10 OVERDOSAGE

But the downside is you’ll need to remember to take the medication every day, and you may experience more persistent side effects. Check out our guide to daily-use Cialis to learn more. The benefit of a higher-dose as-needed treatment like Cialis 20 mg is you don’t have to take the medication every day, so you don’t have to worry about missed doses. But the higher your dose, the more likely it is you’ll experience side effects. A healthcare provider can recommend the best Cialis dosage for you. FYI: You can’t buy Cialis over the counter. You’ll need to talk with a healthcare professional and get the ED medication prescribed (if you’re deemed eligible for treatment). Remember that brand-name Cialis will typically cost more than tadalafil, even though the medications are the same. As tempting as they can be, steer clear of non-prescription Cialis substitutes.

Cialis 20 mg is an as-needed ED treatment.

12.3 Pharmacokinetics

While Cialis works similarly to Viagra®, Cialis lasts longer in your body. In fact, Cialis is known as the “weekend pill” for its long half-life. Because you can pop one pill and have sex whenever you like over the next 36 hours (give or take a few hours), it offers more spontaneity. In comparison, avanafil only lasts up to six hours, and Viagra only lasts up to four hours. Clinical trials show that Cialis is effective for various severities and types of ED, including difficult-to-treat ED.

Does Cialis work and is it safe?

If you find Cialis 10 mg isn’t working, a 20 mg tablet might do the trick. You don’t need to take it every day. Depending on your preference and lifestyle, you may not want to take Cialis day in and day out. In fact, the 20 mg dose of Cialis should only be taken as needed. Side effects of Cialis are usually mild and should go away on their own — although they may be worse with higher doses.

Does tadalafil interact with other medicines (drug interactions)?

For example, in clinical trials, 11 percent of people taking tadalafil 10 mg got a headache, whereas 15 percent of those taking tadalafil 20 mg got a headache. Some side effects have the same likelihood in both doses, such as flushing and limb pain. If the side effects of Cialis 20 mg are too much, a healthcare provider may reduce your dose. If this is a particularly annoying side effect of other ED medications, switching to Cialis may be the answer. A 2017 systematic review and meta-analysis compared sildenafil (the generic of Viagra) and tadalafil. You’ll take it at least 30 minutes before having sex.

Medication	Dosage Forms	Onset Time	Duration	Price (approx.)
Cialis 20mg	Tablets	30-60 minutes	Up to 36 hours	Moderate
Viagra 50mg	Tablets	30-60 minutes	4-6 hours	Moderate
Levitra 10mg	Tablets	30 minutes	4-5 hours	Slightly higher
Stendra 100mg	Tablets	15-30 minutes	6 hours	Higher

It should provide ED relief for up to 36 hours, allowing you to have sex on your schedule.

2.2 Use with Food

It found that tadalafil caused lower rates of flushing. Muscle aches and back pain were more common in tadalafil than sildenafil, though. Overall, tadalafil and sildenafil had similar efficacy and safety, but men and their partners preferred tadalafil. You can learn more about the two ED treatments in our Cialis vs. Viagra guide.

ED dosage for daily use

As with any medication, Cialis comes with possible side effects. The most common Cialis side effects include: Clinical trials show that most side effects are dose-dependent, meaning you’re more likely to get them with higher doses — and remember, Cialis 20 mg is the highest dose of the drug. Allergic reactions to Cialis aren’t common but they’re possible. Swelling of the lips, tongue, or throat Swelling of the lips, tongue, or throat There’s also a risk of priapism or prolonged erections — we’re talking for several hours here. It may sound great if you’re suffering from ED, but prolonged erections can be painful and cause irreversible damage to the penis.

How Long Does It Take For Results?

If your erection lasts more than four hours, seek medical advice. You may be more likely to get prolonged, painful erections from Cialis if you have: Anatomic deformations in the penis (like Peyronie’s disease) Anatomic deformations in the penis (like Peyronie’s disease) There’s also a small risk of vision loss. If you notice any vision loss in one or both eyes, stop taking Cialis and seek medical help. This could be a sign of non-arteritic anterior ischemic optic neuropathy (NAION), which is caused by a lack of blood flow to the optic nerve. Another serious side effect includes a sudden decrease in hearing or hearing loss. You might get a headache, indigestion, or backache. Not ideal when you’re trying to have some sexy time, but these side effects should be mild.

Side Effects

Again, get medical advice as soon as you notice this. There are also a few drug interactions you should know about. You shouldn’t take Cialis 20 mg (or any dose of the drug) at all if you’re taking nitrates. The combo can cause your blood pressure to drop suddenly, resulting in dizziness, loss of consciousness, or even a heart attack or stroke. Nitrates can be found in medications like isosorbide dinitrate or isosorbide mononitrate, which are used to treat prevent angina caused by heart disease.

Dosage for benign prostatic hyperplasia (BPH)

Also, watch out for recreational drugs that contain nitrates, like “poppers.” You also shouldn’t take Cialis if you take medications called guanylate cyclase stimulators, such as riociguat, which treats pulmonary hypertension. If you’re taking alpha-blockers (like doxazosin, tamsulosin, or alfuzosin) — which mainly treat high blood pressure or BPH — or CYP3A4 inhibitors (like the antibiotic erythromycin and the antifungal medication ketoconazole), which treat a wide variety of conditions, you may be prescribed a low dose of Cialis—probably not the 20 mg kind. It’s unclear whether it’s safe to take Cialis 20 mg or any dose of the drug with other PDE5 inhibitors, such as: Tell your prescribing healthcare provider about the medications or supplements you’re taking before trying Cialis. Beyond medications, watch out for how much you drink when you’re taking Cialis. If you have five or more alcoholic drinks, you may experience: And a weird one to watch out for: grapefruit and Cialis.

Oral Administration

A 2020 study on rats found that grapefruit juice inhibits tadalafil metabolism — remember, that’s the active ingredient in Cialis. This can lead to you having more tadalafil in your system, which can increase your risk of side effects. You can learn more about what to avoid in our guide to tadalafil interactions. Finally, tell a healthcare provider about any medical conditions you have before taking Cialis so they can determine whether it’s safe for you. Heart problems like angina (chest pain caused by reduced blood flow to the heart), heart disease, or irregular heartbeats Heart problems like angina (chest pain caused by reduced blood flow to the heart), heart disease, or irregular heartbeats Cialis is available in a range of doses. Speak to a healthcare provider if any side effects bother you. They may recommend a lower Cialis dose. Cialis 20 mg isn’t your only option. There’s Viagra or sildenafil, Stendra, and Hims Hard Mints, which can contain the active ingredients in Cialis and Viagra in personalized dosages. You’ll need a prescription for Cialis 20 mg — or any other PDE5 inhibitor.

Proper Use

Here’s what they’re usually prescribed for: Cialis 2.5 mg: If you’re taking Cialis daily, you might be prescribed a 2.5 mg dose. If 2.5 mg isn’t effective and you don’t have any bothersome side effects, the dose may be increased to 5 mg.
