The drug impairs signals between the testes (testicles), pituitary gland, and hypothalamus of the brain. The blockage of communication can lead to a steep drop in testosterone and an increased risk of ED. The opioids most commonly linked to ED include: CodeineDilaudid (hydromorphone)Demerol (meperidine)FentanylMethadoneMorphineOxycontin (oxycodone) Parkinson's Disease Drugs Parkinson's disease is treated with drugs known as anticholinergics that block the chemical acetylcholine and dopamine agonists that increase the effects of dopamine. Parkinson's is thought to be caused by an imbalance of acetylcholine and dopamine. By altering the action of these neurotransmitters, the excitatory nerves in the penis may be impaired. At the same time, a lack of acetylcholine can prevent the dilation (widening) of blood vessels, making it difficult to achieve an erection. The medications that can cause ED in people with Parkinson's include: Artane (trihexyphenidyl)Cogentin (benztropine)Kemadrin (procyclidine)LevodopaParlodel (bromocriptine) Over-the-Counter Drugs That Cause Erectile Dysfunction Several over-the-counter drugs can cause or contribute to erectile dysfunction. Chief among these are antihistamines. These not only include antihistamines used specifically to treat allergies but also those classified as H2 blockers that function as antacids. Antihistamines block the action of histamine, a chemical in the body that is involved both in allergic reactions and the regulation of stomach acid. What many people do not realize is that histamine also helps relax smooth muscles, allowing the blood vessels in the penis to engorge. The overuse of antihistamines may lead to erection problems, particularly in those with other risk factors for ED. OTC antihistamines and H2 blockers closely associated with ED include: Antivert (meclizine)NizatidineBenadryl (diphenhydramine)Dramamine (dimenhydrinate)Pepcid (famotidine)Tagamet (cimetidine) In addition to OTC antihistamines, prescription antihistamines like promethazine and Vistaril (hydroxyzine) are also linked to ED.Sudafed and Erectile DysfunctionThe OTC decongestant Sudafed (pseudoephedrine) can also cause ED by increasing adrenaline levels in the blood. When this happens, blood vessels will constrict (narrow) rather than dilate (widen), making it harder for the penis to fill with blood. Recreational Drugs That Cause Erectile Dysfunction Recreational drugs, both legal and illegal, can cause erectile dysfunction in different ways. Some impair signals to and from the brain that facilitate erections. Others affect blood pressure or cause the narrowing of blood vessels, both of which restrict the flow of blood to the penis. Recreational drugs that increase the risk of ED include: AlcoholAmphetamines, including crystal methBarbiturates, such as phenobarbital and Seconal (secobarbital)CocaineHeroinMarijuanaNicotine Other Drugs That Cause Erectile Dysfunction The National Institutes of Health lists other common and uncommon drugs linked to ED. These include prescription medications and certain supplements that can reduce testosterone levels when overused. In addition to the above-listed drugs, there are other medications that can potentially cause erection problems, including: Amicar (aminocaproic acid)Androcur (cyproterone)Atromid-S (clofibrate)Atropen (atropine)Avodart (dutasteride)Compazine (prochlorperazine)Dilantin (phenytoin)Furoxone (furazolidone)Flexeril (cyclobenzaprine)Imitrex (sumatriptan)Indocin (indomethacin)Lanoxin (digoxin)Licorice supplementsNorpace (disopyramide)OrphenadrineProscar (finasteride)Reglan (metoclopramide)Statin drugs, like Crestor (rosuvastatin) and Pravachol (pravastatin) Managing Erectile Dysfunction Caused by Drugs There are times when medications (or medication doses) can be changed because of ED and others when they can't. If medications are the cause of your ED, you
