Levitra (Vardenafil) medicine belongs to the category called PDE5 inhibitors used in Erectile Dysfunction. It is not an aphrodisiac and does not increase sexual desire.

It is available in round shaped orange tablet with strengths of 10mg or 20mg.

Levitra is an oral tablet, which is swallowed. For Levitra to be effective, sexual stimulation is required.

Levitra 20 mg film-coated tablets are orange with the BAYER cross on one side and the strength (20) on the other side. The tablets are provided in blister packs containing 4, 8 or 12 tablets.

At least one in ten men has trouble getting or keeping an erection at some time. There may be physical causes or psychological causes, or most likely, a mixture of both. Whatever the cause, the effect is the same: muscle and blood vessel changes mean that not enough blood stays in the penis to make it hard and keep it hard.

You can take Levitra with or without food – but preferably not after a heavy or high-fat meal as this may delay the effect.

Erections are usually controlled by a balance of two body chemicals. The first brings on erections; the second takes erections away. If the two chemicals are out of balance, you can lose an erection before it starts.

Levitra works by reducing the action of the second chemical (called PDE-5). Levitra allows an erection to last long enough for you to satisfactorily complete sexual activity. It is taken about 25 to 60 minutes before sexual activity and it will only work when you are sexually stimulated.

How it works?

Levitra works by helping to relax the blood vessels in the penis and allowing blood to flow into the penis which causes an erection. Levitra will not give a man an erection spontaneously; it takes 25-60 minutes to get an erection if he is sexually stimulated. If the nerves or blood vessels associated with this process are not working properly, a man may not be able to get an erection. Levitra increases blood flow into the penis, so that when a man is sexually aroused, he can get and keep an erection. When the sexual encounter is over, the erection goes away.

Common Levitra Side Effects

Like all medicines, Levitra can cause side effects, although not everybody gets them. Most of the effects are mild or moderate.

How to make sure you have got Genuine Levitra?

When you buy Levitra, make sure the box is sealed and has a perforated tab to one side on the front of the box. It should also have a batch number and an expiry date, along with Bayer's address and their European registration number EU/1/03/248/010. Your Levitra box should also have brail across the front. Only if your box has all these things, can you be certain that it is genuine Bayer Levitra.

How to take Levitra?

Always take Levitra exactly as your Doctor has told you. You should check with your Doctor or pharmacist if you are not sure. The usual dose is 10 mg.
