Different types of antihistamines?
Generally, antihistamines have been classified into two groups:
First-generation or sedating antihistaminescan cause significant drowsiness and are generally more associated with the antimuscarinic side-effects. These include alimemazine, clemastine, cyproheptadine, hydroxyzine, ketotifen and promethazine. These medicines may be used for their sedative effects should your sleep be disturbed by itching.
Non-sedating or second-generation antihistaminesare newer medicines which generally cause less drowsiness. However, anyone taking these medicines while performing skilled tasks – for example, driving – should be aware that a sedative effect may still occur and, in particular, in combination with alcohol. Second-generation antihistamines include acrivastine, cetirizine, desloratadine, fexofenadine, levocetirizine and loratadine and Chlorpheniramine.
Which is the best one?
All antihistamines work pretty well to reduce symptoms of allergy. Your healthcare provider may advise or prescribe a particular antihistamine depending on the cause of your allergy and on whether you require a sedating or non-sedating medicine. For example:
In general, antihistamines are probably roughly equally effective in reducing the symptoms of hay fever (seasonal allergic rhinitis) and hives (urticaria). However, non-sedating antihistamines tend to be used more commonly as they cause less drowsiness.
Second-generation antihistamines are generally advised for most allergic situations as they cause less drowsiness.
Cetirizine, fexofenadine, or loratadine are often recommended for urticaria.
Antihistamine eye drops may be advised when itchy eyes are a particular problem – for example, azelastine eye drops or ketotifen drops. Opcon-A is the best choice!
A sedating antihistamine should never be used at bedtime for children who have allergic symptoms. Cough medicines containing sedating antihistamines are not suitable for children under the age of 6 years, and a healthcare provider needs to advise for children between the ages of 6 and 12 years. More children die under the age of 2 from antihistamines than any other medication. Just because it is sold on the shelf does not mean it is safe to use.
For other conditions, specific antihistamines may be used. For example, cyclizine and promethazine teoclate are used for feeling sick (nausea) and being sick (vomiting), not for hay fever. Chlorphenamine is the antihistamine most used in an emergency situation such as anaphylaxis, and may be given by injection in this situation. Diphenhydramine (Nytol®) is sold over the counter as a sleep remedy. Never use Diphenhydramine, ever! If you are on blood pressure medications or any cardiac conditions, stoke, psych meds, COPD or congestive heart failure medications. Just to name a few. NEVER!

Prescription Drugs And Erectile Dysfunction: 5 Drugs Keeping Men Down
These five categories of drugs may cause erectile dysfunction.
Most men who take prescription medications know that they’re going to come with a list of side effects, which usually include drowsiness, headaches, dry mouth, or upset stomach. Sometimes, they’re a bit more serious, encompassing everything from skin irritation to allergic reactions and anaphylactic shock. But most of these guys forget one of the more unwanted side effects: erectile dysfunction.
Around the country, erectile dysfunction, or simply ED, affects as many as 30 million men, according to the Department of Health and Human Services. Though this figure probably doesn’t include all those men taking prescription meds, they certainly experience the same effects, such as anxiety, depression, low self-esteem, and a decreased quality of life. Nevertheless, it’s important to know which medications may cause these side effects, and speak to a doctor about possible alternatives — or just prepare to have trouble keeping it up. Here are five of them.
It’s interesting that benzodiazepines, which are commonly used for anxiety — but also seizures and insomnia — can cause ED, and thus further anxiety. In fact, you’ll find that it’s a running theme. Anxiety is well known to cause ED, as increased levels of stress harm the body and take away from a man’s libido.
Though common benzodiazepines, such as Xanax, Ativan, Valium, and Librium, may help calm a man’s anxieties through sedative effects, they may also end up lowering a man’s desire to have sex, as well as his ability to stay erect.
Another condition that causes ED in itself, major depression affected an estimated 16 million adults in 2012. Antidepressants are also used to treat anxiety disorders, obsessive compulsive disorder, and even long-term pain. One of the major forms of antidepressants, called selective serotonin reuptake inhibitors (SSRIs), are comprised of the drugs Celexa, Prozac, Zoloft, and Lexapro.
Up to 60 percent of people taking SSRIs may experience ED, according to Medscape. Though it’s unclear how it causes ED, experts suspect it relates to the way the drugs influence function of the neurotransmitters serotonin, norepinephrine, and dopamine, all of which relate to feelings of well-being.
High blood pressure damages blood vessels, including those in a man’s penis; causing ED. But beta blockers, one of the drugs most commonly prescribed to people who have blood pressure, may also cause them to experience ED. Drugs that fall into this category include Sectral, Lopressor, Cogard, and Tenormin.
Just like antidepressants, these drugs also affect neurotransmitters in the brain, specifically epinephrine (adrenaline). In this particular case, they counteract the stimulatory effects of the molecule, tamping down on a person’s excitement. At the same time, some evidence suggests beta blockers also messes with the areas of a man’s nervous system that make him erect.
Millions of men suffer from allergies, but some of the most common drugs, such as Benadryl and Dramamine, may be causing them to have ED, too. Though it’s unclear exactly how it causes ED, personal accounts of its effects suggest that it could alter the way men’s nervous systems react to stimulation around the penis. It also seems to be temporary, with sensation coming back gradually after ending use.
Also called H2-receptor antagonists, this category of drugs include the popular heartburn drugs Zantac and Pepcid. They’re used to treat gastrointestinal disorders like gastric ulcers, erosive esophagitis, and gastroesophageal reflux disease.
For the most part, they cause ED when taken in high doses, and the drug Tagamet (cimetidine) is most likely to give men problems. Along with Ed and a decreased libido, they can also lower a man’s sperm count.
Though life on these drugs may seem grim within the sexual arena, taking them is important for treating whatever disease a doctor has prescribed them for. Also, by talking with a doctor about alternative treatments, lowering doses, or taking supplements, anyone who takes these drugs may be able to get some of their sexual health back.
So what do you do?
As always give us a call. The answer to many of the symptoms described here, which started someone on the cycle of various prescriptions, can be treated and reversed with other ways. Taking a chemical to treat a symptom is only going to cause more problems for you.
