Kare Sildenafil Citrate Rapid Dissolve Tablet review

Textbook clinical safety copy, five published strengths, and the dietary supplement disclaimer on a prescription drug

Best for: Men who already have a prescriber and want a compounding pharmacy that documents the drug properly← All reviews

Our verdict

The best-structured safety information in this comparison, attached to the wrong regulatory disclaimer and a price you cannot see. It is the only page here that gives side effects with frequency bands, names riociguat, calls a four-hour erection a medical emergency, publishes an exclusion list and names tamsulosin by name. Then it signs off with the dietary supplement disclaimer — “not intended to diagnose, treat, cure, or prevent any disease” — on a prescription drug whose entire purpose is to treat a disease.

Safety checks

The same seven checks for every service on this site, all read off its public page. The first matters most: ED medication taken with nitrates can cause a life-threatening drop in blood pressure, so a page that never mentions it is leaving out the one thing that could kill you.

  • Discloses the nitrate interaction: Yes

    “Do not use if you take medicines called nitrates (for chest pain) … the mix can cause dangerous drops in blood pressure.” It explains what a nitrate is for, which helps a man recognise his own prescription, and gives the consequence. Riociguat is named separately with the same explanation — one of only a handful of pages here that covers it.

  • Warns about erections lasting over four hours: Yes

    “An erection lasting longer than 4 hours (priapism) is a medical emergency.” The threshold, the name of the condition and the instruction, in one sentence. It also appears in the serious-effects list alongside chest pain and shortness of breath.

  • Lists side effects on the page: Yes

    The only frequency-banded list in this comparison: “Very common (more than 1 in 10): headache. Common (1–10 in 100): flushing, stuffy or runny nose, indigestion, mild dizziness, vision changes such as blue tint or blurred sight. Uncommon (1–10 in 1,000): rash, eye irritation, tiredness, dry mouth.” That is leaflet-grade — it tells you not just what can happen but how likely it is.

  • Raises heart disease and blood pressure: Yes

    An exclusion, not a caution: “Do not use if you have severe heart or liver problems, very low blood pressure, recent stroke or heart attack.” Alpha-blockers are covered with a named example — “(e.g., tamsulosin), causing dizziness — your doctor may need to adjust doses” — and blood pressure medicines, alcohol and grapefruit are all flagged as compounding the effect.

  • States it is compounded and not FDA-approved: Partly

    The right sentence is present — “Compounded products are not FDA-approved” — and it is wrapped in the wrong one. “These statements have not been evaluated by the Food and Drug Administration (FDA)” and “not intended to diagnose, treat, cure, or prevent any disease” are the dietary supplement disclaimer, which is false of a prescription drug dispensed to treat erectile dysfunction. No section 503A or 503B reference either, so a reader cannot tell what kind of compounder this is.

  • Publishes the actual doses: Yes

    All five strengths published: 17, 36, 60, 80 and 115 mg. Non-standard numbers, which is what compounding is for. Worth noting that 115 mg is above the 100 mg maximum of approved oral sildenafil, and the page does not comment on that.

  • States cancellation terms before you buy: No

    No billing terms, no subscription terms and no cancellation process on the page. A refund policy is linked in the footer. There is also no price, so there is nothing for any of it to attach to.

Good fit if

  • Men who already have a prescriber and want the drug dispensed by a pharmacy that documents it properly
  • Anyone who wants the side effects with actual frequencies rather than a vague list
  • Men who need a non-standard strength that an off-the-shelf tablet does not offer

Look elsewhere if

  • You want to know the price before creating an account
  • You need someone to prescribe for you — the page does not say whether they do
  • You want the regulatory position stated in the correct terms
  • You want an ordinary approved strength, which a normal pharmacy will fill more cheaply

It gets almost everything right

Run our seven checks against this page and the first four come back clean, which has happened once before in this comparison.

Nitrates, with an explanation of what they are for — *“medicines called nitrates (for chest pain)”* — which matters because a man reading his own bottle sees “isosorbide mononitrate”, not the word nitrate. Riociguat named separately, which most of this category has never heard of. Which medicines count.

Priapism, stated properly: *“An erection lasting longer than 4 hours (priapism) is a medical emergency.”* The threshold and the instruction in the same breath.

An exclusion list: *“Do not use if you have severe heart or liver problems, very low blood pressure, recent stroke or heart attack, or certain inherited eye diseases such as retinitis pigmentosa.”* Retinitis pigmentosa is a genuine contraindication for this drug class that we have not seen named anywhere else here.

