How To Take Antihistamines

Does Benadryl help dogs?

Depending on your symptoms, you can take antihistamines:

  • Every day, to help keep daily symptoms under control
  • Only when you have symptoms
  • Before being exposed to things that often cause your allergy symptoms, such as a pet or certain plants

For many people with allergies, symptoms are the worst around 4 a.m. to 6 a.m. Taking an antihistamine at bedtime may help you or your child feel better in the morning during allergy season.

So What Is The Best Allergy Medication

As described above, there are a few things to consider when selecting the right allergy medication. How quickly you need relief, your symptoms, side effects, and cost can all factor into your decision.

Fast-acting medications like decongestants and antihistamines work quickly if youre experiencing symptoms. And while antihistamines can be taken daily, decongestants should only be used as needed short term.

Antihistamines and intranasal steroids can be good options for preventing symptoms from happening if taken daily before allergy season hits. Experts currently recommended intranasal steroids as first-choice treatment for people with persistent symptoms.

Lastly, keep in mind that not all antihistamines are created equal Benadryl can make you feel drowsy, whereas Allegra and Claritin may be less sedating. Since all antihistamines may cause some drowsiness, its best to see how you respond to them before engaging in activities that require alertness or concentration.

How Are Antihistamines Classified

Antihistamines are divided into two major subtypes. The first subtype is called H-1 receptor antagonists or H-1 blockers. This subtype of antihistamines is used to treat allergy symptoms. The second subtype is called H-2 receptor antagonists or H-2 blockers. They are used to treat gastrointestinal conditions, including gastroesophageal reflux disease , peptic ulcers, gastritis, motion sickness, nausea and vomiting. The naming structure tells doctors and scientists the cell type the location of the histamine receptor that the antihistamine medication blocks.

The H-1 blocker subtype is further broken down into two groups first-generation antihistamines and second-generation antihistamines.

Antihistamines counteract the effect of histamine throughout the body, and treat a range of symptoms including itching, hives, sneezing, and runny nose.

Benadryl® Allergy Liqui

Some medicines may interact with antihistamines, increasing the side-effects of either or both medicines. Usually it is better to avoid taking antihistamines at the same time as certain medicines, including:

  • Certain types of antidepressants. Tricyclic antidepressants such as amitriptyline and lofepramine may interact with antihistamines. Other antidepressants such as moclobemide.
  • Antacids, which may interfere with the way the antihistamine is absorbed, thus making it less effective.
  • Other tablets which make you drowsy, as the combination may be too much. For example opioid painkillers or benzodiazepines and Z drugs.
  • A group of medicines called antimuscarinics. This includes medicines such as hyoscine, oxybutynin, propantheline and tolterodine. Because these medicines can give you similar side-effects, such as a dry mouth or problems passing urine, the combination may make the side-effects more serious.

If you are buying your antihistamine from a pharmacy, make sure you tell the pharmacist if you take other medicines so they can advise accordingly.

Also watch the ingredients in other over-the-counter treatments. For example, remedies for coughs and colds may contain antihistamines, in which case you might end up taking double the dose by mistake.
