Frequently asked questions about Tadalafil
-
Tadalafil (Cialis) is a well-established medication that is primarily utilized to address erectile dysfunction (ED), often referred to as impotence, which is characterized by the inability to achieve or maintain an erection during sexual activity. Furthermore, tadalafil is also effective in alleviating the symptoms associated with benign prostatic hyperplasia (BPH), a condition involving an enlarged prostate, resulting in difficulties with urination including hesitation, dribbling, a weakened urinary stream, and not being able to completely empty the bladder. Other symptoms of BPH that tadalafil can help mitigate include painful urination, and the frequent and urgent need to urinate, especially in adult males. Additionally, tadalafil (marketed under the name Adcirca) is indicated for improving exercise capacity in individuals diagnosed with pulmonary arterial hypertension (PAH), a serious condition characterized by elevated blood pressure in the pulmonary arteries, which can lead to symptoms such as shortness of breath, dizziness, and extreme fatigue. This medication is classified as a phosphodiesterase type 5 (PDE5) inhibitor, working to ameliorate erectile dysfunction by enhancing blood flow to the penis in response to sexual stimulation, leading to the ability to achieve an erection.
It's essential to understand that while tadalafil can be an effective treatment for erectile dysfunction, it does not cure the condition nor does it heighten sexual desire. Furthermore, it is important to note that tadalafil does not provide protection against pregnancy or sexually transmitted diseases, including human immunodeficiency virus (HIV).

Tadalafil is administered in the form of a tablet that is intended to be taken orally. It can be consumed either with or without food, which provides flexibility for users in terms of their dietary habits.
When using tadalafil to treat erectile dysfunction, adhering to your doctor’s recommendations as well as the instructions outlined in the accompanying material is of utmost importance. Tadalafil can be taken in two distinct regimens—either on a daily basis or as needed, depending on your doctor's guidance. If taken on an as-needed basis, it is generally suggested to take it at least 30 minutes prior to sexual activity and no more frequently than once every 24 hours. Your healthcare provider will help determine the optimal timing for taking tadalafil before engaging in sexual activities. Alternatively, for those who prefer to take tadalafil on a daily schedule, it can be taken once daily regardless of sexual activity timing. In this case, you are free to engage in sexual activity at any interval between doses. If following the regular schedule, it’s advisable to take tadalafil at approximately the same time each day to maintain consistency. In cases where certain health conditions are present or if other medications are being used, your healthcare provider may recommend reducing the frequency of tadalafil intake or adjusting the dosage. Always follow the instructions provided on the prescription label closely, and if there’s any aspect that remains unclear, reach out to your healthcare provider or pharmacist for clarification. It’s critical to take tadalafil strictly as directed—do not exceed or undercut the prescribed dose, and do not take it more often than what has been advised by your healthcare professional.
In the context of erectile dysfunction treatment, your doctor will likely start you on a typical dose of tadalafil and may adjust it based on your individual response to the medication. Ensure to promptly communicate with your healthcare provider if you find that tadalafil is not sufficiently effective, or if you encounter any adverse effects.
-
Before commencing treatment with tadalafil,
-
it's essential to inform your healthcare provider and pharmacist whether you have any allergies to tadalafil, other medications, or specific ingredients contained within the tadalafil tablets. You can request a comprehensive list of these ingredients from your pharmacist.
-
Notify your doctor if you are currently taking or have recently taken riociguat (Adempas) or any nitrates, such as isosorbide dinitrate (Isordil), isosorbide mononitrate (Monoket), and nitroglycerin (Minitran, Nitro-Dur, Nitromist, Nitrostat, and various others). These nitrates can be found in different forms such as tablets, sublingual tablets, sprays, patches, pastes, and ointments. Reach out to your healthcare provider if you are unsure whether any of your medications contain nitrates, as they may advise against taking tadalafil concurrently with nitrates.
-
It is vital to inform your doctor if you are using recreational drugs that contain nitrates (often referred to as 'poppers'), such as amyl nitrate, butyl nitrate, or nitrite while on tadalafil. Your healthcare provider will likely recommend refraining from tadalafil use if you are consuming such street drugs containing nitrates.
-
Be aware that tadalafil is marketed under the brand names Adcirca and Cialis, and you should only be treated with one of these drugs concurrently to avoid potential complications.
-
Additionally, inform your doctor and pharmacist regarding any other prescription and over-the-counter medications, vitamins, and supplements you are currently taking or plan to initiate. Be especially vigilant in mentioning medications that fall into specific categories such as alpha-blockers like alfuzosin (Uroxatral), doxazosin (Cardura), dutasteride (Avodart, in Jalyn), prazosin (Minipress), silodosin (Rapaflo), tamsulosin (Flomax, in Jalyn), and terazosin; antifungals like fluconazole (Diflucan), griseofulvin (Grifulvin, Gris-PEG), itraconazole (Onmel, Sporanox), ketoconazole (Extina, Ketozole, Nizoral, Xolegel), and voriconazole (Vfend); and other medications used for conditions such as hypertension. Your healthcare professional may need to adjust your medication dosages or monitor you closely for any side effects.
-
Ensure to disclose any herbal products you may be taking, particularly St. John’s wort, to your healthcare provider.
