood pressure or another heart-related condition, ask a healthcare professional before starting albuterol. They may want to brief you on warning signs to watch for and how to use caution with the medication.
5. Runny nose
Albuterol inhalers may cause or contribute to rhinitis (a runny nose). They can also lead to cold or allergy symptoms, such as a stuffy nose or sneezing.
If a runny nose is causing a stir, an over-the-counter (OTC) medication may be a good option. An antihistamine, such as loratadine (Claritin) or diphenhydramine (Benadryl), can help dry up your sinuses for temporary relief. A nasal spray such as Flonase (fluticasone propionate) could also help.
Before you try an OTC medication to help with your runny nose, it’s a good idea to ask your pharmacist.
6. Sore throat
Albuterol inhalers can sometimes irritate your throat, leading to soreness. This may happen when some of the medication lands in your mouth and throat instead of reaching your lungs.
One prevention strategy is using an inhaler spacer. This is a device you can attach to your inhaler to help better deliver medication into your lungs. Spacers can help more albuterol reach your lungs. You’ll get more of your intended dose, and less medication ends up in your mouth and throat. This can help reduce throat irritation. Ask a healthcare professional if an inhaler spacer is right for you.
Keep in mind: Not all albuterol inhalers are compatible with spacers. For instance, if you have a ProAir RespiClick inhaler, a spacer isn’t an option. Ask a pharmacist if you’re not sure whether you can use a spacer with your albuterol inhaler.
7. Worsening asthma or bronchospasm
In very rare cases, some people may notice worsening asthma symptoms after using an albuterol inhaler. This can seem strange — albuterol inhalers are meant to relieve asthma symptoms. If this happens, you may feel chest tightness, increased wheezing, or worsening shortness of breath. This unintended effect is called paradoxical bronchospasm.
If you experience any of these symptoms, stop using albuterol. Ask a healthcare professional immediately about next steps. You may need a prescription for a different medication.
8. Trouble sleeping
About 10% of people who use albuterol report difficulty sleeping. Similar to nervousness and hyperactivity, this occurs because albuterol can activate certain receptors in your nervous system.
This side effect is thought to be dose related. That means the more albuterol you use, the more likely you are to experience this side effect.
9. Low potassium
Albuterol can lower your potassium levels, potentially leading to hypokalemia. This in turn may cause an irregular heartbeat (arrhythmia), which can be dangerous. You may have a higher risk of developing hypokalemia if you use too much albuterol or take other medications that lower your potassium, such as a loop diuretic.
But this condition is usually temporary. In most cases, it doesn’t require supplementation with potassium.
Still, your prescriber may occasionally monitor your potassium levels.
How to limit the side effects of albuterol
There are several things you can do to help limit albuterol side effects:
Use albuterol exactly as prescribed. Taking extra doses of albuterol or using it more often than recommended can raise your risk of side effects. If your usual dose isn’t helping your breathing, tell your prescriber. This may be a sign that your treatment isn’t working well enough. They can help determine why albuterol isn’t working well. You may need a different treatment plan.
Make sure you’re using your albuterol device correctly. Whether you use an inhaler or a nebulizer, using your device correctly helps you get the intended dose of medication. Using your inhaler incorrectly may cause albuterol to land in your mouth, nose, and throat instead. This could make local side effects, such as a sore throat and runny nose, more likely. Guidelines recommend checking your inhaler technique regularly. If you use a nebulizer, make sure you know how to set it up and use it properly. Ask your pharmacist or prescriber to watch you use your albuterol device and correct any mistakes. If you have trouble using your device, your prescriber may be able to help you find a different type.
Keep your albuterol device clean. Cleaning your inhaler or nebulizer helps make sure the medication reaches your lungs. This may help limit local side effects, such as throat irritation, from medication collecting in your mouth and throat. If your device isn’t cleaned regularly, medication can build up and bacteria can contaminate it. Cleaning instructions vary by device, so follow the instructions that come with yours. Ask your pharmacist if you’re not sure how or how often to clean it.
Tell your prescriber about bothersome side effects. Don’t change your albuterol dosage or stop using albuterol on your own. Your prescriber can review your symptoms, check your device technique, and decide whether your treatment needs to be changed.
Who should not use albuterol inhalers?
You shouldn’t use albuterol if you’ve had a serious allergic reaction to albuterol or any of the ingredients in your product. Dry-powder albuterol inhalers, such as ProAir RespiClick, may contain milk proteins. So they shouldn’t be used if you have a severe milk protein allergy.
Children younger than the approved age for a specific albuterol product shouldn’t use it. Albuterol inhalers are approved for adults and children ages 4 and older. Albuterol nebulizer solution can be used in children as young as age 2, depending on the product. Talk to your child’s prescriber if you’re unsure whether an albuterol product is appropriate for their age.
Frequently asked questions
Because of interactions, you may need to avoid certain medications while using albuterol. Albuterol interactions include:
Other SABA inhaled medications, such as levalbuterol (Xopenex HFA)
Beta blockers, such as labetolol
Diuretics (“water pills”), such as furosemide (Lasix)
Monoamine oxidase inhibitors, such as phenelzine (Nardil)
Tricyclic antidepressants, such as amitriptyline
Digoxin (Lanoxin)
These interactions may make albuterol less effective or raise your risk of side effects, such as heart problems or low potassium levels. Ask your prescriber or pharmacist before combining these medications with albuterol.
No, albuterol isn’t considered a stimulant. It is a SABA, which works by activating beta receptors in your lungs. This relaxes the muscles around your airways and makes it easier to breathe.
But albuterol can cause some stimulant-like side effects, such as shakiness, nervousness, and a fast heart rate. These effects happen because albuterol can also affect beta receptors outside the lungs, especially at higher doses.
