| How does this drug work? | Viagra, Cialis and Levitra belong to a class of drugs known as PDE-5 (Phospodiesterase type 5) inhibitors. All three drugs work by blocking the enzyme (PDE5) which is found primarily in the penis. By inhibiting PDE5, the blood vessels in the penis remain relaxed for a longer period which allows for an increased blood flow. Another effect is the "holding" of blood in your penis helping to produce longer-lasting erections. All three treatments are NOT aphrodisiac's and only work when you are sexually aroused. | ||

Drugs Linked to Erectile Dysfunction
Many innocuous drugs can be linked to ED. There are also a number of prescription and over-the-counter drugs that may cause erectile dysfunction. While these medications may treat a disease or condition, in doing so they can affect a man's hormones, nerves, or blood circulation, resulting in ED or increase the risk of ED.Examples of medicines that may cause ED are listed below. During your medical questionnaire, it is important to tell your doctor about any drug (legal or illegal) that you are taking so that they have a full picture of your health.

If you experience ED and think that it may be a result of medication you are taking, do not stop taking the medication without first consulting your doctor. If the problem persists, your doctor may be able to prescribe a different medication.
Other substances or drugs that can cause or lead to ED include recreational and frequently abused drugs, such as:
- Alcohol
- Amphetamines
- Barbiturates
- Cocaine
- Marijuana
- Methadone
- Nicotine
- Opiates
Aside from the well-known complications that the use and abuse of these drugs can cause, ED is not often mentioned. However, use of these drugs can cause ED. These drugs not only affect and often times suppress the central nervous system, but can also cause serious damage to the blood vessels, resulting in permanent ED.
