thank-you user for your query I understand your concernBasically corex syrup contains Chlorpheniramine maleate, which is an H1-blocking antihistamine, relieves histamine-induced allergic edema of respiratory mucosa. Codeine acts by suppressing the cough centre in medulla which thereby helps in reducing excessive frequency and intensity of cough. The commonest side effects related to corex intoxication is short term memory loss, sleeplessness, tremors and spasms and long term addiction as in your case might cause serious kidney damage or constipation. Now the best part is that yes you still can get rid of this addiction by gradually reducing the intake of syrup and taking tramadol thrice daily initially and then reduce it to once daily at the end of a week. Don t worry you can consult any psychiatrist and he will make you to get relieved of its addiction. One more concern of yours needs answering that corex syrup might causes few sexual dysfunction but not at all it is related with infertility. So even after withdrawal you can still lead a normal fertile sexual life. god bless
