) the use of this product is contraindicated. 4 Special warnings and precautions for use Clonidine Hydrochloride 25 mcg Tablets should be used with caution in patients with cerebrovascular disease, coronary insufficiency, heart failure, occlusive peripheral vascular disorders, such as Raynaud's disease, polyneuropathy, constipation or those with a history of depression.
At doses higher than those recommended above, Clonidine is an effective antihypertensive agent. Caution should therefore be observed where antihypertensive agents are being used, as potentiation of the hypotensive effect may occur. Provided the recommended clonidine dosage regimen is followed, no difficulty with hypotension should arise during the routine management of patients with either migraine or menopausal flushing.
Depending on the dose given, Clonidine Hydrochloride can cause bradycardia. In patients with pre-existing cardiac conduction abnormalities, arrhythmias have been observed after high doses of clonidine hydrochloride. Patients with renal failure require extreme care.
2). Patients should be instructed not to discontinue therapy without consulting their physician. Following sudden discontinuation of Clonidine after prolonged treatment with high doses, agitation, restlessness, palpitations, rapid rise in blood pressure, nervousness, tremor, headache or nausea have been reported.
When discontinuing therapy with Clonidine, the physician should reduce the dose gradually over 2-4 days. Patients who wear contact lenses should be warned that treatment with clonidine may cause decreased lacrimation. The use and the safety of clonidine in children and adolescents under 18 years have insufficient evidence in randomized controlled trials and therefore cannot be recommended for use in this population.
Serious adverse events, including sudden death, have been reported in concomitant use with methylphenidate. The safety of using methylphenidate in combination with clonidine has not been systematically evaluated. Excipients This medicine contains lactose.
