When you act on the decision to start taking Levitra, it is in your own interests to monitor how your body reacts. For example, among the possible side-effects are dizziness and blurred vision, so it would be unwise to drive your car or operate dangerous machinery until you are confident that there will be no danger to yourself and others. With Levitra, it is better not to drink alcohol at all, or if you cannot avoid it in a social context, drink only a little until you know how your body is likely to react. It is more common to experience adverse side-effects if you have mixed the drug with alcohol. You should also know that the side-effects are more common during hot weather or if you lead a very active sporting life. If any of these possibilities apply to you, make sure that you stand up or get out of bed slowly, otherwise dizziness or a loss of physical co-ordination may cause you an embarrassing fall. Finally, you should not take Levitra and eat grapefruit or drink grapefruit juice. There are chemicals in grapefruit that affect the rate at which you body absorbs a drug into the blood stream. It is safer not to mix Levitra with grapefruit in any form.
Clinical trials and increasing personal experience shows that most men can use Levitra without any adverse side-effects. If side-effects do come, they are usually mild and do not last long. The mild side-effects to look out for include:
- a flushing or blushing of the face or neck;
- a headache;
- an upset stomach, heartburn or nausea;
- cold symptoms of a stuffed-up or “runny” nose; or
- back pain.
Should you experience any of the following while engaging in sexual activity, stop immediately and call a doctor if:
- your erection is painful or lasts for an unnaturally long time;

- you hear a ringing sound in your ears or suddenly lose your hearing;
- you feel nausea, heavy sweating and have difficulty in breathing;
