Hi, thanks for asking from HCM. I can understand your concern. As you are getting relief after taking medication, you should not discontinue medicine without consulting doctor. Regarding side effects, each allopathy medicine has some side effects, so medicine should be changed only if ineffective or causing serious side effects. I am mentioning side effects of both medication. You can go through it and consult doctor regarding change in medication only if you develop intolerable side effect Side effects of Clonafit beta (Clonazepam) : Dizziness : Poor concentration : Malaise, general weakness, muscular pain : Poor co-ordination : Increased salivation, urination : blurred vision : Impotence Famocid 20 (Famotidine) : Nausea, vomiting : Dizziness : Impotence : Constipation or diarrhoea : Allergy : Muscular pain or myalgia Change medicine only if serious or intolerable side effects. Otherwise continue both drugs. Hope it will help you. Thanks, take care. Dr ishu Bishnoi
