Indoramin

Caution should be observed in prescribing indoramin for patients with hepatic or renal insufficiency.

Alcohol can increase both the rate and extent of absorption of indoramin, but no untoward effects have been reported at recommended doses.

Concomitant use of indoramin with antihypertensive drugs or drugs with hypotensive properties e.g. antidepressants, anxiolytics, hypnotics and moxisylyte, may enhance their hypotensive action. Titration of dosage of the latter may therefore be needed.

Caution should be observed in prescribing indoramin for patients with a history of depression.

The 'Intraoperative Floppy Iris Syndrome (IFIS, a variant of small pupil syndrome) has been observed during cataract surgery in some patients on or previously treated with tamsulosin. Isolated reports have also been received with other alpha-1 blockers and the possibility of a class effect cannot be excluded. As IFIS may lead to increased procedural complications during the cataract operation current or part use of alpha-1 blockers should be made known to the ophthalmic surgeon in advance of surgery.

A few cases of extrapyramidal disorders have been reported in patients treated with indoramin. Caution should be observed in prescribing indoramin in patients with Parkinson’s disease.

In animals and in the one reported case of overdose in humans, convulsions have occurred. Due consideration should be given, and great caution exercised in the use of indoramin in patients with epilepsy.

Animal experiments indicate no teratogenic effects but indoramin tablets should not be prescribed for pregnant women unless considered essential by the physician.

There are no data available on the excretion of indoramin in human milk, but the drug should not be administered during lactation unless in the judgement of the physician such administration is clinically justifiable.

Drowsiness is sometimes seen in the initial stages of treatment with indoramin or when dosage is increased too rapidly. If drowsiness occurs, patients should be warned not to drive or operate machinery and to avoid CNS depressants including alcohol.

Drowsiness or sedation can occur on starting treatment with indoramin, and also if dosage is increased too rapidly. Less commonly, dry mouth, nasal congestion, weight gain, dizziness, failure of ejaculation, depression, fatigue, headache and hypotension (including postural hypotension) with or without syncope may occur.

Rarely, Parkinson’s disease could be exacerbated.

Rarely, hypersensitivity reactions including rash and pruritus may occur.
