How to Buy Tadalafil Online

By Nicolette Natale, D.O. • 5 min read • Sep 19, 2025

Tadalafil (the active ingredient in Cialis) is a medication that makes it easier for men with erectile dysfunction (ED) to get and keep erections. Many patients choose TAD over other ED drugs because it stays in your system for up to 36 hours, which is much longer than other medications in this category. In other words, with chewable TAD from BlueChew, you can chew it and do it all weekend long.

How Tadalafil Works

Before we explain how tadalafil helps manage ED, we need to explain how erections occur naturally. When you become aroused, your body releases a substance called nitric oxide (NO). In turn, levels of a chemical known as cyclic guanosine monophosphate (cGMP) increase in your body, relaxing the muscles that line the blood vessels of the penis so blood can flow into the organ and trigger a stiff erection.

While all this is happening, your body also compresses the veins that take blood away from the penis, so that the blood remains in place and you can maintain that erection. Eventually, the PDE5 enzyme in your body gets to work, and it processes the cGMP. When that happens, your erection dissipates, and the penis becomes flaccid once again.

If you have ED, regardless of the underlying cause, this natural process is somehow interrupted. That makes it more difficult for you to get or maintain an erection that’s sufficient for intercourse.

And that’s where TAD (with the active ingredient tadalafil), a PDE5 inhibitor, can help. By blocking this enzyme in your body, you’ll have an easier time getting an erection and maintaining it throughout sex.

Buying Tadalafil Online

This medication is only available with a prescription.

You can get TAD online with a subscription to BlueChew, which connects you to a team of licensed medical providers who can prescribe the medication to you. Our online telehealth platform allows you to access ED pills without leaving your home.

Remember, you can’t legally buy or sell tadalafil online without that prescription, so you should never purchase ED pills from unlicensed providers.

Can I Get My Prescription Mailed to Me?

Absolutely! When you subscribe to a plan with BlueChew, your TAD tablets are prescribed online and delivered directly to your home, after a consultation with licensed medical providers.

Your prescription is unique to you, and can’t be shared with anyone else, even if they live at the same address.

Tadalafil Dosage

We offer prescriptions for 6mg or 9 mg chewable TAD (tadalafil) tablets, allowing for flexible dosing, even for patients who struggle to swallow pills.

The best time to take TAD is at least 30-60 minutes before sex. You can chew your dose with or without food, since what you eat won’t affect its absorption. Once in your system, TAD's effects in your body last for up to 36 hours, meaning it’s a great choice for weekends when the kids are away, and you’re ready to stay in and have some grown up fun.

The long-lasting effects of tadalafil are one of the main reasons why you might choose TAD over sildenafil (the active ingredient in Viagra), which only stays in your body for about four to six hours.

But don’t worry about walking around with visible signs of arousal for that entire period. Even though the medication remains in your body for an extended time period, you should only experience an erection when sexual stimulation occurs.

Side Effects and Contraindications

Before you buy tadalafil online, it’s important to understand that the medication can cause side effects.

Common side effects include

Headaches
Flushed skin
Nausea or stomach upset
Changes in vision
Nasal congestion or dripping
Back pain
Rashes
Dizziness

Most symptoms are mild, but it is important to notify your medical provider if they arise after taking the medication.

Some side effects are more serious. These include an erection that lasts longer than four hours (a condition called priapism) or sudden hearing or vision loss. If you experience these tadalafil side effects, you must seek immediate medical attention.

While TAD is generally well tolerated, you should not take this medication if you:

Also take prescription vasodilator medications, angina medication or medications for pulmonary hypertension
Use street drugs such as amyl nitrite or nitrite, and/or butyl nitrate

During your BlueChew consultation, be sure to discuss all your current medications, and any recreational drug use, so that your licensed medical provider can safely prescribe tadalafil online.

Final Thoughts

Tadalafil (TAD) is more than just another ED medication — it’s a long-lasting, flexible option that gives you up to 36 hours of erection support. That means more freedom, less pressure to “time things perfectly,” and a whole weekend of confidence packed into a single chewable.

While it’s not for everyone, men who prefer spontaneity often find TAD to be the right fit. Just remember: it’s prescription-only, and you should only use it under the guidance of a licensed provider who knows your health history.

At the end of the day, BlueChew makes it easy to get tadalafil safely and discreetly, without pharmacy lines or in-person doctor’s visits.
