Cialis 5 mg

Cialis 5 mg is a prescription medication containing tadalafil, a phosphodiesterase type 5 (PDE5) inhibitor. It is used primarily to treat erectile dysfunction (ED) and, in appropriate patients, symptoms associated with benign prostatic hyperplasia (BPH).

Tadalafil works by increasing blood flow to certain tissues in the body. For erectile dysfunction, sexual stimulation is still required for the medication to produce an erection.

For authoritative patient information, see the U.S. National Library of Medicine's MedlinePlus information on tadalafil.

What Is Cialis 5 mg Used For?

Cialis 5 mg may be prescribed for:

• Erectile dysfunction (ED)

• Symptoms of benign prostatic hyperplasia (BPH)

• Erectile dysfunction occurring together with BPH

For ED, tadalafil helps improve the ability to obtain and maintain an erection when a person is sexually stimulated.

For BPH, tadalafil can help relieve urinary symptoms such as difficulty beginning urination, weak urine flow, frequent urination, and the need to urinate urgently.

How Does Tadalafil Work?

Tadalafil blocks the PDE5 enzyme. This allows certain blood vessels to relax and increases blood flow.

During sexual stimulation, nitric oxide signaling causes the release of substances that relax smooth muscle in the penis. PDE5 normally breaks down one of these signaling molecules. By inhibiting PDE5, tadalafil helps maintain the blood flow necessary for an erection.

Tadalafil does not automatically produce an erection without sexual stimulation.

Cialis 5 mg and Daily Treatment

A 5 mg tadalafil tablet may be prescribed as a once-daily treatment for certain patients with erectile dysfunction or BPH.

Daily tadalafil should be taken exactly as directed by the prescribing healthcare professional. The appropriate regimen depends on the individual's health, other medications, kidney and liver function, and the condition being treated.

Patients should not change the prescribed dose without consulting their healthcare professional.

Duration of Action

Tadalafil has a relatively long duration of action compared with some other PDE5 inhibitors. This characteristic allows certain prescribed tadalafil regimens to provide treatment coverage over an extended period.

The medication's duration can vary between individuals and may be affected by other medicines and health conditions.

Common Side Effects

Possible side effects of tadalafil include:

• Headache

• Indigestion

• Back pain

• Muscle aches

• Flushing

• Nasal congestion

• Pain in the limbs

These effects are often mild, but patients should contact a healthcare professional if symptoms are severe, persistent, or concerning.

Important Safety Information

Cialis can cause a drop in blood pressure, particularly when combined with certain other medications.

Nitrates

Cialis must not be taken with nitrate medications such as nitroglycerin because the combination can cause a dangerous and potentially life-threatening reduction in blood pressure.

People who use nitrate medicines for chest pain should tell their healthcare professional before taking tadalafil.

Alpha-Blockers and Blood-Pressure Medicines

Tadalafil may interact with alpha-blockers and certain blood-pressure medications, potentially causing additional blood-pressure reduction.

Patients should provide their doctor or pharmacist with a complete list of their medications.

Cialis and Alcohol

Large amounts of alcohol can increase the risk of dizziness, rapid heartbeat, and low blood pressure when taking tadalafil.

Patients should discuss alcohol consumption with their healthcare professional, particularly if they take blood-pressure medications or have cardiovascular conditions.

Serious Adverse Effects

Patients should seek immediate medical attention for certain uncommon but serious reactions.

Prolonged Erection

An erection lasting more than four hours requires emergency medical attention. A prolonged erection can damage penile tissue and result in permanent erectile dysfunction if untreated.

Sudden Vision Changes

Rare cases of sudden vision loss have been reported with PDE5 inhibitors. Any sudden change or loss of vision should be treated as a medical emergency.

Sudden Hearing Changes

Sudden hearing loss or significant changes in hearing require prompt medical evaluation.

Cardiovascular Considerations

Sexual activity places additional demands on the cardiovascular system. Patients with heart disease, recent cardiovascular events, uncontrolled blood pressure, or other significant cardiovascular conditions should discuss sexual activity and tadalafil treatment with their healthcare professional.

The FDA Cialis prescribing information provides detailed prescribing and safety information.

Drug Interactions

Before taking tadalafil, patients should tell their healthcare professional about all prescription medicines, over-the-counter medicines, vitamins, and supplements they use.

Important interactions may involve:

• Nitrate medicines

• Alpha-blockers

• Certain blood-pressure medicines

• Other PDE5 inhibitors

• Some antifungal medicines

• Certain antibiotics

• HIV medicines

• Other medications that affect tadalafil metabolism

Patients should not combine Cialis with another erectile-dysfunction medication unless specifically instructed by their healthcare professional.
