Cialis is a type of PDE5 inhibitor which works by increasing the blood flow to the penis after sexual stimulation. The blood vessels delivering blood to the penis increase the amount of blood they deliver, and the blood vessels carrying blood away from the penis decrease the removal of blood, helping the user to achieve and sustain an erection.

The recommended starting Cialis dosage is 10mg, and you can increase it to 20mg if you find the response to be inadequate. The tablets should be swallowed with water approximately 30 minutes before sexual activity, but this amount of Cialis should not be used on a continuous daily basis.

Unlike its competitors, Cialis has two different treatment approaches. It may be taken on an as-needed basis, or it may be taken daily at a lower dosage. The Cialis tablets that are designed to be taken daily come in a 2.5mg dosage and a 5mg dosage.

PostMyMeds offer Cialis in both 10mg and 20mg tablets

If you were prescribed the 5mg or 10mg dose and find that it doesn’t work for you, you might want to ask your doctor if you can take the higher dose. If that doesn’t work either, it’s possible that a different drug will be more effective for you. On our website we sell a range of products for erectile dysfunction such as Viagra, Levitra or Spedra.

You can buy Cialis online through our site and have it delivered straight to your door, and we have access to many other brands of erectile dysfunction medication that we haven’t listed if you’re used to a different product. Just leave us a message on our site and our dedicated team will get back to you.

How long does Cialis last?

Cialis tends to last between 24 and 36 hours. The fact that the effects are so long-lasting is one of the main reasons many men prefer it to other options on the market such as Viagra. People have different experiences with Cialis, but it’s not unusual to take it on a Friday night and still experience its effects on Sunday morning. The extended duration of Cialis’ effects allows for more spontaneity and less guesswork about when you should take it, which could have obvious benefits for your sex life!

Can I drink alcohol with Cialis?

In general, it is safe to drink a moderate amount of alcohol after you’ve taken Cialis, but drinking too much will increase your risk of side effects such as dizziness, headaches, increased heart rate and lower blood pressure.

This effect occurs because Cialis and alcohol are both vasodilators, i.e. substances that lower your blood pressure by relaxing the walls of your blood vessels. Orthostatic hypotension (the type of dizziness you might experience from standing up quickly) can be even more likely with Cialis than with some other erectile dysfunction drugs. This is probably because Cialis stays in your system longer than many other ED drugs.

How likely am I to experience side effects from using Cialis?

Cialis use does carry a small risk of side effects, but it is worth noting that only between 1% and 10% of users experience any of them at all. The most common side effects include:

  • Feeling nauseous or sick
  • Headaches
  • Blurred vision or eye pain
  • Difficulty breathing
  • Finding blood in your urine
  • A prolonged erection
  • Heightened heart rate
  • Changes to your blood pressure levels
  • Nosebleeds
  • Swollen hands, feet or ankles
  • Fatigue

You are more likely to experience side effects if you take more than the recommended Cialis dosage, or if you’re using it alongside recreational drugs, such as poppers or alcohol. Some prescription medications can also interact negatively with Cialis, so ask your doctor if you aren’t sure.

How long does it take for Cialis to leave your system?

Cialis has a long half-life, so it stays in your system longer than other erectile dysfunction drugs. Viagra has a half-life of 4 hours, while Cialis has a half-life of 17 hours. Your overall health and age can affect how well Cialis works for you, and how long it takes your body to process it. Diabetes, nervous system conditions such as multiple sclerosis and heart conditions like atherosclerosis (fat buildup in your blood vessels) can all make erectile dysfunction treatments like Cialis and Viagra less effective and less long lasting.
