Chloramphenicol

The use of this drug is contraindicated because the use of chloramphenicol will increase the effect of Sildenafil by affecting the patient hepatic and intestinal enzyme metabolism.

Isosorbide dinitrate

The use of this drug is contraindicated because the combination of this drug either increases the effects of the other by vasodilation which leads to fatal hypotension.

Nitroprusside sodium

The use of this drug is contraindicated because the combination of this drug either increases the effects of the others by pharmacodynamic synergism.

Enzalutamide

Use alternative drugs because the use of enzalutamide will decrease the effect of Sildenafil by affecting patient hepatic and intestinal enzyme metabolism.

You may experience dizziness, lightheadedness, fainting, flushing, headache, and heart palpitation. Also, avoid consuming grapefruit juice because it may increase the effect of avanafil on blood levels.

Drug-Disease Interaction

Cardiovascular disease:

The use of phosphodiesterase-5 enzyme inhibitors is contraindicated in patients with cardiovascular disease. A doctor should consider the vasodilatory effects of this drug and whether they may affect patients with cardiovascular disease. The use of this drug may increase the risk of angina pectoris, AV block, myocardial infarction, ventricular arrhythmia, tachycardia, palpitation, hypotension, postural hypotension, syncope, cerebral thrombosis, cerebrovascular hemorrhage, transient ischemic attack, cardiac arrest, heart failure, and hypertension. These events can occur during or after sexual activity.

Renal dysfunction:

What is Sildenafil?

Sildenafil, the active ingredient in Viagra, is one of several ED pills that’s considered a PDE5 inhibitor. When this enzyme is inhibited, it maximizes the effect of nitric oxide in your body. (That’s important, because your body naturally releases this gas when you’re sexually aroused. So it’s key to the process of getting and maintaining an erection.)

With more nitric oxide in play, the muscles around your penis can relax. In turn, blood flow to your penis improves. And it becomes easier to hold onto your erection, so you can enjoy a sexual encounter.

Sildenafil also works quickly. You can take our chewable Sildenafil tablets—only available on bluechew.com—about one hour before sex. Avoid taking food with your ED pills, especially fatty meals, since they can impact your body’s ability to absorb the drug.

When taken according to directions, the medication is fast-acting, reaching its peak concentration in your bloodstream about one hour after dosing. Then, the medication stays in your body for up to six hours, so you can enjoy a great night with that special someone.

Does that Medicine Affect My Health?

Depending on your ED medication, sildenafil can have side effects that are similar to or different than those that can be experienced by all people who takes it. For example, it may cause fatigue while taking it.

What Should I Avoid While Taking Sildenafil?

You can avoid potentially dangerous interactions with other drugs with which you’re familiar, such as nitrates, as it can cause a drop in blood pressure that could lead to dizziness or fainting. Additionally, you should avoid taking sildenafil with nitrates, as they can lead to dangerous low blood pressure.

You should also avoid taking sildenafil with any other drugs that can affect the synthesis of cGMP (cyclic guanosine monophosphate). Synthetic cGMP is produced by certain cells in the body, so it’s synthesis by your body’s enzymes—chemicals that your body naturally synthesizes during your sexual stimulation.

In rare cases, sildenafil can cause a serious drop in blood pressure, potentially leading to dizziness or fainting.

Finally, sildenafil should not be taken by pregnant or breastfeeding women as it can harm their unborn babies. It’s important to note, that not all patients with erectile dysfunction have adverse reactions to sildenafil.

It's important to do your research and do your homework before you start taking any new medications.

It's also important to talk to your doctor about your health, especially if you have underlying health conditions, including heart disease, high blood pressure, or kidney disease.

It's best to take all your medications exactly as directed, even if you start feeling better before you know it.

You can take Viagra, Cialis, Levitra, or Staxyn if you're under 18 years old, or over 60.

If you're taking medications for high blood pressure or diabetes, you can take a nitrate medication to lower your blood pressure. This can help lower your blood pressure by relaxing your blood vessels.

If you have pulmonary arterial hypertension (PAH), your doctor may recommend lowering your blood pressure by taking medications to treat the underlying disease.

If you have heart problems, including a recent heart attack or stroke, your doctor may recommend taking a beta blocker, such as Atorvastatin or Propranolol, or a diuretic, such as Diuretic Mist.

Talk to your doctor about all the medications you're currently taking, including over-the-counter medicines, vitamins, and herbal supplements.
