What is Buy Blue Viagra 250 mg (Sildenafil 250 mg)?
Blue Viagra 250 mg (Sildenafil 250 mg). Sildenafil is used to treat erectile dysfunction, a medical condition in which a man cannot get, or keep, a hard erect penis suitable for sexual activity.
The first and most important precaution involves nitrate drugs, including prescription drugs used for angina, which are taken in a variety of different ways: under the tongue, in pills, skin patches, through inhalers, or intravenously. The precaution also applies to the “recreational” use of inhaled nitrates, often referred to as “poppers.” This warning applies to all nitrates and all ED pills, and the rule is simple: they don’t mix. The problem is a potentially life-threatening fall in blood pressure. Men should not take a nitrate within 24 hours of using Viagra or Levitra or within 48 hours of taking Cialis, which stays in the body longer than the others.
Another concern is the potential interaction between ED pills and the alpha blockers used for benign prostatic hyperplasia (BPH). Although ED and BPH are separate entities, both conditions are common, especially in older men. The main worry is low blood pressure, but it’s a much greater concern with the older alpha blockers terazosin (Hytrin, generic) and doxazosin (Cardura, generic) than with the newer, uroselective medications tamsulosin (Flomax), alfuzosin (UroXatral), and silodosin (Rapaflo). The best advice for men with BPH and ED is to use a uroselective alpha blocker in the lowest dose that will control BPH symptoms, and then after a stable dose is established, to carefully begin using an ED pill, starting with the lowest dose and gradually increasing it if needed. Tadalafil appears less likely to interact with alpha blockers than other ED pills. It seems prudent for men who use both types of medications to take them at separate times, perhaps six hours apart.
A number of other medications can elevate blood levels of the ED pills by inhibiting the enzymes that normally remove the ED medication from the body. One is the popular acid-suppressing drug cimetidine (Tagamet, generic), which is available over the counter as well as by prescription. The others include several prescription antibiotics (erythromycin, clarithromycin) and HIV medications.
Side Effects
Possible viagra side effects include nausea, dizziness, headache, flushing, dyspepsia, abnormal vision, nasal congestion, back pain, myalgia, nausea, dizziness, rash, diarrhoea, insomnia and fatigue.
The most common side effect of sildenafil, found in Viagra, is headache. Pfizer, the company that first created sildenafil, reports that headache occurs in around 16 percent of patients.
Flushing, also known as vasocongestion, is another side effect of viagra , occurring around 10 percent of the time. It is generally characterized as the change in body temperature and color due to increases in blood flow to specific areas of the body.
viagra may also cause digestive problems such as indigestion and diarrhea. The effects on the gastrointestinal system are dose dependent, and higher doses are not recommended for patients with pre-existing digestive complications.
