Yes, the most severe interactions would occur with Sympathomimetics/Tricyclic Compounds
This applies to Albuterol which is compound similar to Clen:
snce albuterol may lower serum potassium concentration, care should be taken in patients also receiving other drugs that can lower serum potassium concentration, as the effects may be additive.The electrocardiographic changes and/or hypokalemia that may result from the administration of nonpotassium-sparing diuretics (such as loop or thiazide diuretics) may be aggravated by concomitant beta-agonists, especially when the recommended dosage of the beta-agonist is exceeded. Although the clinical importance of these effects is not known, caution is advised when administering beta-agonists with nonpotassium-sparing diuretics.
The manufacturers state that the effects of albuterol or levalbuterol on the vascular system may be potentiated in patients receiving monoamine oxidase inhibitors or tricyclic antidepressants; therefore, albuterol or levabuterol should be administered with extreme caution to patients receiving these drugs or within 2 weeks of discontinuation of such agents.
The action of albuterol or levalbuterol is antagonized by beta-adrenergic blocking agents (e.g., propranolol). beta-Adrenergic blocking agents not only block the pulmonary effects of beta-agonists, but may produce severe bronchospasm in asthmatic patients; therefore, asthmatic patients should not normally be treated with beta-adrenergic blocking agents. However, under certain circumstances (e.g., prophylaxis after myocardial infarction), there may be no acceptable alternatives to the use of beta-adrenergic blocking agents in patients with asthma; cardioselective beta-adrenergic blocking agents should be used with caution in these patients.
There is some evidence from animal studies that concomitant administration of a beta-adrenergic agonist (e.g., isoproterenol) and a methylxanthine (aminophylline) may produce increased cardiotoxic effects (e.g., cardiac arrhythmias, sudden death, myocardial necrosis). Although such an interaction has not been established in humans, a few reports have suggested that such a combination may have the potential for producing cardiac arrhythmias. Further accumulation of clinical data is needed to determine whether this potential interaction exists in humans.
So most antidepressant medication/ Harsh Diuretics/ other Beta-Agonists or stimulants.
