Why is this medication prescribed?

Cialis, or generic Tadalafil, is primarily prescribed for the treatment of erectile dysfunction (ED) in men. It belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors, which work by increasing blood flow to the penis during sexual stimulation. This helps men achieve and maintain an erection sufficient for sexual activity.

How should this medicine be used?

Here’s how Cialis should be used:

• Dosage: The typical starting dose is 10 mg taken before anticipated sexual activity. Depending on how well it works and whether there are any side effects, your doctor may adjust the dose to 20 mg or reduce it to 5 mg.
• Timing: Cialis is usually taken when needed, about 30 minutes to 1 hour before sexual activity. It can remain effective for up to 36 hours after taking the tablet, which is why it’s sometimes called the “weekend pill.”
• Administration: The tablet should be swallowed whole with a full glass of water. It can be taken with or without food, but heavy meals or meals high in fat may delay the onset of action.
• Frequency: Do not take more than one dose in a 24-hour period. If you anticipate regular sexual activity, your doctor might recommend a lower daily dose of 2.5 mg or 5 mg.
• Safety: It’s important to follow your doctor’s instructions precisely. Do not take Cialis more often than prescribed, and do not exceed the recommended dosage.
• Effectiveness: Cialis works only with sexual stimulation and does not increase sexual desire. It helps achieve an erection when there is sexual arousal.
• Interactions: Inform your doctor about all medications you are currently taking, including prescription drugs, over-the-counter medicines, and supplements, as some medications can interact with Cialis.
• Side effects: Common side effects include headache, indigestion, back pain, muscle aches, flushing, and stuffy or runny nose. Serious side effects are rare but can include sudden vision loss or decreased vision in one or both eyes, sudden hearing loss or ringing in the ears, and an erection that persists longer than 4 hours (priapism).

Other uses for this medicine

• Benign Prostatic Hyperplasia (BPH): Cialis is approved for the treatment of symptoms of BPH, which is an enlarged prostate gland. It helps to relax the smooth muscles in the prostate and bladder, improving urinary symptoms such as difficulty urinating, urgency, and frequency.
• Pulmonary Arterial Hypertension (PAH): Cialis is sometimes used off-label to treat PAH, a condition characterized by high blood pressure in the arteries of the lungs. It works by relaxing the blood vessels in the lungs to allow blood to flow more easily.

What special precautions should I follow?

Special Precautions for Cialis:

• Heart Conditions: Cialis can cause a sudden drop in blood pressure if taken with medications called nitrates, which are often prescribed for chest pain (angina). It is important to inform your doctor if you have any heart conditions or take medications for heart problems.
• Vision Problems: In rare cases, Cialis and similar medications have been associated with vision changes such as blurred vision, sudden decrease or loss of vision in one or both eyes. Seek immediate medical attention if you experience sudden vision loss.
• Priapism: This is a rare but serious side effect where an erection lasts for more than four hours. It requires immediate medical attention to prevent permanent damage to the penis.
• Drug Interactions: Cialis can interact with certain medications, including nitrates, alpha-blockers, antihypertensives, and drugs that affect the liver enzymes responsible for metabolizing Cialis. Always inform your doctor about all medications you are taking, including over-the-counter and herbal supplements.
• Allergies: Inform your doctor if you have any allergies to tadalafil or any other medications.
• Pregnancy and Breastfeeding: Cialis is not indicated for use in women. It is classified as Pregnancy Category B, which means it is generally considered safe to use during pregnancy but should only be used if clearly needed and under the supervision of a healthcare provider.
• Underlying Medical Conditions: It is important to disclose all your medical conditions to your doctor before starting Cialis, especially if you have liver or kidney problems, history of stroke or heart attack, or if you have been advised to avoid sexual activity due to health reasons.

Always follow your doctor’s instructions and read the patient information leaflet provided with your medication for detailed precautions and potential side effects specific to your situation.

What special dietary instructions should I follow?

There are no specific dietary restrictions associated with the use of Cialis. However, maintaining a healthy diet and avoiding excessive alcohol consumption may help optimize sexual function and overall health.

What should I do if I forget a dose?

If you forget to take a dose of Cialis, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.

What side effects can this medication cause?

Cialis (tadalafil) is generally well-tolerated by most people, but like any medication, it can cause side effects. The most common side effects of Cialis include:

• Headache: This is the most commonly reported side effect.
• Facial flushing: A sensation of warmth in the face, neck, or chest.
• Indigestion: Also known as dyspepsia, which can include symptoms like stomach discomfort, bloating, or nausea.
• Back pain: Muscle pain or discomfort in the lower back.
• Muscle aches: Typically affecting the arms and legs.
• Nasal congestion: Stuffy or runny nose.
• Dizziness: Feeling lightheaded or dizzy.
• Vision changes: Including blurred vision, changes in color vision, or difficulty distinguishing between blue and green colors.
• Rare side effects: These can include priapism (a prolonged erection lasting more than four hours), sudden decrease or loss of vision or hearing, and allergic reactions such as rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, or trouble breathing.

It’s important to note that not everyone experiences these side effects, and some may experience none at all. If you experience any severe or persistent side effects while taking Cialis, it’s essential to contact your healthcare provider promptly. Additionally, if you have any concerns about side effects or medication interactions, discussing them with your doctor or pharmacist can provide you with tailored advice and peace of mind.

What should I know about storage and disposal of this medication?

In case of emergency/overdose

• Emergency: If you experience symptoms of a serious allergic reaction (e.g., rash, itching/swelling, severe dizziness, trouble breathing), seek immediate medical attention. For other emergencies such as a prolonged erection (priapism) or sudden decrease/loss of vision or hearing, contact your healthcare provider or go to the nearest emergency room.
• Overdose:
  • Taking more than the prescribed dose of Cialis can increase the risk of side effects and complications.

What other information should I know?

• Effectiveness: Cialis works by increasing blood flow to the penis during sexual stimulation, helping to achieve and maintain an erection. It does not protect against sexually transmitted diseases (STDs) or serve as a form of contraception.
• Alcohol and Grapefruit Juice: Limit alcohol consumption while taking Cialis, as excessive alcohol can increase the risk of side effects such as dizziness, headache, or changes in blood pressure. Avoid consuming grapefruit or grapefruit juice while taking Cialis, as it may increase the levels of tadalafil in your blood and lead to potentially serious side effects.
• Follow-Up: Attend scheduled follow-up appointments with your healthcare provider to monitor your response to Cialis and discuss any concerns or changes in your health.
• Interactions: Inform all healthcare providers (doctors, dentists, pharmacists) about all medications you are taking, including Cialis, to avoid potential drug interactions.
