If you’ve heard of "the weekend pill" or see it mentioned alongside Viagra, you’re probably looking at tadalafil. It’s a prescription medicine that helps men get and keep an erection when they’re sexually aroused. The drug belongs to a class called PDE5 inhibitors, which relax blood vessels in the penis so blood can flow in more easily. The result is a firmer, longer-lasting erection that can last up to 36 hours – that’s why many call it the “long‑acting” option.
When sexual stimulation occurs, the body releases a chemical called nitric oxide. Tadalafil blocks an enzyme (PDE5) that would normally break down another chemical, cGMP, which is needed for the vessels to stay relaxed. By keeping cGMP around longer, the blood vessels stay open and the penis fills with blood.
It’s not just for erectile dysfunction (ED). Doctors also prescribe it for benign prostatic hyperplasia (BPH) – an enlarged prostate that makes it hard to urinate. Some men use the same dose for both conditions, which can simplify their routine.
The most common starting dose for ED is 10 mg taken before sexual activity. If that works well, you can increase to 20 mg, but you shouldn’t take more than one dose per day. For daily use (to avoid timing the pill), doctors may prescribe 2.5 mg or 5 mg every day. The dose for BPH is usually 5 mg once a day.
Remember: tadalafil only works with sexual arousal. It won’t cause an erection just by taking the pill. Also, avoid taking it with nitrates (often prescribed for chest pain) because the combination can cause a dangerous drop in blood pressure.
Common side effects include headache, upset stomach, back pain, and facial flushing. These usually fade after a few hours. If you get a painful erection that lasts more than four hours (priapism), seek medical help right away.
When you’re ready to buy tadalafil, look for a reputable online pharmacy that requires a prescription. Check for clear contact details, a licensed pharmacist, and secure payment options. Compare prices, but beware of deals that sound too good to be true – they often sell counterfeit pills that could be unsafe.
Before you order, have a recent prescription on hand, and be ready to answer basic health questions. The pharmacy should verify your doctor’s details and confirm the dosage you need. A legitimate site will also provide information on how to store the medication and what to do if you miss a dose.
Talk to your doctor if you have heart disease, low blood pressure, or are taking other meds that might interact with tadalafil. Your doctor can adjust the dose or suggest an alternative if needed.
In short, tadalafil is a reliable option for many men dealing with ED or BPH, but it works best when you follow the prescribed dose, watch for side effects, and buy from a trusted source. Stay informed, ask questions, and enjoy the confidence that comes with knowing you’ve got a solid plan for better performance.