-
Additionally, let your doctor know if you smoke or if you have ever experienced an erection that lasted longer than four hours. It's also important to report any recent episodes of diarrhea, vomiting, insufficient fluid intake, or excessive sweating which could indicate dehydration. Disclose any history of pulmonary veno-occlusive disease (PVOD), any conditions impacting the anatomy of your penis, diabetes, cholesterol issues, irregular blood pressure, cardiac concerns, or any chronic illnesses affecting your organs. Notifying your doctor regarding family medical history concerning eye diseases like retinitis pigmentosa is also crucial, especially if you or your family members have encountered sudden severe visual impairment.
-
If you are scheduled for any form of surgery, including dental procedures, it is imperative to inform the attending physician or dentist about your tadalafil usage.
-
Discuss the implications of alcohol consumption with your doctor while undergoing treatment with tadalafil. Excessive alcohol intake (more than five glasses of wine or five shots of whiskey) may increase the likelihood of experiencing adverse reactions to tadalafil, such as dizziness, headaches, rapid heartbeat, and lowered blood pressure.
-
For those taking tadalafil to manage erectile dysfunction, it's vital to inform your healthcare provider if you've ever been advised to avoid sexual activity for medical reasons or if you have a history of experiencing chest pain during sexual intercourse. Engaging in sexual activity can exert strain on your heart, particularly for individuals with pre-existing heart conditions. Should you experience chest pain, dizziness, or nausea during sexual activity, it is critical to contact your physician immediately or seek emergency medical assistance, and refrain from sexual activity until instructed otherwise by your healthcare provider.
-
Ensure that all healthcare professionals involved in your care are aware of your tadalafil use. In any situation requiring emergency medical attention for a heart-related issue, it's crucial for the attending healthcare providers to be informed of your most recent tadalafil administration.
-
-
Engage in a dialogue with your healthcare provider regarding the consumption of grapefruit and drinking grapefruit juice while on this medication, as these can interact with tadalafil.
-
If you are adhering to a regular schedule of tadalafil for erectile dysfunction and find that you have missed a dose, take it as soon as you remember. However, if the timing is close to your next dose, skip the missed dosage and proceed with your usual dosing schedule. Do not double up on doses or exceed one dose per day to compensate for a missed one.
-
Like all medications, tadalafil may lead to side effects. Notify your doctor if any of the following symptoms become severe or persistent:
headaches
indigestion or discomfort in the digestive tract
nausea
diarrhea
facial flushing
muscle or joint pain
coughing
In some instances, side effects can escalate to serious conditions. Should you encounter any of the following symptoms, reach out to your healthcare provider promptly or seek immediate medical assistance:
sudden decline or complete loss of vision (refer to additional information below)
blurriness in vision
changes in color perception (such as seeing a blue tinge to objects or having difficulty distinguishing between blue and green)
sudden decrease or loss of hearing (more information on this follows)
ringing sensations in the ears
erections lasting longer than four hours
experiencing dizziness
chest discomfort
hives or skin rashes
difficulty in breathing or swallowing
facial swelling (including throat, tongue, lips, eyes, hands, and feet)
skin blistering or peeling
Some patients have experienced a sudden loss of either partial or complete vision after administering tadalafil or similar drugs. In some reported cases, this vision loss has been irreversible. The correlation between this vision loss and the medication remains undetermined. If you experience sudden vision loss while taking tadalafil, seek immediate medical attention without consuming any further doses of tadalafil, sildenafil (Revatio, Viagra), or vardenafil (Levitra) until you consult your doctor.
Similarly, there have been cases where patients reported sudden hearing loss following tadalafil use. This usually occurred in a single ear and did not necessarily improve upon discontinuation of the medication. Again, the relationship between the hearing loss and the drug remains unclear. If sudden hearing loss occurs, often accompanied by ear ringing or dizziness, seek urgent medical care and avoid other PDE5 inhibitors until after discussing with your doctor.
Be aware that other side effects may occur. Should you encounter any unusual issues while taking tadalafil, contact your healthcare provider for advice.
For serious side effects, you or your physician may report incidents to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program, accessible online or via phone.
-
Store this medication in its original container, keeping it tightly secured and away from the reach of children. Ideal storage conditions include a room-temperature environment, away from excessive heat and moisture—avoid storing it in bathrooms where humidity is prevalent.
Should you have any unused medications, they should be disposed of appropriately to prevent accidental ingestion by pets or children. Flushing medications down the toilet is not advisable. The recommended disposal method is through a community medicine take-back program. Consult your pharmacist or local waste management contacts to identify take-back options in your area. More disposal guidelines can be found on the FDA's Safe Disposal of Medicines webpage.
It is critical to store all medications out of sight of children, as some containers (e.g., those for weekly pill organizers, eye drops, creams, patches, and inhalers) may not be child-proof and can be easily accessed by young children. To prevent potential poisoning, always secure safety caps, and promptly place medications in child-proof locations that are not visible or reachable by children.
-
In case of an overdose, it is crucial to contact the poison control helpline immediately. If the individual has collapsed, is experiencing seizures, displays difficulty breathing, or cannot be awakened, call emergency services without delay.
-
Always keep your appointments with your healthcare provider to ensure continuous monitoring of your treatment.
Never share your medication with anyone else. Should you have questions regarding prescription refills or more information, don't hesitate to ask your pharmacist.
It is important to maintain a detailed record of all prescription and non-prescription medications you are currently using, alongside any dietary supplements. Bring this comprehensive list to every doctor's appointment or when checking into a hospital. This information is also vital to carry with you for emergency situations.
