Phenergan is a medication that contains the active ingredient promethazine hydrochloride. It is an antihistamine used to treat a variety of conditions, including allergies, nausea, and vomiting.
The standard dosage of Phenergan (promethazine hydrochloride) for adults is 25 mg taken orally, 2-3 times a day. The dosage for children may vary depending on their age, weight, and medical condition. It is important to follow the instructions provided by the healthcare provider or as indicated on the packaging.
Phenergan is available in tablet, syrup, and suppository form. The tablet is taken by mouth with a glass of water. It may be taken with or without food, although taking it with food may help to reduce stomach upset. The duration of treatment may vary depending on the condition being treated.
Phenergan works by blocking histamine receptors in the body, which reduces the symptoms of allergic reactions such as itching, sneezing, and runny nose. It also has a sedative effect, which can be useful in treating insomnia or anxiety.
Possible side effects of Phenergan include drowsiness, dizziness, dry mouth, constipation, blurred vision, and difficulty urinating. It may also cause more serious side effects such as breathing difficulties, seizures, and allergic reactions. If any of these side effects occur, medical attention should be sought immediately.
Phenergan should not be used by individuals who are allergic to promethazine or other antihistamines, have a history of seizures or epilepsy, or are taking certain medications such as sedatives or tranquilizers. It may also interact with other medications, so it is important to inform the healthcare provider of any other medications being taken.
Overall, Phenergan is an effective medication for treating a variety of conditions, including allergies, nausea, and vomiting. However, it is important to follow the recommended dosage and to be aware of the possible side effects and contraindications. It is always best to consult with a healthcare provider before starting any new medication.
