How to use Dicycloverine

What the official label says. If a doctor prescribed it, follow the prescription. Your pack's leaflet comes first if it is different.

Who it is for

Cycloserine is indicated in the treatment of active pulmonary and extrapulmonary tuberculosis (including renal disease) when the causative organisms are susceptible to this drug and when treatment with the primary medications (streptomycin, isoniazid, rifampin, and ethambutol) has proved inadequate. Like all antituberculosis drugs, cycloserine should be administered in conjunction with other effective chemotherapy and not as the sole therapeutic agent. Cycloserine may be effective in the treatment of acute urinary tract infections caused by susceptible strains of gram-positive and gram- negative bacteria. …

How to take it and how often
  • Cycloserine is effective orally and is currently administered only by this route
  • The usual dosage is 500 mg to 1 g daily in divided doses monitored by blood levels. 1 The initial adult dosage most frequently given is 250 mg twice daily at 12-hour intervals for the first 2 weeks
  • A daily dosage of 1 g should not be exceeded
Talk to a doctor first if

Administration is contraindicated in patients with any of the following: • Hypersensitivity to cycloserine • Epilepsy • Depression, severe anxiety, or psychosis • Severe renal insufficiency • Excessive concurrent use of alcoho

Warnings

Administration of cycloserine should be discontinued or the dosage reduced if the patient develops allergic dermatitis or symptoms of CNS toxicity, such as convulsions, psychosis, somnolence, depression, confusion, hyperreflexia, headache, tremor, vertigo paresis, or dysarthria. The toxicity of cycloserine is closely related to excessive blood levels (above 30 mcg/mL), as determined by high dosage or inadequate renal clearance. The ratio of toxic dose to effective dose in tuberculosis is small. The risk of convulsions is increased in chronic alcoholics. Patients should be monitored by hematologic, renal excretion, blood level, and liver function studies.

Possible side effects

Most adverse reactions occurring during therapy with cycloserine involve the nervous system or are manifestations of drug hypersensitivity. The following side effects have been observed in patients receiving cycloserine: Nervous system symptoms (which appear to be related to higher dosages of the drug, i.e., more than 500 mg daily) • Convulsions • Drowsiness and somnolence • Headache • Tremor • Dysarthria • Vertigo • Confusion and disorientation with loss of memory • Psychoses, possibly with suicidal tendencies • Character changes • Hyperirritability • Aggression • Paresis • Hyperreflexia • Paresthesia • Major & minor (localized) clonic seizures • Coma Cardiovascular: Sudden development of c …

If you take too much

Signs and Symptoms: Acute toxicity from cycloserine can occur if more than 1 g is ingested by an adult. Chronic toxicity from cycloserine is dose related and can occur if more than 500 mg is administered daily. The central nervous system is the most common organ system involved with toxicity. Toxic effects may include headache, vertigo, confusion, drowsiness, hyperirritability, paresthesias, dysarthria, psychosis paresis, convulsions, and coma. …

If you miss a dose

Take it when you remember, unless it is nearly time for the next dose. Then skip the missed one. Never take two doses at once to make up for it. Check your leaflet, as some medicines are different.
