Although Viagra rarely displays any serious side effects or other reactions, it’s recommended to stop having sex in case you experience dizziness, nausea and numbness or tingling in your jaw, neck or arms when having sex. Some people may be recommended to avoid having sex at all as this may mean putting too much strain on their heart. In some very rare case Viagra can be a risk factor for developing sudden vision loss. This has to do with a sudden decrease of blood flow to the optic nerve of the eye. While it’s not clear if Viagra is to be blamed, or it’s simply one of several risk factors (being older than 50, smoking, being diagnosed with high blood pressure, high cholesterol or diabetes etc), you will need to be careful and always discuss your treatment with a qualified health care professional before you go online and buy Viagra there. Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. During sexual activity, if you become dizzy or nauseated, or have pain, numbness, or tingling in your chest, arms, neck, or jaw, stop and call your doctor right away.
You could be having a serious side effect of Viagra. Stop using Viagra and call your doctor at once if you have any of these serious side effects: priapism, general ill feeling, vision changes, irregular heartbeat, fainting, chest pain, swelling in your hands, ankles, or feet, shortness of breath, lightheadedness, sudden vision loss, and sudden hearing loss. However, in most cases only mild side effects are likely to occur. They may indicate your dose of Viagra needs to be adjusted, or that your body just needs some more time to adjust to the dose prescribed. If your mild side effects go away on their own (something most likely to happen), there is no need to tell your health care provider about them. However, if they change in intensity and get very bothersome or severe – it’s best to discuss this situation with your health care provider. The following mild side effects are reported most often: memory problems, back pain, warmth or redness in your face, headache, upset stomach, and stuffy nose. Other reactions are also possible, as Viagra can be tolerated in different ways by different people. You will need to watch for any signs of serious side effects during the first couple of times of using Viagra to make sure your dose is correct and doesn’t need to be adjusted.
