Frenin Injection 1 ml belongs to a class of medications called anti-hypotensives used to treat hypotension (low blood pressure) caused by spinal anaesthesia, circulatory failure or certain other medicines. Also, it is used to treat low blood pressure during surgery or after an injury. Hypotension is a condition in which the blood flows through the blood vessels at lower than normal pressures. Low blood pressure symptoms include tiredness, dizziness, light-headedness, loss of consciousness, nausea, depression, blurry vision, or clammy (wet or sweaty) skin.

Frenin Injection 1 ml contains Phenylephrine that works by constricting and narrowing blood vessels by acting on alpha receptors. Thus, it increases blood pressure and decreases heart rate.

Frenin Injection 1 ml will be administered by a healthcare professional; do not self-administer. In some cases, you may experience headache, vomiting, sweating, nervousness, tremor, shortness of breath, difficulty in passing urine or irregular heartbeat. Most of these side effects of Frenin Injection 1 ml do not require medical attention and gradually resolve over time. However, if the side effects persist, please consult your doctor.
