Side effects of salbutamol you should know.

Salbutamol is a commonly used medication that belongs to the drug class of short acting beta 2 agonists.

It is frequently used to relieve bronchospasm in conditions such as asthma and chronic obstructive pulmonary disease.

Although it is generally well tolerated, salbutamol can cause several side effects, including the following.

Tremors. One of the most common side effects. You may notice mild shaking, particularly in the hands.** **

Increased heart rate, also known as tachycardia.

Headache. Salbutamol can sometimes cause headache, restlessness, or a feeling of being jittery.

Muscle cramps. These can occur, particularly with higher doses or frequent use.

Low potassium levels, also called hypokalemia. High doses of beta 2 agonists can shift potassium into cells, causing hypokalaemia.

Rarely, salbutamol can cause paradoxical bronchospasm, where breathing suddenly becomes worse after inhalation. This requires urgent medical attention
