A blockage in the lower urinary tract can either be related to enlargement of the prostate (benign prostatic hyperplasia) or a urethral stricture.
Colchicine is used to prevent or treat attacks of gout (also called gouty arthritis). This condition is caused by too much uric acid in the blood. An attack of gout occurs when uric acid causes inflammation (pain, redness, swelling, and heat) in a joint. Colchicine does not cure gout, but it will help prevent gout attacks. Colchicine is not an ordinary pain reliever and will not relieve most kinds of pain. Colchicine is also used to treat a rare condition called familial Mediterranean fever (FMF) in adults and children older than 4 years of age. Colchicine may be used in 2 ways.
If you're unable to take NSAIDs or if NSAIDs are ineffective, a medicine called colchicine can be used instead. Colchicine reduces some of the swelling and pain associated with a gout attack. It's best to have it with you at all times so you can use it at the first sign of a gout attack.
