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.
Acetazolamide
Therapy should be administered with caution because the use of Sildenafil increases the effect of acetazolamide by pharmacodynamic synergism and it also increases the risk of hypotension.
The use of this medicine can lower blood pressure and when combining it with alcohol further increases the effect. 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.

No. People do it, but getting it through Customs without it being confiscated depends on which agent interviews you upon arrival back in the US.
The Food and Drug Administration policy on theimportation of prescription drugspurchased abroad is fairly clear.
Under most circumstances,federal guidelines prohibit the importation of such drugs for personal use, largely because medications sold in another country have not been approved by the FDA for use in this country.
That said, your personal experience in returning to the United States with or another prescription drug you’ve purchased abroad depends to a very large extent on the Customs agent who checks your baggage upon your return.
If you’ve been honest in filling out your Customs declaration and have listed the foreign-bought medications, Customs legally could seize the drugs. However, the tendency is to look the other way if the drug in question is not a controlled substance and if the amount purchased doesn’t exceed a 90-day supply.
do allow thepersonal importation of prescription drugs that treat serious medical conditionsand that aren’t available in the United States.
However, there are a few other conditions that govern the policy on such drugs.
The FDA’s guidelines apply toprescription medications that are brought in from any country outside the United States, including Canada.
While most over-the-counter medications can be imported in amounts consistent with personal use, this policy does not extend to products that are OTC in other countries but available only by prescription in the United States.
The bottom line: Be aware that you’re running arisk of confiscation when you return to the United States with prescription drugsbought abroad.

The active ingredient in the drug sildenafil is not the same as the chemical name sildenafil citrate, the FDA said.
However, the drug, sold under the brand name Viagra, does not contain the chemical name sildenafil citrate, the agency said.
The warning, however, is specific to sildenafil. It does not mean that it is safe for human use. A small number of patients who take the drug are at risk of a serious, sometimes fatal, reaction called priapism.
The FDA also said that sildenafil is not approved by the FDA to treat pulmonary hypertension. The drug, sold under the brand name Viagra, is intended to treat erectile dysfunction.
It's important to remember that sildenafil should not be used in patients who have heart problems. If sildenafil causes a serious side effect, it is dangerous.
The only treatment for erectile dysfunction in men is a prescription-strength, 50-milligram tablet taken only once a day.
The only treatment for pulmonary hypertension, according to the FDA, is a 50-milligram tablet taken only once a day.
The agency also says that sildenafil has been found to have adverse effects in patients who are not taking nitrates.
A study published in the International Journal of Cardiology in July found that about 30 per cent of the male patients taking the drug had serious, sometimes fatal, side effects, including an increased risk of priapism, a heart attack and a stroke.
It's unclear how the warning against sildenafil applies to patients taking nitrates or other drugs for angina, heart failure, high blood pressure or kidney disease.
Dr Tom Hasty, a urology consultant, said: "A small number of patients who take the drug are at risk of a serious, sometimes fatal, reaction called priapism, a heart attack or a stroke".
In rare cases, priapism may happen within minutes of taking a dose of sildenafil.
The warning is based on a case series from the European Medicines Agency and published last year in the British Medical Journal. In that case, the drug was tested for safety.
"The warning is a warning to avoid the use of sildenafil in patients with cardiovascular disease," Dr Hasty added. "Patients should be instructed to discuss the risks of sildenafil with their doctor."
A drug to treat erectile dysfunctionIn the European Union, the European Medicines Agency says that there is no evidence that Viagra and other ED drugs increase the risk of priapism. In the U. S., Viagra and similar drugs are available for patients only.
The FDA said that the risk of priapism is very low in men who take nitrates. "This does not mean that Viagra or similar drugs do not increase the risk of priapism," it said. "Viagra does not increase the risk of priapism."
"The FDA has not determined whether Viagra and similar drugs should be used together," the FDA said.
A study published in the British Medical Journal in June found that about one in 10 men who used nitrates for angina had a serious reaction to the drug. The reaction may occur because nitrates are not a good choice in patients who do not respond to the drug. In this case, the reaction may occur because of the risk of priapism.
The drug has not been linked to an increased risk of death in patients taking nitrates for heart failure.
"In patients who are at risk of having an angina attack, heart failure or other heart problems, the risk of developing priapism increases as the number of patients increases," the FDA said.
