I think it can cause hyperkalemia, or an excess of potassium. "Symptoms are fairly nonspecific, and generally include malaise, palpitations and muscle weakness; mild breathlessness may indicate metabolic acidosis, one of the settings in which hyperkalemia may occur." (

Further, "While salbutamol is well-tolerated, particularly when compared with previous therapies such as theophylline, like all medications there exists the potential for adverse drug reactions to occur - especially when in high doses, or when taken orally or intravenously.
Common adverse effects include: tremor, palpitations and headache. (Rossi, 2004)
Infrequent adverse effects include: tachycardia, muscle cramps, agitation, hypokalemia, tinnitus, hyperactivity in children, and insomnia." (

So while your symptoms may not be directly related to immunodeficiency caused by clenbuterol, some of your symptoms may be explainable through the physiological effects of the drug.
