For allergies the average oral dose is 25 mg taken before retiring; however, 12.5 mg may be taken before meals and on retiring, if necessary. Single 25 mg doses at bedtime or 6.25 to 12.5 mg taken three times daily will usually suffice. After initiation of treatment in children or adults, dosage should be adjusted to the smallest amount adequate to relieve symptoms. The administration of Promethazine HCl in 25 mg doses will control minor transfusion reactions of an allergic nature.

<!--Contraindications-->
|contraindications=
*Promethazine hydrochloride tablets are contraindicated for use in [[pediatric]] patients less than two years of age.
*Promethazine hydrochloride tablets are contraindicated in comatose states, and in individuals known to be [[hypersensitive]] or to have had an [[idiosyncratic]] reaction to promethazine or to other phenothiazines.
*[[Antihistamines]] are contraindicated for use in the treatment of [[lower respiratory tract]] symptoms including [[asthma]].
<!--Warnings-->
|warnings=
*CNS Depression
:*Promethazine HCl tablets may impair the mental and/or physical abilities required for the performance of potentially hazardous tasks, such as driving a vehicle or operating machinery. The impairment may be amplified by concomitant use of other central-nervous-system depressants such as alcohol, sedatives/hypnotics (including barbiturates), narcotics, narcotic analgesics, general anesthetics, tricyclic antidepressants, and tranquilizers; therefore, such agents should either be eliminated or given in reduced dosage in the presence of promethazine HCl (see PRECAUTIONS: Information for Patients and Drug Interactions).
*Respiratory Depression
:*Promethazine HCl tablets may lead to potentially fatal respiratory depression.
:*Use of promethazine HCl tablets in patients with compromised respiratory function (e.g., COPD, sleep apnea) should be avoided.
*Lower Seizure Threshold
:*Promethazine HCl tablets may lower seizure threshold. It should be used with caution in persons with seizure disorders or in persons who are using concomitant medications, such as narcotics or local anesthetics, which may also affect seizure threshold.
*Bone-Marrow Depression
:*Promethazine HCl tablets should be used with caution in patients with bone-marrow depression. Leukopenia and agranulocytosis have been reported, usually when promethazine HCl has been used in association with other known marrow-toxic agents.
*Neuroleptic Malignant Syndrome
:*A potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) has been reported in association with promethazine HCl alone or in combination with antipsychotic drugs. Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac dysrhythmias).
:*The diagnostic evaluation of patients with this syndrome is complicated. In arriving at a diagnosis, it is important to identify cases where the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever and primary central nervous system (CNS) pathology.
:*The management of NMS should include 1) immediate discontinuation of promethazine HCl, antipsychotic drugs, if any, and other drugs not essential to concurrent therapy, 2) intensive symptomatic treatment and medical monitoring, and 3) treatment of any concomitant serious medical problems for which specific treatments are available. There is no general agreement about specific pharmacological treatment regimens for uncomplicated NMS.
:*Since recurrences of NMS have been reported with phenothiazines, the reintroduction of promethazine HCl should be carefully considered.
*Use in Pediatric Patients
:*Promethazine Hcl tablets are contraindicated for the use in pediatric patients less than two years of age.
:*Caution should be exercised when administering promethazine hcl tablets to pediatric patients 2 years of age and older because of the potential for fatal respiratory depression. Respiratory depression and apnea,sometimes associated with death, are strongly associated with promethazine products and are not directly related to individualized weight-based dosing, which might otherwise permit safe administration, concomitant administration of promethazine products with other respiratory depressants has an association with respiratory depression, and sometimes death, in pediatric patients.
:*Antiemetics are not recommended for treatment of uncomplicated vomiting in pediatric patients, and their use should be limited to prolonged vomiting of known etiology. The extrapyramidal symptoms which can occur secondary to promethazine hcl tablets administration may be confused with the CNS signs of undiagnosed primary disease, e.g., encephalopathy or reye's syndrome. The use of promethazine hcl tablets should be avoided in pediatric patients whose signs and symptoms may suggest Reye's syndrome or other hepatic diseases.
:*Excessively large dosages of antihistamines, including promethazine HCl tablets in pediatric patients may cause sudden death. Hallucinations and convulsions have occurred with therapeutic doses and overdoses of promethazine HCl in pediatric patients. In pediatric patients who are acutely ill associated with dehydration, there is an increased susceptibility to dystonias with the use of promethazine HCl.
*Other Considerations
:*Administration of promethazine HCl has been associated with reported cholestatic jaundice.
====Precautions====
*Drugs having anticholinergic properties should be used with caution in patients with narrow-angle glaucoma, prostatic hypertrophy, stenosing peptic ulcer, pyloroduodenal obstruction, and bladder-neck obstruction.
*Promethazine HCl tablets should be used cautiously in persons with cardiovascular disease or with impairment of liver function.

Promethazine Hcl tablets are contraindicated for the use in pediatric patients less than two years of age.
Caution should be exercised when administering promethazine hcl tablets to pediatric patients 2 years of age and older because of the potential for fatal respiratory depression. Respiratory depression and apnea,sometimes associated with death, are strongly associated with promethazine products and are not directly related to individualized weight-based dosing, which might otherwise permit safe administration, concomitant administration of promethazine products with other respiratory depressants has an association with respiratory depression, and sometimes death, in pediatric patients.
Antiemetics are not recommended for treatment of uncomplicated vomiting in pediatric patients, and their use should be limited to prolonged vomiting of known etiology. The extrapyramidal symptoms which can occur secondary to promethazine hcl tablets administration may be confused with the CNS signs of undiagnosed primary disease, e.g., encephalopathy or reye's syndrome. The use of promethazine hcl tablets should be avoided in pediatric patients whose signs and symptoms may suggest Reye's syndrome or other hepatic diseases.
Excessively large dosages of antihistamines, including promethazine HCl tablets in pediatric patients may cause sudden death. Hallucinations and convulsions have occurred with therapeutic doses and overdoses of promethazine HCl in pediatric patients. In pediatric patients who are acutely ill associated with dehydration, there is an increased susceptibility to dystonias with the use of promethazine HCl.
Other Considerations
Administration of promethazine HCl has been associated with reported cholestatic jaundice.
