Hello doc, my husband is on lonart at the moment and septrin was also mistakenly prescribed for him to treat malaria and typhoid. He has being itchin?

Lonart too can cause itching, but if he has been on it for some time and the dose is already reduced, then better stay on its course, septrin does seem to be the problem here, itching here is a blessing rather: lonart and septrin aren't a good combination and may cause problems with heart rythm. Other treatments for typhoid are available as amoxicillin or ceftriaxone, according to the case, .
