Tadalafil: Uses, Dosage, Side Effects, and Safe Use
Tadalafil is a PDE5 inhibitor used for erectile dysfunction (ED), benign prostatic hyperplasia (BPH), and pulmonary arterial hypertension (PAH). It improves blood flow by relaxing blood vessels. Unlike some ED pills, tadalafil can work for up to 36 hours, giving a wider window for intimacy.
For ED most people take tadalafil 10 mg before sex and adjust to 5 mg or 20 mg based on effect and side effects. A daily low dose—usually 2.5 to 5 mg—treats both ED and BPH when constant coverage is preferred. For PAH the dose and schedule differ; follow specialist guidance and the prescription that mentions Adcirca or generic tadalafil for pulmonary use.
How to take tadalafil safely
Take tadalafil as prescribed. If you use the as-needed dose, take it at least 30 minutes before sex—some people need up to 2 hours. Avoid taking higher doses without a doctor’s okay. Don’t mix tadalafil with nitrates (often used for chest pain) — the combo can cause dangerous blood pressure drops. Be cautious with alpha-blockers; start one drug at a low dose and stagger timing under medical advice.
Tadalafil is broken down by CYP3A4. Strong inhibitors like ketoconazole or ritonavir raise tadalafil levels and require dose changes. Grapefruit or grapefruit juice can increase drug levels too; avoid large amounts. Drink alcohol in moderation: heavy drinking raises the chance of dizziness and low blood pressure.
Common side effects include headache, flushing, upset stomach, back pain, and muscle aches. Back and muscle pain can appear 12 to 24 hours after a dose and may last a day or two. Seek immediate care if you have sudden vision loss, sudden hearing loss, chest pain, or an erection lasting more than four hours (priapism).
Buying tadalafil and checking safety
Always use a prescription when possible. If buying online, pick a licensed pharmacy with a visible address, pharmacist contact, and clear prescription requirements. Avoid extremely cheap offers and pills sold without packaging or batch numbers. Check that the product name and dose match your prescription—Cialis is the brand name, tadalafil is the generic. Review UK and local rules if ordering across borders; customs and regulations vary.
Tell your doctor about heart disease, recent stroke or heart attack, low blood pressure, severe liver or kidney problems, or other medications you take. If you have ongoing questions about dosing or interactions, ask a pharmacist or your prescriber. Tadalafil works well for many people when used correctly and safely; getting the right dose and following precautions keeps benefits high and risks low.
Quick tips: keep a pill diary, note how long effects last for you, avoid sharing medication, store tablets in original packaging at room temperature, and check expiry. If you have diabetes or prostate surgery history, mention it to your doctor. Younger men with sudden ED should get a medical check as it can signal cardiovascular issues. When you find a dose that works, stick with it unless advised otherwise. Keep emergency contacts and your prescription handy.
