Sildenafil 25 mg to 250 mg tablets, chewables and capsules

Usually about 30 to 60 minutes, which is why the label suggests taking it around an hour before sexual activity. A large or fatty meal slows absorption and can push that back by roughly an hour, so an emptier stomach gives a more predictable start. The effect is generally there for about four hours, though that varies between people. Sexual stimulation is still required — the tablet does not produce an erection by itself. If nothing happens after several separate attempts, speak to your prescriber rather than adding a second tablet.

Both are PDE5 inhibitors and both need sexual stimulation to work. The practical difference is timing. Sildenafil is usually taken around an hour beforehand and its effect lasts roughly four hours, and food delays its onset. Tadalafil works for up to 36 hours from a single dose, is not affected by food, and also comes in a low daily dose. Neither is better than the other in the abstract — the fit depends on your health, your other medicines and how you would rather use it, which is a conversation for your prescriber.

A small amount is unlikely to cause a problem for most people, but alcohol works against you here in two ways. It is itself a common cause of difficulty getting an erection, so it can make the tablet look like it failed. It also lowers blood pressure, adding to the same effect from sildenafil, which can leave you dizzy or faint. Heavy drinking makes both worse. If you take blood pressure medicines or an alpha-blocker as well, ask your prescriber or our pharmacist about your own situation.

Because the combination can drop your blood pressure far and fast. Nitrates and sildenafil both act on the same pathway that relaxes blood vessels, and together the effect is multiplied — the result can be collapse, a heart attack or a stroke. This is an absolute contraindication on the label, not a caution. It covers prescribed nitrates for angina in every form, and recreational nitrites known as poppers. If you develop chest pain after taking sildenafil, tell the emergency team you have taken it, because it changes what they can give you.

No. Sildenafil is a prescription-only medicine and we dispense it only against a valid prescription from your licensed prescriber. There are good reasons for that: sildenafil is absolutely contraindicated with nitrates, interacts with alpha-blockers and several common antibiotics and antifungals, and erectile dysfunction is sometimes the first visible sign of heart disease or diabetes that needs investigating. A licensed pharmacist reviews every order here and will contact you or your prescriber if anything needs clarifying.

We dispense sildenafil as 25 mg (10 tabs), 50 mg (10 tabs), 100 mg (10 tabs), 100 mg (4 tabs), 120 mg (5 tabs), 150 mg (10 tabs), 200 mg (10 tabs), 250 mg (10 tabs), 100 mg chewable (10 tabs), 100 mg chewable (4 tabs), 100 mg sublingual (10 tabs) and 100 mg soft gel (10 capsules). The current price for each pack is shown on this page and again in your cart before you pay, with no membership fee and no tiers. Stock may be branded or generic on any given day, depending on what is in supply; the active ingredient, the strength and the pack size are what the label says either way. What we dispense is set by your prescription rather than by what you select, so if the quantity on your prescription differs from the pack you picked, our pharmacist will contact you before anything is sent.

We dispense only where we are licensed to dispense, and the checkout tells you whether we can ship to your address before you pay. If we cannot, you will not be charged. Orders go out in plain outer packaging with no indication of the contents, and the pharmacy name appears only where the law requires it on the dispensing label inside. Delivery timing depends on your address and on how quickly your prescription can be verified. Current carriers and windows are on our shipping page.

That is a judgement only your prescriber can make. The relevant point on the label is that sexual activity itself puts strain on the heart, so treatments for erectile dysfunction should not be used by men for whom sexual activity is inadvisable. Sildenafil is contraindicated with nitrates, which many people with angina take, and it adds to the effect of blood pressure medicines. Tell your prescriber about any heart attack, stroke, angina, heart rhythm problem or blood pressure treatment, and give our pharmacist your full medicine list.
