How Does Levitra Work?
The active component in Levitra 20mg is vardenafil, a salt classified as a Phosphodiesterase Type-5 inhibitor (PDE5 inhibitor). PDE5 inhibitors work by opening up and dilating blood vessels, facilitating increased blood flow. Since the PDE5 enzyme is present in the corpora cavernosa of the penis, dilating the blood vessels here increases the amount of blood flowing to the penis, which helps in maintaining an erection and thus, helps people with erectile dysfunction.
Levitra, like other similar drugs, works only in the presence of nitric oxide, which is naturally released in the body when one feels aroused sexually. Thus, Levitra will only be effective in getting an erection in a state of sexual arousal.
Levitra 20 mg is taken as needed, and the maximum recommended dosage is once per day.
As needed dosage for Levitra usually starts from 10 mg but can be increased by your physician depending on your medical condition. The medicine usually takes about 1 to 2 hours to work and only works in a state of sexual arousal, so it should be taken accordingly before intercourse.
The optimal dose for each individual can vary, according to their lifestyles and other preexisting health conditions. A physician should be consulted to help suggest the ideal dose for you, to avoid any drug interactions.
What happens if I miss a dose?
Levitra 20 mg is usually taken as needed. Therefore, it is quite unlikely that you might miss a dose.
What happens if I overdose?
In no situation should you take more than the suggested dose, as it can lead to a painful condition called priapism, which is an erection for a prolonged period of time. The damage caused to the penis tissue by priapism may be permanent, so care should be taken to avoid an overdose. Taking more than the prescribed dose can also cause extremely low blood pressure, which can be fatal. Other issues caused by an overdose include severe dizziness or fainting. Seek immediate medical help in case of an overdose.
The side effects of Levitra are similar to those caused by other PDE5 inhibitors, which can be caused either by the drug’s reaction to the body or due to an interaction with another drug you may be taking for a preexisting condition. Some common side effects include but are not limited to:
- Upset stomach
- Indigestion, or dyspepsia
- Back pain
These side effects are quite common and will usually subside on their own once your body adjusts to the medication. Other serious side effects which are more concerning include:
- Priapism, or a painful and prolonged erection that lasts for more than 4 hours
- Reduced hearing or changes in vision
- Low blood pressure
- Heart attack symptoms, such as radiating pain in arms or jaw
