🔔 How should this medicine be used?
Pentamidine injection comes as powder to be mixed with liquid to be injected intramuscularly (into a muscle) or intravenously (into a vein) by a doctor or nurse in a medical facility. If it is given intravenously, then it is usually given as a slow infusion over 60 to 120 minutes. The length of treatment depends on the type of infection being treated.
A doctor or nurse will watch you closely while you are receiving the infusion and afterwards to be sure you are not having a serious reaction to the medication. You should be lying down while you receive the medication. Tell your doctor or nurse right away if have any of the following symptoms: dizziness or lightheaded feeling, nausea, blurred vision; cold, clammy, pale skin; or rapid, shallow breathing.
