Chlorpheniramine Tablets

Description

Chlorpheniramine Tablets contain chlorpheniramine maleate, a first generation antihistamine commonly used for dogs and cats.

Chlorpheniramine works by blocking the effects of histamine at H1 receptors. Histamine is released during allergic responses and contributes to signs such as itching and other allergy related reactions.

Chlorpheniramine is an over the counter antihistamine and does not require a prescription for purchase. When using chlorpheniramine for a pet, the appropriate amount and frequency should be based on the animal's species, body weight, individual needs, and veterinary guidance.

Some pets may experience drowsiness while taking chlorpheniramine. Individual responses to antihistamines can vary.

Brand, manufacturer, tablet appearance, packaging, and inactive ingredients may vary depending on product availability.

How It Works

Chlorpheniramine is a first generation H1 antihistamine.

It works by blocking histamine at H1 receptor sites. Histamine is one of the substances involved in allergic responses and contributes to many common allergy related signs.

By limiting the effects of histamine, chlorpheniramine provides antihistamine activity that may help support pets experiencing certain allergy related signs.

Individual responses to antihistamines vary, and some pets may respond differently than others.

Indications

Chlorpheniramine is an over the counter antihistamine commonly used in dogs and cats when antihistamine support is appropriate.

It may be used as part of an individualized approach for pets experiencing certain allergy related signs.

Veterinary uses of human labeled chlorpheniramine products are not specifically listed on the human OTC product label. Pet owners should use an appropriate amount for the individual animal and consult their veterinarian when unsure whether chlorpheniramine is appropriate for their pet.

Cautions

• Keep out of reach of children and animals.
• Use only plain chlorpheniramine unless another product has specifically been recommended for your pet.
• Do not substitute combination human cold or allergy products, as they may contain additional ingredients that are inappropriate for animals.
• Chlorpheniramine may cause drowsiness.
• Use cautiously in animals with glaucoma, urinary difficulties, gastrointestinal obstruction, cardiovascular conditions, high blood pressure, or certain respiratory conditions.
• Consult your veterinarian before use in pregnant, breeding, or nursing animals.
• Ask your veterinarian before combining chlorpheniramine with sedatives, tranquilizers, other antihistamines, or medications that may cause drowsiness.
• Do not use in animals with a known sensitivity to chlorpheniramine or similar antihistamines.
• Seek veterinary guidance if allergy related signs are severe, persistent, recurrent, or worsening.

Possible Side Effects

Some pets may experience side effects while taking chlorpheniramine.

Possible side effects may include:

• Drowsiness or sedation / Lethargy / Dry mouth / Vomiting / Diarrhea / Decreased appetite / Difficulty urinating / Changes in behavior or activity

Some animals may experience excitement rather than drowsiness.

Stop use and contact your veterinarian if significant or persistent side effects occur.

Seek prompt veterinary attention if an overdose is suspected or if your pet develops severe agitation, tremors, seizures, collapse, difficulty urinating, breathing difficulty, or another concerning reaction.

Precautions

Monitor your pet when first introducing chlorpheniramine so you can observe its individual response.

Because chlorpheniramine may cause drowsiness, use additional caution when it is combined with other products or medications that may have sedating effects.

Consult your veterinarian before use if your pet has glaucoma, urinary problems, gastrointestinal obstruction, cardiovascular disease, high blood pressure, thyroid disease, respiratory disease, liver disease, kidney disease, or another significant medical condition.

Do not use combination human cold or allergy medications in place of plain chlorpheniramine unless specifically recommended by your veterinarian. Combination products may contain additional active ingredients that are inappropriate for pets.

If allergy related signs persist, worsen, or are accompanied by facial swelling, breathing difficulty, collapse, or another severe reaction, seek veterinary attention promptly.
