Teldrin  : Uses, Side Effects, Interactions & More

Why is this medication prescribed?
Teldrin (Chlorpheniramine) relieves itchy, red, watery eyes; itchy sneezing in the nose or throat; and runny nose caused by allergies, hay fever, and the common cold. Teldrin helps control cold or allergy symptoms, but it does not treat the cause of the symptoms or speed recovery. Teldrin belongs to a class of medications called antihistamines. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms.

How should this medicine be used?
Teldrin (Chlorpheniramine) comes in tablets, capsules, extended-release (long-acting) tablets and capsules, chewable tablets, and a liquid to take by mouth. Regular capsules and tablets, chewable tablets, and liquid are usually taken every 4 to 6 hours, as needed. Extended-release (long-acting) tablets and capsules are generally taken twice daily in the morning and in the evening, as needed. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Teldrin exactly as directed. Do not take more or less or take it more often than prescribed by your doctor.

Teldrin comes alone and in combination with fever and pain reducers, expectorants, cough suppressants, and decongestants. Ask your doctor or pharmacist about which product is best for your symptoms. Carefully check the labels on over-the-counter cough and cold medicines before using 2 or more products at the same time. These products may contain the same active ingredients and taking them together could cause you to overdose. This is especially important if you are giving a child cough and cold medicine.

Over-the-counter combination cough and cold products, including products containing Teldrin, can cause serious side effects or death in young children. Do not give these products to children under the age of 4. If you are giving these products to children ages 4 to 11, be careful and follow the directions on the package carefully.

If you are giving a child Teldrin or a combination product containing Teldrin, read the package label carefully to make sure it is the right product for a child of that age. Do not give Teldrin products that are made for adults to children.

Before giving a child a Teldrin product, check the package label to see how much medicine the child should receive. Give the dose that matches the child’s age in the table. Ask your child’s doctor if he doesn’t know how much medicine to give him.

If you are taking the liquid, do not use a household spoon to measure your dose. Use the measuring spoon or cup that comes with the medicine or use a specially made spoon to measure the medicine.

If you are using the extended-release tablets or capsules, swallow them whole. Do not break, crush, chew, or open them.
