Side Effects:

- Drowsiness or sedation: Due to its sedating properties, drowsiness is the most common side effect, which can affect your ability to perform tasks that require mental alertness, such as driving.
- Dry mouth or throat irritation: This may occur due to the drying effect of antihistamines.
- Dizziness or lightheadedness: Some people may experience dizziness or a feeling of lightheadedness, especially when standing up quickly.
- Blurred vision: This is a less common side effect but may occur due to its anticholinergic effects.
- Nausea or stomach upset: Some individuals may experience mild gastrointestinal discomfort.
- Constipation: Due to the drying effect on mucous membranes, constipation may occur.
In rare cases, more severe side effects may occur, including:
- Confusion or hallucinations: Particularly in older adults or those taking high doses.
- Rapid heartbeat or palpitations: May indicate an adverse reaction to the medication.
- Urinary retention: Difficulty urinating, especially in elderly men with prostate problems.
If you experience any severe side effects or symptoms of an allergic reaction (such as swelling, difficulty breathing, or rash), discontinue use immediately and seek medical attention.
Contraindications:
Diphenhydramine (HISTAZYN) 50mg Capsule should be used with caution or avoided in the following conditions:
- Allergy to Diphenhydramine: If you have a known allergy to Diphenhydramine or any other ingredients in the syrup, avoid using this product.
- Severe liver or kidney disease: People with severe liver or kidney conditions may need a lower dose or an alternative treatment.
- Acute asthma or respiratory problems: While Diphenhydramine can help with allergic rhinitis, it is not suitable for individuals with acute asthma or other respiratory conditions, as it may worsen symptoms.
- Glaucoma: Antihistamines can increase intraocular pressure, so individuals with narrow-angle glaucoma should avoid using this medication.
- Prostate issues: Due to its anticholinergic properties, this medication may cause urinary retention in individuals with enlarged prostate or bladder obstruction.
- Breastfeeding: Diphenhydramine is excreted in breast milk, so it is not recommended for breastfeeding mothers unless prescribed by a healthcare provider.
- Children under 2 years: This product is not recommended for infants, as they are more sensitive to the sedative effects of antihistamines.
- Alcohol consumption: Avoid alcohol while using this medication, as it can increase drowsiness and other side effects.
Warnings and Precautions on Diphenhydramine (HISTAZYN) 50mg Capsule:
- Drowsiness: Since Diphenhydramine can cause drowsiness, do not operate heavy machinery, drive, or engage in activities that require full alertness after taking this medication.
- Avoid combining with other sedatives: Avoid using other sedative medications, including alcohol, benzodiazepines, or other antihistamines, as they may enhance the sedative effect.
- Overdose risk: Taking too much Diphenhydramine can lead to serious health complications such as seizures, hallucinations, and heart issues. If overdose is suspected, seek medical help immediately.
- Pregnancy: Consult your healthcare provider before using this medication during pregnancy. Although Diphenhydramine is classified as a Category B medication (generally considered safe), it is always best to use caution during pregnancy.
