Can i take 2 antihistamines a day?

Antihistamines are some of the most commonly used drugs in the world today. They come in handy when you need to relieve symptoms like sneezing, coughing or itching caused by allergies, hay fever or colds. But just how safe is it to take two antihistamines a day? This article takes an in-depth look at this question, so buckle up and let’s get started!

The basics of antihistamines

Before we delve into the issue at hand (taking two antihistamines a day), here’s some basic information about what these drugs are and how they work.

Antihistamines are medications that help alleviate allergy symptoms such as sneezing, itchiness, hives etc., by blocking histamine receptors within your body. Histamine is a hormone-like molecule produced naturally by your immune system which plays several roles including triggering inflammatory responses within the body.

Different types of antihistamines exist on the market today- first-generation (old-fashioned) antihistamines and second-generation ones. First-generation(1G) ones were invented decades ago while Second-generations(2Gs) have been around since mid-1980s.

How first-generation antihistamines work

First-gen antimuscarinics bind with muscarinic acetylcholine receptors throughout your central nervous system(CNS). The other older generation has serotonergic&histaminergic effects which cause drowsiness -hence often labeled ”sedating”.

Common examples include Chlorpheniramine (Chlor-Trimeton); Diphenhydramine(Benadryl); Doxylamine(Unisom).

Facts about Second Generation Antidepressants

Second generation “non-sedating” H1-receptor antagonists read through medically accepted studies have been shown to be effective as their parent 1G antihistamines without inducing excessive sleepiness.

Newer drugs in the market now include Loratadine(Clarityn); Cetirizine(Zyrtec) and Fexofenadine(Allegra).

Taking Antihistamines

While it’s very tempting to reach for your antihistamine when you notice allergies or symptoms related. However, it is important that you do not think of them as harmless candies!

One in a day- Is it mandatory?

If used correctly following directions laid out on drug labels& doctor’s advice, most people can safely take one dose of an antihistamine every 24 hours. This will vary slightly based on drug/HSA though. To achieve maximal safety outcomes stick to the prescribed amount.

Not all allergic reactions require use of these medications always contact your general practitioner for medical advise & recommendations before taking any medication daily.

But what about Two doses

This specific question has two possible answers: short answer, no; long answer – It depends!

Your health status may play major role here..

Here are some cases where double dosing maybe considered:

Case 1: Medical Opinion recommends double dosage

Some healthcare providers might suggest that doubling up on doses especially during severe allergy attacks when one dose does not prove enough symptom relief hourly intervals may be required if instructed by physician

Do NOT apply self-medication! Follow the exact instructions indicated by physicians/hospital staff members

Case 2: Accidental overdose situation

In case of accidental ingestion follow emergency steps described below depending on severity reported/symptoms presented i.e
”drowsiness”, “shallow breathing”, ”extreme dizziness,” ‘hallucinations’.

I hope this doesn’t happen but Stay Alert!

Antidepressant toxicity can become rapid within minutes so quickly ACT call numbers “911” or poison control centres.

Antihistamine Overdose- What to do

Some of the signs& symptoms presented during antihistamine overdose include:
– Shaking or tremors
– Dilated pupils, dry mouth, flushed skin
– Fast/irregular heartbeat palpitations
– Blurred vision and disorientation/slurring speech pronounced.
If encountered prevention by taking other medications concurrently can be done such as charcoal pills s prescribed but at a maximum of 2 doses within hours. Read-the-instructions & follow them.

Understanding therapeutic range,

When considering dose escalation for effectiveness on your symptoms always remain cognizant that doubling needless might lead to unwanted side effects while diminishing efficacy chances.
Consulting with health care practitioners before making determinative decisions leads to understanding necessary precautions

Nowadays new Types H3 histamin inbitors possibly may provide alternative solutions for future allergic reactions relief especially if traditional ones fail to yield positive results.

Conclusion
