Indications and Usage of Cialis
Cialis treats erectile dysfunction (ED), helping men achieve and maintain an erection sufficient for satisfactory sexual intercourse. It’s prescribed for adult men with ED of various etiologies.
Cialis also manages the symptoms of benign prostatic hyperplasia (BPH), reducing urinary symptoms like frequent urination, weak urine stream, and nighttime urination. This dual action makes it a suitable choice for men experiencing both ED and BPH.
The recommended starting dose for ED is 10 mg, taken as needed, at least 30 minutes before sexual activity. For BPH, the usual dose is 5 mg once daily. Your doctor will determine the appropriate dose based on your individual needs and health status.
Cialis is not suitable for everyone. Men with certain heart conditions, low blood pressure, or those taking specific medications should discuss its use with their doctor before starting treatment. Additionally, it’s vital to inform your doctor about any other health problems or medications you are using.
Remember, Cialis is a prescription medication. Always follow your doctor’s instructions for use and dosage. Never share your medication with others.
Dosage and Administration Guidelines
Cialis is available in 2.5 mg, 5 mg, 10 mg, and 20 mg tablets. The recommended starting dose is 10 mg, taken as needed, at least 30 minutes before sexual activity.
For some men, a lower dose of 2.5 mg or 5 mg may be sufficient. Conversely, those who don’t achieve satisfactory results may find a higher dose of 20 mg beneficial. Your doctor will help determine the best dosage for you, considering your individual health needs and response to treatment.
Take Cialis only as directed by your doctor. Do not exceed the recommended dosage. Cialis should be taken only when sexual activity is anticipated. Daily use should only be considered under your doctor’s guidance.
The effect of Cialis can last up to 36 hours. Do not take more than one tablet in a 24-hour period. Avoid grapefruit or grapefruit juice while taking Cialis, as it can affect how your body processes the medication.

This information is not exhaustive. Always consult your physician or pharmacist for complete information and guidance before starting or continuing Cialis therapy.
Adverse Reactions and Side Effects
Cialis, like all medications, can cause side effects. The most common are headache, flushing, nasal congestion, and indigestion. These usually are mild and temporary.
More serious, though less frequent, side effects include changes in vision, such as blurred vision or temporary blue-tint vision. If you experience sudden vision loss, stop taking Cialis and seek immediate medical attention. This is a serious potential side effect requiring prompt medical care.
Back pain and muscle aches are also possible. These side effects generally resolve on their own. However, persistent or severe pain warrants contacting your doctor.
Prolonged erection (priapism) is a rare but serious side effect. It requires immediate medical attention to prevent permanent damage. Seek medical help immediately if an erection lasts longer than four hours.
Hearing loss, including sudden deafness, is another potential side effect, although infrequent. Contact your doctor immediately if you experience any hearing changes while taking Cialis.
Allergic reactions, such as rash, itching, or swelling, are possible. Discontinue use and contact your doctor if you have an allergic reaction.

Drug Interactions with Cialis
Always inform your doctor about all medications you’re taking, including over-the-counter drugs, vitamins, and herbal supplements, before starting Cialis. Some medications can significantly affect Cialis’s effectiveness or increase the risk of side effects.
Here’s a summary of key interactions:
- Nitrates: Combining Cialis with nitrates (found in some heart medications) can cause a dangerous drop in blood pressure. This combination is strictly contraindicated.
- Alpha-blockers: These medications, often used to treat high blood pressure or enlarged prostate, can increase the risk of low blood pressure when taken with Cialis. Your doctor might adjust your dosage or recommend alternatives.
- CYP3A4 inhibitors: These medications (like ketoconazole and ritonavir) can increase Cialis levels in your blood, potentially intensifying its effects and side effects. Your doctor may need to lower your Cialis dose.
- CYP3A4 inducers: These medications (like rifampin and carbamazepine) can decrease Cialis levels, reducing its effectiveness. Your doctor may need to adjust your dosage accordingly.
- Alcohol: While moderate alcohol consumption usually doesn’t pose a significant problem, excessive alcohol intake can worsen Cialis’s side effects, especially dizziness and headaches.
Specific interactions can vary depending on the individual medication, dosage, and your overall health. It’s crucial to have an open discussion with your physician about all your medications and health conditions to ensure safe and effective use of Cialis.

Overdosage and Management
If an overdose is suspected, immediately contact a poison control center or seek medical attention. Symptoms of overdose may include headache, flushing, nasal congestion, visual disturbances, and hearing loss. These are usually mild and transient.
There is no specific antidote for Cialis overdose. Treatment focuses on supportive care. Monitor vital signs and provide symptomatic treatment as needed. Hemodialysis is unlikely to be of benefit because tadalafil is highly protein-bound and extensively metabolized.
For management of adverse effects, consider discontinuing Cialis. If hypotension occurs, supportive measures such as intravenous fluids may be necessary. For severe hypotension, appropriate vasopressor support should be initiated.
Close observation of the patient is recommended following a suspected overdose, especially if other medications are involved. Consult relevant medical guidelines for further assistance in managing potential complications.
Pharmacokinetics and Pharmacodynamics of Tadalafil
Tadalafil absorption is rapid after oral administration, reaching maximum plasma concentrations (Cmax) within 2 hours. Food modestly delays absorption, increasing Cmax and slightly extending time to Cmax. Therefore, tadalafil can be taken with or without food.
Tadalafil is extensively metabolized by the liver, primarily via CYP3A4. A small portion undergoes glucuronidation. The elimination half-life is approximately 17.5 hours. This long half-life allows for once-daily dosing.
Tadalafil’s pharmacodynamic effects stem from its selective inhibition of phosphodiesterase type 5 (PDE5) in the corpus cavernosum. This inhibition increases cGMP levels, leading to smooth muscle relaxation and improved blood flow to the penis, facilitating penile erection.
Steady-state plasma concentrations are achieved within 5 days of daily dosing. The pharmacokinetic profile supports once-daily administration for the treatment of erectile dysfunction and benign prostatic hyperplasia.
Renal impairment reduces tadalafil clearance, leading to increased exposure. Dosage adjustments are recommended for patients with severe renal impairment. Hepatic impairment also impacts clearance; adjustments may be necessary based on the severity of liver disease.
Tadalafil’s interaction with other medications should be carefully considered. Coadministration with strong CYP3A4 inhibitors, such as ketoconazole and ritonavir, significantly increases tadalafil concentrations. Conversely, inducers of CYP3A4, such as rifampicin, may decrease tadalafil concentrations.
Individual patient factors, including age, concomitant medications, and underlying health conditions, influence tadalafil pharmacokinetics and pharmacodynamics. A physician’s assessment is crucial for appropriate dosage selection and monitoring.
