PHENAMIN INJECTION belongs to the class of drugs called antihistamines used to prevent or treat symptoms of allergic conditions such as hay fever (seasonal allergies), allergic skin reactions such as itching or hives (itchy, raised bumps on the skin), allergic conjunctivitis (redness and irritation in the membrane that covers the eye) and other types of allergy. Also, it is used to prevent and treat nausea and vomiting after surgery due to certain types of anaesthesia and motion sickness. Additionally, PHENAMIN INJECTION is used in postoperative, preoperative and obstetric (during labour) sedation. An allergy occurs when foreign elements, known as allergens, attack and invade our body, thereby causing the release of histamine (a chemical messenger) that causes swelling, inflammation, redness, itchiness, and watery nose and eyes.

PHENAMIN INJECTION contains Promethazine, an antihistamine (anti-allergic drug) that works by blocking the action of histamine, a substance responsible for causing allergic reactions. It helps relieve allergy symptoms such as sneezing, running nose, watery eyes, itching, swelling, and congestion or stiffness. Also, it blocks the histamine receptors in the vomiting centre in the brain and prevents nausea and vomiting. Additionally, Promethazine possesses sedative effects and helps you feel relaxed before and after surgery. 

PHENAMIN INJECTION will be administered by a healthcare professional; do not self-administer. PHENAMIN INJECTION may cause common side effects such as drowsiness, dizziness, tiredness, incoordination, lack of energy, increased blood pressure or occasional low blood pressure. Most of these side effects do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.

If you are known to be allergic to Promethazine or any other medicines, please tell your doctor. If you are pregnant or breastfeeding, inform your doctor before receiving PHENAMIN INJECTION. PHENAMIN INJECTION is not recommended for use in children below two years of age and in dehydrated children. Avoid alcohol consumption while receiving PHENAMIN INJECTION as it may increase drowsiness and decrease mental alertness. Avoid driving if you experience any side effects that impair your physical or mental abilities after receiving PHENAMIN INJECTION.

It blocks the action of histamine, a substance responsible for causing allergic reactions. Thereby, it helps to provide relief from symptoms of allergy. Also, it blocks the histamine receptors in the vomiting centre in the brain and prevents nausea and vomiting after surgery due to certain types of anaesthesia and motion sickness. Additionally, Promethazine possesses sedative effects and helps you feel relaxed before and after surgery. Thus, it is used in postoperative, preoperative and obstetric (during labour) sedation. PHENAMIN INJECTION may be used to treat a symptom of Parkinson’s disease known as oculogyric crises (uncontrolled rolling of eyeballs).

If you are known to be allergic to Promethazine or any other medicines, please tell your doctor. If you are pregnant or breastfeeding, it is advised to inform your doctor before receiving PHENAMIN INJECTION. PHENAMIN INJECTION is not recommended for children below two years of age and in dehydrated children. Avoid alcohol consumption while receiving PHENAMIN INJECTION as it may increase drowsiness and decrease mental alertness. Avoid driving if you experience any side effects that impair your physical or mental abilities after receiving PHENAMIN INJECTION. You may be advised to postpone skin allergy tests as PHENAMIN INJECTION may suppress the reaction to the test allergens. PHENAMIN INJECTION may give false positive or false negative results on pregnancy tests. Also, it may interact with blood sugar tests and not yield accurate results. Therefore, before undergoing any tests, please inform your doctor or lab technician that you are on treatment with PHENAMIN INJECTION.

Allergies:

• Regularly wash your hands with soap and water to prevent the spread of germs.
• Eat plenty of foods rich in good bacteria, like yoghurt, to improve overall health.
• Drink plenty of fluids to avoid dehydration.
• Gargle with salt water for relief from sore throat.
• Avoid consumption of alcohol with PHENAMIN INJECTION as it may cause tiredness, drowsiness or lack of concentration.

Nausea and vomiting:

• Eat a healthy low-fat diet, especially in small portions, as it will be easy to digest. Avoid eating over-sweet food and include more salty food, especially if you have been vomiting.
• Drink any other liquid at least 30 minutes after eating food. 
• If the smell of the food makes you feel sick (vomit), do not cook food, as it may worsen your condition. Let someone else do the cooking or use prepared food from the freezer.

Allergy: It occurs when foreign elements/allergens attack and invade our body, thereby causing the release of histamines. This chemical messenger 'histamine' causes swelling, inflammation, redness, itchiness, itchy/watery nose and throat, and watery eyes. Allergies generally occur due to chemicals, air pollution, pet danders, dust, pollen hairs, seasonal allergies like hay fever etc.

Nausea and vomiting: Nausea is a feeling of uneasiness in the stomach that often comes before vomiting. On the other hand, vomiting is the forcible voluntary or involuntary emptying of stomach contents through the mouth. In short, nausea and vomiting are not diseases but are symptoms of many conditions like infections, motion sickness, an early stage of pregnancy, and gastroparesis (slow stomach emptying). A receptor located in the brain known as the chemoreceptor trigger zone (CTZ) controls vomiting.
