Overview Of The Interactions

While trying to give an overview about the interactions of Sildenafil, the same needs to be divided into some essential parts, viz. –

  • Drug Interactions – the drugs with which generic Viagra interacts to form complications.
  • Food Interactions – the foods that Sildenafil interacts with and forms complicated issues before you.

This is why we have divided our article into these two halves for you. Here are the common interactions that we will be discussing in detail throughout the article –

Drug Interactions

  • All types of Nitrates, including Nitrostat and Monoket
  • Riociguat or sGC stimulators
  • α-Blockers
  • Blood thinners

Food Interactions

  • Grape juice
  • Alcohol
  • High-fat meals

With this overview, let us go for an elaborate and complete understanding of the interactions.

➤ Detailed Understanding Of The Drug Interactions

  • Each and every drug has some chemical composition. Like the way you know that different chemical substances react with each other to form some elements that are not always positive, the same happens with the drugs.
  • In case of a purple Viagra pill Australia, there are some drugs that either reduce the effect of Sildenafil or increase the effect. At times, the combination of both drugs shows some adverse effects on the body. With that basic understanding, let us get deeper into the interactions.

➦ Interaction With Nitrates

  • Nitrates are often used to widen the blood vessels in your body, and especially the heart. While widening the blood vessels, they often work on the blood pressure and reduce it.
  • When you take a red Viagra pill Australia, the same too works on your blood pressure and reduces the pressure. Thus, when both the drug-types work together on your blood pressure, pressure can fall to a fatal level.
  • Viagra flavoured 100 mg Australia often works on the blood pressure to reduce pressure and make it easier for your heart to transmit blood to the penis for a harder erection. And the combination of nitrate enables a bad fall in BP, which can be fatal at times.

➦ Interaction With Α-Blockers

  • Doxazosin, like α-Blockers, work on the irregular prostate. They even work on High BP, similar to Nitrates. It is necessary to rework the BP, as otherwise the prostate irregularity cannot be removed.
  • Naturally, when you take Blue pill Sildenafil with α-Blockers, they will react in the same way as that of nitrates. Therefore, there is a need of doing alterations to the dosage of both female Viagra Australia and α-Blockers. Do not try to fix that on your own. Get to your doctor, he will do the needful.

➦ Blood Thinner And Other Blood Pressure Medications

  • Blood thinners are often the recommendation when you are running with an extensive sugar level, or you have undergone a bypass and applied a stent in your heart. Blood pressure medications work directly on the blood pressure. Examples of such are losartan or amlodipine.
  • The interaction of sildenafil with the drugs is somewhat similar to that with nitrates, where the BP level falls sharply. Hence, if you are taking such medications regularly, you need to consult your doctor. He will do something or other to adjust the dose of Cenforce 200, so that you never have to face any fatal condition.

➦ Riociguat Or Similar Sgc Stimulators

  • Riociguat or any type of sGC stimulator, if combined with sildenafil oral powder, can dangerously affect your blood pressure. If not taken care of from the beginning, chances are very high that the fall of BP will be really fatal for you.
  • Hence, if you take such sGC stimulators and your doctor is prescribing you Generic Viagra, immediately tell him about your earlier medication. He will either adjust the dosage or will recommend you some alternatives.

➤ Food Interactions With Sildenafil

Talking about interactions of sildenafil, you cannot overlook the interaction of the same with foods. The interaction of a drug is not confined to other drugs. Interaction with food is also an integral part of the same and hence must be detailed before you. Otherwise, talking about the interactions will remain incomplete. Hence, here are the major food interactions you can face while taking Generic Viagra.

➦ High-Fat Meals

If you take sildenafil from Australiarxmeds with high-fat meals, the effectivity of the drug will reduce. High-fat meals take more time to dissolve in the blood, and hence, lowering the blood pressure with Viagra will face challenges. Therefore, never have high-fat meals with Sildenafil. Even if you are looking to go for intercourse without medication, then too, avoid high-fat meals.

➦ Grape Juices

A study shows that grape juice blocks the enzyme of the liver called CYP3A4. This enzyme, when blocked, can break the Sildenafil and stop it from working effectively. Hence, never have grape juice while taking Viagra.

➦ Alcohol

Alcohol combined with sildenafil triggers dizziness, and blood pressure is also affected. Hence, it is a strict guide to restrict consuming alcohol with Sildenafil or any PDE5 inhibitor.
