Watery eyes, sneezing, nasal congestion, itchy skin and chest tightness indicate more than just a minor irritation as these symptoms can signal the onset of an allergy. According to the Mayo Clinic, allergies affect the skin, airways and digestive tract. An anaphylactic reaction, a condition characterized by trouble breathing, hives and facial, tongue or throat swelling, can occur if severe allergies go untreated.
Brompheniramine
Brompheniramine is a medication that belongs to the class of drugs called antihistamine medications. It works to block the action of histamine, so that the typical allergy symptoms (coughing, sneezing, itchy eyes and runny nose) do not occur.
Drugs.com says that brompheniramine's side effects include fatigue, dizziness, dry mouth and a headache. It can also cause trouble urinating, difficulty sleeping and increase the chances for developing a enlarged prostate. Signs of an allergic reaction to brompheniramine include trouble breathing, hives and tongue or facial swelling.
Taking brompheniramine while having asthma, a stomach ulcer, bladder problems, an enlarged prostate, heart problems, an overactive thyroid gland or glaucoma may require changes in brompheniramine's dose. Sometimes, brompheniramine cannot be taken as it may worsen these conditions.
The regular and liquid tablet is typically taken every four to six hours as needed, according to Drugs.com. The extended-release capsule is taken every 8 to 12 hours as needed.
