What is Cardiax 20 mg?
Cardiax 20 mg is a medicine with a low dosage that contains sildenafil citrate, which is the exact active ingredient that is found in conventional erectile dysfunction (ED) drugs. In contrast to higher dose options such as 50 mg and 100 mg tablets, the 20 mg dosage is designed specifically for men who require a less sluggish, easier to manage dose–particularly those who have sensitivity to drugs or need daily treatment under medical supervision.
The dose can also be given off-label to patients suffering from mild ED or the treatment of pulmonary arterial hypertension (PAH), depending upon the recommendation of a doctor.
How It Works
The Role of PDE5 Inhibition
Cardiax 20 mg acts by blocking phosphodiesterase type five (PDE5), an enzyme that regulates the flow of blood within the penis. Through blocking this enzyme, sildenafil boosts levels of cyclic GMP that relax muscles and smooth blood vessels, allowing for increased blood flow in sexual stimulation.
What to Expect
- Onset: The typical work day begins in 30 to 60 minutes
- Peak effect: In the range of 1 to 2 hours
- Duration: It can take up to 4 to 5 hours
The erection doesn’t occur in a non-arousal way, but it does allow the body to react more effectively when stimulation happens.
Who Might Benefit from Cardiax 20 mg?
This dose is especially suitable for:
- Males with mild erectile dysfunction
- People are trying sildenafil citrate first time
- People who are seeking the possibility of a regular or moderate dosage
- Patients taking it under the supervision of a medical professional for PAH
This is a great option if you want to stay clear of the more severe adverse effects that are often associated with 100 or 50 mg formulas.
How to Take It Safely
Proper Use Guidelines
- Consume just one tablet in water. Drink it 30 to 60 minutes before sexual activity.
- Take care not to exceed one tablet during 24 hours.
- Beware of taking a drink after the consumption of a large or high-fat food–this may delay the start of the disease.
- Avoid mixing with or drinking, or the use of recreational substances
Important Interactions
Avoid using if you:
- Use Nitrate-based medications
- Are you taking medications to lower blood pressure, such as Alpha-blockers
- If you have serious liver, heart, or kidney issues.
- Are you taking any different ED medicines for treating ED
Make sure you talk to your GP when you’re taking medication to treat hypertension, heart disease, or prostate problems.
Possible Side Effects
Though most patients can tolerate the dose of 20 mg very well, adverse reactions can happen:
Mild:
- Nasal congestion
- Indigestion
- Lightheadedness
- Headache
- Facial flushing
Rare but serious:
- Shortness of breath
- Prolonged erection lasting over 4 hours (priapism)
- Sudden vision or hearing loss
- Chest pain
Contact a doctor immediately if you have an allergic reaction that is serious.
