Is 40 mg of Cialis too much?

4 min read

Taking a higher-than-prescribed dose, such as 40 mg of Cialis, significantly increases the risk of serious and dangerous side effects and provides no additional benefit for treating ED. The maximum recommended daily dose of Cialis for erectile dysfunction is lower than 40mg.

Quick Summary

Taking 40 mg of Cialis is not recommended for erectile dysfunction and substantially increases the risk of serious side effects like dangerously low blood pressure. The maximum safe dose for ED is lower than 40mg.

Key Points

  • Dosage Exceeds Recommendations: The maximum recommended dose of Cialis for erectile dysfunction is significantly lower than 40 mg, making 40 mg a dangerous amount for that purpose.

  • Increased Risk of Side Effects: Taking 40 mg of Cialis significantly increases the risk and severity of side effects, including headaches, flushing, and muscle pain, without improving efficacy.

  • Cardiovascular Dangers: A high dose can cause a severe drop in blood pressure, which may lead to dizziness, fainting, or more serious cardiovascular events, especially in those with pre-existing heart conditions.

  • Different Medical Use: The 40 mg dose of tadalafil is specifically for a separate condition, pulmonary arterial hypertension (PAH), under the brand name Adcirca and requires strict medical supervision.

  • Consult a Doctor for Adjustments: If your current dose is ineffective, consult your healthcare provider to adjust the dose, switch medication, or explore other treatment options rather than self-medicating with a higher dosage.

  • Priapism Risk: Exceeding the recommended dosage can increase the risk of priapism, a prolonged, painful erection that requires immediate medical attention to prevent permanent damage.

The Standard Cialis Dosages

Cialis (tadalafil) is a prescription medication available in several strengths to provide flexibility based on the individual's needs and tolerability. The dosing strategy for erectile dysfunction (ED) typically falls into one of two categories: as-needed or daily use. In both cases, the dosage is determined and adjusted by a healthcare provider, not by the patient.

As-Needed Cialis

For men who do not have sexual activity frequently, the 'as-needed' dosing is a common choice. A doctor can adjust the dose based on effectiveness and side effects. The effects of an as-needed dose can last for up to 36 hours, but you should never take more than one dose per day.

Daily Cialis

For men who have more frequent sexual activity, a low-dose daily regimen helps maintain a consistent level of medication in the body, allowing for more spontaneous intimacy. A doctor can adjust the dose if the initial dose is not effective enough. This approach provides continuous support and is also used to treat benign prostatic hyperplasia (BPH) symptoms.

Why 40 mg of Cialis is Dangerous for ED

Regardless of the dosing method, the maximum recommended daily dose of Cialis for erectile dysfunction is significantly lower than 40 mg. Taking 40 mg for ED is a dangerous and medically unsupervised action that offers no additional benefit in terms of efficacy but substantially increases the risk of severe adverse effects.

  • Increased Side Effect Risk: Side effects from tadalafil are often dose-dependent, meaning they become more frequent and severe at higher concentrations. Taking a dose significantly higher than the maximum recommended for ED can intensify common side effects like headaches, flushing, muscle aches, and indigestion.
  • Dangerously Low Blood Pressure: Cialis works by relaxing smooth muscles in blood vessels, which lowers blood pressure. Taking a 40 mg dose can cause a dangerous and sudden drop in blood pressure (hypotension), leading to symptoms like dizziness, lightheadedness, and fainting.
  • Priapism: A serious and rare side effect is priapism, a painful erection lasting more than four hours. Higher doses of Cialis increase this risk, and untreated priapism can cause permanent damage to the penis.
  • Cardiovascular Events: In some cases, overdose has been linked to severe cardiovascular complications, including heart attack or stroke, particularly in individuals with pre-existing heart conditions.
  • Vision and Hearing Changes: Higher doses have been associated with a greater risk of vision problems, including sudden vision loss, and hearing issues, such as ringing in the ears or sudden hearing loss.

Cialis vs. Adcirca: A Crucial Distinction

It is important to clarify that while the active ingredient tadalafil is used in a 40 mg dose, it is not for the treatment of ED.

Adcirca is another brand name for tadalafil, prescribed specifically for pulmonary arterial hypertension (PAH), a type of high blood pressure affecting the arteries in the lungs. A 40 mg daily dose may be used for this condition, but it is taken under very strict and careful medical supervision. Taking 40 mg of Cialis for ED is a completely different, and unsafe, application of the drug.

Comparison of Cialis Dosages for ED

Feature As-Needed Dosage Daily Dosage
Maximum Dose (per day) Lower than 40 mg Lower than 40 mg
Flexibility Provides a 36-hour window for sexual activity. Allows for spontaneous sexual activity anytime.
Primary Purpose For men with infrequent sexual activity. For men with frequent sexual activity or those treating both ED and BPH.
Side Effect Risk Higher dose carries a greater potential for side effects. Lower dose minimizes side effect risk.

What to Do If Your Current Dose Isn't Working

If you find that your prescribed dose of Cialis is not providing the desired effect, it is critical that you do not increase the dose yourself. The correct and safe course of action is to speak with your healthcare provider. They may suggest several alternatives:

  • Dosage Adjustment: Your doctor can assess your response and health to determine if a dosage adjustment within the safe limits is appropriate.
  • Alternative Treatments: If Cialis is ineffective, a doctor may recommend trying a different PDE5 inhibitor, like sildenafil (Viagra), or exploring other treatment options.
  • Lifestyle Changes: Discussing lifestyle factors like diet, exercise, and stress levels is important, as these can also affect erectile function.
  • Addressing Underlying Issues: ED can be a symptom of an underlying condition. A healthcare provider can investigate potential causes, such as psychological factors or other health problems.

Conclusion

Taking 40 mg of Cialis for erectile dysfunction is a significantly higher dose than recommended and poses serious health risks without providing any additional benefits for ED treatment. The maximum approved dose for ED is significantly lower than 40 mg, and exceeding this increases the likelihood of dangerous side effects, including severe hypotension and priapism. While a 40 mg dose of the active ingredient tadalafil is used for pulmonary arterial hypertension under the brand name Adcirca, this is a different medical context entirely. Always follow your doctor's prescribed dosage and consult them before making any changes. This is the safest and most effective way to manage erectile dysfunction.
