How many drops per minute for slow intravenous infusion?
Slow intravenous infusion typically involves about 25 drops per minute. The specific details are as follows:
Slow intravenous infusion is a method of intravenous administration, usually used when it's necessary to maintain a stable blood concentration of a drug or to reduce adverse drug reactions. For medications such as penicillin and cephalosporins, which are prone to cause allergic reactions, slow infusion is generally required so that any allergic reaction can be promptly detected and managed. Similarly, drugs like heparin and cardiac glycosides also require slow infusion to maintain a stable blood concentration. For medications requiring slow infusion, doctors usually adjust the infusion rate to approximately 25 drops per minute. In such cases, specialized infusion devices—such as micro-infusion sets or infusion counters—are needed to ensure accurate dosing and safety.
Patients must not arbitrarily adjust the infusion speed during intravenous administration, as doing so may affect both the drug’s efficacy and safety. If symptoms such as dizziness, nausea, or palpitations occur, medical advice should be sought immediately.
