Side effects of drugs for potency Q&A

Check out the answers to the most frequently asked questions about drugs to improve potency.

Why do Cialis, Viagra and Levitra have the same side effects?

Viagra, Cialis and Levitra are part of the PDE5 enzyme inhibitor group and work on the same principle of relaxing smooth muscle cells that dilate blood vessels in the penis. Therefore, they all have similar side effects.

How long do side effects last?

When the pills are taken correctly, the side effects are relatively mild and most disappear after a few hours.

Do PDE5 inhibitors affect vision?

Indeed, in rare cases, some men experience temporary mild visual problems: mainly a blue tint of perception, as well as increased sensitivity to light and blurring of the objects in question. Read more about the effect of Viagra on vision read here. Also, patients with retinitis pigmentosa, a rare eye disease, should be very careful when using these drugs.

Can Viagra cause blindness?

In 2005, there were reports that Viagra was associated with another rare eye disease, non-arteritic anterior ischemic optic neuropathy, which can lead to blindness. However, as of 2006, fewer than 50 such cases were known compared to the millions of men who used erection drugs without problems. However, these facts serve as a reminder to patients over 50 of the need for regular examinations by an ophthalmologist in case of any vision problems that occur after taking Viagra, Levitra or Cialis.

Do drugs for potency affect hearing?

Sudden hearing loss is another rare side effect of potency pills and represents a possible risk of using Viagra, Cialis or Levitra. A 2007 US study found that this type of temporary hearing loss is almost always unilateral, meaning it only affects one ear.

How do Viagra, Cialis and Levitra affect blood pressure?

A few hours after taking a PDE5 inhibitor tablet, blood pressure tends to decrease slightly: the upper (systolic) value drops by 8-10 mmHg, and the lower (diastolic) by 5-6 mmHg.< /p>

Why is it dangerous to take PDE5 inhibitor pills and nitroglycerin at the same time?

It is very important to avoid taking Viagra, Cialis and their analogues at the same time as drugs containing nitrates, which also lower blood pressure. An example is nitroglycerin. Interactions between these two types of drugs can cause a life-threatening drop in blood pressure.

I use nitroglycerin for resorption, can I take Viagra or Levitra?

Do not use sublingual (sublingual) tablets or nitroglycerin spray within 24 hours after taking Viagra or Levitra. For Cialis, this ban extends to 48 hours.

Do PDE5 inhibitors interact with nitrates in vegetables?

Nitrates and nitrites present in foods are not dangerous when taking Viagra, Cialis, Levitra and similar drugs.

Only nitrates cannot be combined with erection pills?

Men who take medications known as a1-blockers should also be careful. These drugs, which include doxazosin (Cardura), terazosin (Hytrin), and tamsulosin (Flomax), are used to treat high blood pressure.

How long after taking a1-blockers can I take Viagra or Cialis?

If you are taking these blood pressure medications, ask your doctor before taking any pills that are PDE5 inhibitors. For example, Viagra should not be taken within four hours of taking an alpha blocker.

Which gastric medicines are undesirable to use with potency pills?

Another common drug that interacts with PDE5 inhibitors is cimetidine (Tagamet), used to treat severe heartburn and stomach ulcers. Cimetidine slows down the breakdown of erection-improving drugs, so it can effectively double the level of Viagra, Levitra, or Cialis in the bloodstream, which is fraught with overdose and unwanted side effects.Because of this, users taking Tagamet must use a lower dose of Viagra and its analogues. No side effects have been reported from taking the drugs together, but the risk may be higher.
