Cialis

Cialis® is a prescription medicine that contains tadalafil, a drug in a group called phosphodiesterase type-5 (PDE5) inhibitors. It is used in adults to treat erectile dysfunction (ED) and the signs and symptoms of benign prostatic hyperplasia (BPH), or both together. Cialis® works with the body’s natural response to sexual stimulation and helps improve blood flow in certain tissues.

For ED, Cialis® may help men achieve and maintain an erection when they are sexually stimulated.

Cialis® is taken by mouth as a tablet and should only be used as prescribed by a healthcare provider. Depending on your condition and treatment plan, your provider may recommend taking Cialis® when needed before sexual activity or once daily at a lower dose.

Your provider will determine the right dosing schedule based on your health, other medications you take, and whether you are being treated for ED, BPH, or both. Cialis® can be taken with or without food.

• Taken orally as a tablet
• May be prescribed as needed or once daily, depending on the condition
• Your healthcare provider selects the dose based on your health profile
• Can be taken with or without meals
• Should be used exactly as prescribed

Like all prescription medicines, Cialis® can cause side effects. Many people tolerate it well, but some may experience mild or temporary symptoms. The most commonly reported side effects include headache, indigestion, back pain, muscle aches, flushing, nasal congestion, and pain in the arms or legs.

In rare cases, Cialis® may cause more serious reactions that require immediate medical attention. If you experience certain warning symptoms, you should stop taking the medication and seek medical help right away.

• Common side effects may include headache, flushing, or nasal congestion
• Some people report indigestion, back pain, or muscle aches
• These symptoms are usually mild and may improve over time
• Get urgent medical care if an erection lasts more than 4 hours
• Seek immediate help for sudden vision loss, hearing changes, or chest pain during sexual activity

Yes. Cialis® can generally be taken with or without food. Eating a meal does not prevent the medication from being absorbed, so many people take it at a time that fits their daily routine or treatment schedule.

However, it is still important to follow the instructions provided by your healthcare provider. They may recommend a specific schedule depending on whether the medication is prescribed as needed or once daily.

• Food does not typically change how Cialis® is absorbed
• The tablet should be swallowed whole with water
• Follow the dosing instructions provided by your provider
• Ask your pharmacist if you have questions about timing with meals

Drinking small amounts of alcohol may not affect everyone the same way, but combining alcohol with Cialis® can increase the chance of certain side effects, including dizziness, headache, or drops in blood pressure.

Because tadalafil can affect blood vessels, drinking large amounts of alcohol at the same time may increase the likelihood of symptoms such as lightheadedness or a rapid heartbeat.

• Alcohol may increase the risk of low blood pressure symptoms
• Large amounts of alcohol may worsen dizziness or flushing
• Individual tolerance can vary from person to person
• Speak with your provider if you regularly drink alcohol

If you feel faint, dizzy, or unwell after drinking alcohol with Cialis®, contact a healthcare professional. For more safety details, see the Important Safety Information.

What to do depends on how the medication was prescribed. If you take Cialis® once daily, take the missed dose when you remember unless it is close to the time for your next scheduled dose.

If Cialis® was prescribed as needed, it is typically taken before sexual activity rather than on a fixed schedule, so a missed dose may simply mean waiting until the next planned use.

• Do not take two doses at the same time
• Resume your normal dosing schedule if a daily dose is missed
• Follow the instructions given by your healthcare provider
• Ask your pharmacist if you are unsure what to do

If you miss doses frequently or have questions about your dosing plan, your provider can help clarify the best approach.

Cialis® may be prescribed in two different ways, depending on the condition being treated and your healthcare provider’s recommendation. Some people take the medication as needed before sexual activity, while others may be prescribed a lower daily dose.

Your provider will decide which schedule is appropriate after reviewing your symptoms, health history, and other medications you take.

• Some treatment plans use as-needed dosing
• Other treatment plans use once-daily dosing
• Your provider determines the most appropriate schedule
• Do not change how often you take the medication on your own

If your current dosing schedule does not seem to be working well for you, discuss it with your healthcare provider rather than adjusting the medication yourself.

No. You should not adjust your dose without speaking to your healthcare provider first. The correct dose depends on several factors, including your health history, other medications, and whether the medicine is prescribed daily or as needed.

Changing the dose on your own could increase the risk of side effects or interactions with other medications.

• Dose adjustments should always be made by a healthcare provider
• Your provider may review your medical history and medications
• They may recommend a different dose or treatment approach
• Never take more tablets than prescribed

If Cialis® is prescribed as needed, it is generally taken before sexual activity according to your provider’s instructions. The medication works together with the body’s natural response to sexual stimulation.

Because individual responses can vary, your healthcare provider may discuss timing and expectations with you when prescribing the medication.

• Take the tablet as directed by your healthcare provider
• Sexual stimulation is still required for an erection
• Follow the dosing instructions on your prescription
• Avoid taking more than the prescribed amount

If you are unsure about the best timing or have questions about your treatment plan, your provider or pharmacist can help explain how to use the medication safely.

es. Cialis® helps support the body’s natural response to sexual stimulation, but it does not automatically cause an erection on its own.

The medication works through a biological pathway that is activated during sexual arousal. Without stimulation, the medication generally does not produce the intended effect.

• Sexual stimulation is required for erectile response
• The medication does not increase sexual desire
• Results may vary from person to person
• Your provider can discuss realistic expectations

If you have ongoing concerns about sexual performance or if the medication does not seem to help, your healthcare provider may recommend additional evaluation.

Using Cialis® together with other medicines used to treat erectile dysfunction is generally not recommended unless a healthcare provider specifically advises it. Combining treatments that affect the same biological pathway may increase the risk of side effects.

Before using any additional ED medication or treatment, consult your provider so they can determine whether it is safe.

• Tell your provider about all ED medications or supplements
• Do not combine treatments without medical guidance
• Combining therapies may increase side-effect risk
• Your provider can recommend safe alternatives if needed

If you are considering new treatments or supplements, discuss them with your provider before taking them.

Grapefruit and grapefruit juice can affect how certain medications are processed in the body. In some cases, grapefruit may change the way tadalafil is metabolized, which could increase the amount of medicine in your system.

Because of this possibility, it is important to speak with your healthcare provider if grapefruit is a regular part of your diet.

• Grapefruit may influence how the body processes some medications
• It could potentially increase medication levels in the body
• Individual risk can vary depending on your treatment plan
• Your provider can advise whether dietary adjustments are needed

Cialis® should be stored at room temperature in its original container, away from excessive moisture and heat. Keeping medications stored properly helps maintain their stability and effectiveness.

If your medication has passed the expiration date listed on the packaging, consult your pharmacist before taking it.

• Store at normal room temperature
• Keep tablets in the original container
• Protect the medication from moisture and heat
• Keep out of reach of children and pets

Yes. Cialis® is a prescription medication, which means a licensed healthcare provider must review your medical history before it can be prescribed.
