MacroBID (Nitrofurantoin) is an antibiotic used to treat and prevent infections of the bladder, kidney and other parts of the urinary tract. MacroBID is a prolonged release capsule, which should be taken at meal times with food or milk. Like all antibiotics, it is vital that the full 3 day course is completed, to prevent antibiotic resistance.
This medication is not recommended for diabetics, and must be avoided if you are pregnant or breast feeding. While taking MacroBID, your urine may become dark yellow or brown. This is quite normal and not a reason to stop taking the medicine.
Uses / Instructions
One capsule to be taken twice a day for a course of three days. MacroBID should be taken with food or milk. Capsules should be swallowed whole.
Talk to your doctor, pharmacist or nurse before taking MacroBID:
- if you have diabetes
- if you are suffering from any illness causing severe weakness
- if you have anaemia (a decrease in red blood cells causing pale skin, weakness and breathlessness); a lack of vitamin B or abnormal levels of salts in your blood (your doctor will be able to advise you)
- if you have a history of allergic reactions
- if you have any problems with your kidneys.
The above conditions may increase the chance of developing a side effect which causes damage to the nerves, altered sense of feeling, like pins and needles.
- if you lack an enzyme (body chemical) called glucose-6-phosphate dehydrogenase, which causes your red blood cells to be more easily damaged (this is more common in black people and people of Mediterranean, Middle Eastern or Asian origin. Your doctor will know)
- if you have any disease of the lungs, liver or nervous system. If you need to take MacroBID for a number of months, your doctor may want to regularly check how your lungs and liver are working
- if you have false positive results on testing your urine for glucose
- if you have urine coloured yellow or brown
- If you experience fatigue, yellowing of the skin or eyes, itching, skin rashes, joint pain, abdominal discomfort, nausea, vomiting, loss of appetite, dark urine, and pale or gray-colored stools. It may be symptoms of liver disorder.
