What is the Pill with the Imprint 'N006'?
The white, round pill marked with the imprint 'N006' has been identified as Hydroxyzine Hydrochloride 50 mg. It is a prescription-only medication. The pill is typically 9mm in size. Correctly identifying medication is the first step toward safe and effective use. If you have a pill that you cannot identify, always consult a pharmacist or physician.
Pharmacology and Mechanism of Action
Hydroxyzine Hydrochloride belongs to a drug class called antihistamines and is also considered a miscellaneous anxiolytic, sedative, and hypnotic. Chemically, it is unrelated to benzodiazepines (like Xanax), phenothiazines, or meprobamate. Its primary mechanism of action involves preventing the effects of a substance called histamine, which the body produces during allergic reactions. Its sedative and anti-anxiety effects may be due to the suppression of activity in certain key regions of the subcortical area of the central nervous system. Clinical effects are typically noticeable within 15 to 30 minutes after oral administration.
Primary Medical Uses
Healthcare providers prescribe Hydroxyzine (N006) for several conditions:
- Anxiety and Tension: It is used for the symptomatic relief of anxiety and tension associated with nervous and emotional conditions.
- Allergic Reactions: It is effective in managing pruritus (itching) caused by allergic conditions such as chronic urticaria (hives) and atopic or contact dermatoses.
- Sedation: It can be used as a sedative before medical procedures or after general anesthesia to help produce sleep and control anxiety.
- Nausea and Vomiting: The medication is also indicated for treating nausea and vomiting in some cases.
Safe Administration
The administration of Hydroxyzine is based on the patient's condition and response to therapy. It is crucial to take this medication only as prescribed by your doctor and not to adjust the dose without consultation.
Potential Side Effects and Warnings
Like all medications, Hydroxyzine can cause side effects, which are usually mild and temporary.
Common Side Effects:
- Drowsiness
- Dizziness
- Dry mouth
- Blurred vision
- Constipation
Serious Side Effects:
- QT Prolongation: Hydroxyzine may affect heart rhythm, a condition known as QT prolongation, which can be serious. This risk is higher in patients with pre-existing heart conditions or those taking other drugs that also prolong the QT interval.
- Involuntary Motor Activity: Tremors and convulsions have been reported, usually with doses higher than recommended.
- Mental/Mood Changes: Some individuals may experience restlessness, confusion, or hallucinations.
If you experience any serious side effects, seek medical attention immediately.
Drug Interactions to Be Aware Of
Hydroxyzine can have a potentiating (strengthening) effect when used with other central nervous system (CNS) depressants. Therefore, caution is essential.
- CNS Depressants: The dosage of narcotics, non-narcotic analgesics, and barbiturates should be reduced when taken with hydroxyzine.
- Alcohol: Patients should be advised against the simultaneous use of alcohol, as its effects may be increased.
- Other Antihistamines: Do not use with other antihistamines, including topical products like diphenhydramine cream, as this can increase side effects.
