About Karbinal ER

What is Karbinal ER?

Karbinal ER is the drug carbinoxamine in an extended-release formula. It is an antihistamine prescribed to treat a variety of ailments including colds, flu, allergic rhinitis (both seasonal and perennial), allergic conjunctivitis, and their symptoms such as runny nose, red, watery eyes, hives, rash, and itching. It may also be prescribed along with epinephrine in response to anaphylactic reactions. It works by neutralizing the effects of histamine in the body.

How do I take Karbinal ER?

Karbinal ER is administered as a liquid suspension that is taken orally on an as-needed basis, but not more frequently than every 12 hours. Shake the bottle thoroughly before dispensing. The exact amount will be determined by a doctor and will be governed by the condition being treated and the medical profile of the patient. Do not take more or less than the amount prescribed and do not administer it to children under 2 years of age.

What if I forget to take a dose of Karbinal ER?

Because Karbinal ER is taken on an as-needed basis, missing a dose is unlikely. However, if your doctor has you on a schedule, at least 12 hours must elapse between doses unless directed otherwise by a doctor. Do not increase the amount taken or alter the dosing schedule if one is missed.

What happens if I overdose on Karbinal ER?

If an overdose of the Karbinal ER drug occurs, contact Poison Control at 1-800-222-1222. If the individual has stopped breathing or lost consciousness, call Emergency Services at 911. Symptoms of an overdose may include hallucinations, extreme drowsiness or sleepiness, convulsions, dry mouth, dilated pupils, flushing, gastrointestinal problems, slowed or shallow breathing, or extreme agitation.
