What is Tadalafil?
Tadalafil is a prescription medicine (generic for Cialis) used to treat erectile dysfunction (ED) in adults. It belongs to a class called PDE5 inhibitors and works by increasing blood flow to help achieve and maintain an erection with sexual stimulation. Dispensed by Serv u Pharmacy only with a valid prescription.
Uses
- Treatment of erectile dysfunction (ED) in adult men
- In some cases, treatment of benign prostatic hyperplasia (BPH) symptoms (when prescribed)
Only your clinician can determine if tadalafil is appropriate for you, especially if you have heart conditions or take medicines that affect blood pressure.
How it’s taken (follow your prescription)
Take exactly as prescribed. Tadalafil may be used “as needed” before sexual activity or as a lower-dose once-daily option, depending on your prescription. Do not take more than directed.
| Form | Strengths (examples) |
|---|---|
| Tablets | 2.5 mg, 5 mg, 10 mg, 20 mg |
Refer to your label for exact dosing. Pharmacist counseling is available at checkout.

- Alpha-blockers / BP meds: Use caution—may increase dizziness or fainting risk (dose timing matters).
- CYP3A4 inhibitors: Some medicines (e.g., ketoconazole, itraconazole, ritonavir, clarithromycin) may raise tadalafil levels—dose adjustments may be needed.

FAQ
Can I buy Tadalafil over the counter? No. In the U.S., tadalafil is prescription-only. Serv u Pharmacy dispenses it only with a valid prescription.
How is tadalafil different from sildenafil? Tadalafil typically lasts longer (up to 36 hours), while sildenafil often has a shorter duration. Your prescriber can help choose what fits your needs and health history.
Can I take tadalafil every day? Some people are prescribed a low-dose daily regimen. Only take it daily if your prescription is written that way.
What if I take chest pain medicine? If you use nitrates for chest pain, tadalafil may not be safe. Tell your prescriber and pharmacist.

Judy Doyle, PharmD — Licensed Pharmacist (NPI 1699814004).
In everyday pharmacy practice, tadalafil’s “secret sauce” is its long duration when used correctly, it often takes pressure off the clock. I counsel a lot of patients who assume they must time it down to the minute like other ED meds, and then they over-dose or mix products. With tadalafil, the more common issue I see is people forgetting it can stay active well into the next day (up to about 36 hours), so they take another dose too soon or add a second ED medication. My practical tip: treat it like a longer-acting medicine stick to the schedule your prescriber wrote, and don’t “stack” doses. Also, if backache or muscle aches show up (a classic tadalafil complaint), good hydration and a simple OTC pain reliever if safe for you often helps, but persistent or severe pain is worth a quick check-in. And just like all PDE5 inhibitors, I always screen for nitrates and “poppers” first if those are on board, tadalafil is not an option.
