    Concomitant Use with Levodopa

    When ARTANE (Rodenal) is used concomitantly with levodopa, the usual dose of each may need to be reduced. Careful adjustment is necessary, depending on side effects and degree of symptom control. An ARTANE (Rodenal) dosage of 3 to 6 mg daily, in divided doses, is usually adequate.

    Idiopathic Parkinsonism

    As initial therapy for parkinsonism, 1 mg of ARTANE (Rodenal) in tablet or elixir form may be administered the first day. The dose may then be increased by 2 mg increments at intervals of three to five days, until a total of 6 to 10 mg is given daily. The total daily dose will depend upon what is found to be the optimal level. Many patients derive maximum benefit from this daily total of 6 to 10 mg, but some patients, chiefly those in the postencephalitic group, may require a total daily dose of 12 to 15 mg.


    ARTANE (Rodenal) may impair mental and/or physical abilities required for performance of hazardous tasks, such as operating machinery or driving a motor vehicle. Patients should be cautioned about operating machinery, including automobiles, until they are reasonably certain that ARTANE (Rodenal) therapy does not adversely affect their ability to engage in such activities.

    Because of increased sedative effects, patients should be cautioned to avoid the use of alcohol or other CNS depressants while taking ARTANE (Rodenal) .

    Since this medication may increase the susceptibility to heat stroke (gastrointestinal (GI) problems, fever, heat intolerance), use with caution during hot weather. (See WARNINGS.)

    Patients should be advised to report the occurrence of GI problems, fever, or heat intolerance promptly since paralytic ileus, hyperthermia, or heat stroke may occur.

    If GI upset occurs, ARTANE (Rodenal) may be taken with food.

    Patients should have close monitoring of intraocular pressure. (See WARNINGS.)

Dosage warnings

  • Your doctor should always start you on a low dosage of Rodenal and slowly increase your dosage as needed, especially if you’re aged 60 years or older. Increasing the dosage slowly will lower your risk of side effects.
  • Do not stop taking Rodenal abruptly. You can have a quick return of your symptoms and possibly develop a life-threatening condition called neuroleptic malignant syndrome.

Disclaimer: Our goal is to provide you with the most relevant and current information. However, because drugs affect each person differently, we cannot guarantee that this list includes all possible dosages. This information is not a substitute for medical advice. Always speak with your doctor or pharmacist about dosages that are right for you.


Baclofen is somewhat less effective than Rodenal in most children, but can be helpful in diminishing pain due to dystonia. It can provide additional benefit with used in combination with Rodenal. A typical starting dose is 5 mg at bedtime. The dose should be increased slowly until desired benefit or side effects occur. The usual maintenance dose is 10–60 mg/day in the three divided doses, but some older children obtain maximum benefit at doses as high as 180 mg/day. The most common side effect is sedation. Sudden cessation can precipitate seizures or psychosis and should be avoided.

In patients with good benefit from oral baclofen, but who cannot tolerate the effective dose due to side effects, intrathecal baclofen may be an option. There are few data available on the use of intrathecal baclofen in genetic dystonias and benefit may be limited. 136,137 Intrathecal baclofen is used more widely in children with dystonic cerebral palsy than in other forms of dystonia. It may be beneficial, but there is also a high rate of complications, including a 10% risk of infection. 138 A double-blind, placebo-controlled trial of intrathecal baclofen for children with dystonia CP is currently in progress. 139

Neuroleptic Malignant Syndrome

A potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) has been reported in association with dose reduction or discontinuation of Rodenal. Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac dysrhythmias).

The diagnostic evaluation of patients with this syndrome is complicated. In arriving at a diagnosis, it is important to identify cases where the clinical presentation includes both serious medical illness (eg, pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system (CNS) pathology.

Can Rodenal cause problems?

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with Rodenal. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects usually improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