And alpha-blockers with a worked example — *“(e.g., tamsulosin), causing dizziness — your doctor may need to adjust doses”* — plus grapefruit and alcohol as things that push blood pressure down further. What the common effects feel like.

And then signs off as a vitamin

Here is the closing disclaimer, in full:

“These statements have not been evaluated by the Food and Drug Administration (FDA). Compounded products are not FDA-approved and are not intended to diagnose, treat, cure, or prevent any disease.”

The middle clause is correct and important: compounded products are not FDA-approved. Keep that.

The rest is the dietary supplement disclaimer — the sentence required on a bottle of fish oil — and it is wrong twice over here. This is prescription sildenafil. It is dispensed against a prescription *because* it is intended to treat a disease, and the page has just spent several hundred words explaining exactly which disease and what it does to your blood pressure.

We have seen this pattern once before, on a product page belonging to a company whose own advertising destination uses the correct wording instead. It reads as a template problem rather than an intention — but on a page this careful about everything else, it is a strange thing to leave standing. Why the wrong disclaimer is a red flag.

Pricing changes often — check the current figure.

Five strengths, and one of them is over the ceiling

The page publishes every strength it offers: 17, 36, 60, 80 and 115 mg. Nineteen services in this comparison will not tell you a single number, so this is a real credit.

Two things are worth understanding about those figures. They are deliberately non-standard — approved sildenafil comes in 25, 50 and 100 mg — and that is what a compounding pharmacy is for: a dose an off-the-shelf tablet cannot give you, chosen by a prescriber for a reason.

But 115 mg is above the 100 mg maximum of approved oral sildenafil, and the page does not remark on it. A rapid dissolve tablet is absorbed differently from a swallowed one, so a higher number is not automatically a higher effective dose — and that is precisely the explanation a reader needs and does not get. If a prescriber puts you on 115 mg, ask what it is intended to be equivalent to.

The price is behind a login

“Sign in to see instant pricing.” That is the whole of the commercial information on this page.

For a pharmacy dispensing against a prescription this is more defensible than it would be on a consumer landing page — pricing genuinely can depend on the prescription and the payer. But it still means you cannot compare this against anything without creating an account, and there is no subscription or cancellation language of any kind to tell you what you would be signing up to. Why an unpriced page cannot be ranked.

Who you are dealing with

A street address at 411 Park Ave, Danville, Virginia, and a LegitScript approval with a verification link — not just a seal graphic, but a route to check it. That is better than almost everything in this comparison.

What is missing is the pharmacy licence number and, more usefully, any statement of whether this is a 503A compounder — mixing to individual prescriptions — or a 503B outsourcing facility. The pharmacy in this comparison that documents itself best names its statute explicitly, and it is the difference between two quite different regulatory regimes. How to check a service is legitimate.

The page also does not say whether Kare will prescribe for you or whether you need to arrive with a prescription already written. There is a refill request and a transfer form, which suggests the latter.

The bottom line

If you already have a prescriber and need a compounded strength, this is a pharmacy that documents the drug better than any consumer brand in this comparison. The safety section alone is worth reading even if you buy elsewhere.

Two things to sort out before you order: find out what it costs, which means making an account, and ask your prescriber about the strength — particularly if the number on your script is 115.

What is good

  • The only page in this comparison that gives side effects with frequency bands — “Very common (more than 1 in 10): headache”, “Common (1–10 in 100)”, “Uncommon (1–10 in 1,000)” — which is how a patient leaflet does it
  • Names riociguat alongside nitrates, and gives the same consequence for both: dangerous drops in blood pressure
  • States the four-hour rule and then says plainly that it “is a medical emergency”
  • Publishes a real exclusion list: severe heart or liver problems, very low blood pressure, recent stroke or heart attack, retinitis pigmentosa, and allergy to sildenafil
  • Names tamsulosin as an example alpha-blocker, and flags grapefruit and alcohol as things that lower blood pressure further
  • Names sudden loss of vision or hearing, chest pain and shortness of breath as the rare serious effects
  • Publishes all five available strengths rather than hiding them behind “personalised”
  • Publishes a street address in Danville, Virginia and carries a LegitScript approval with a verification link
  • No testimonials, no scarcity language and no urgency of any kind

What is not

  • Uses the dietary supplement disclaimer on a prescription drug — “not intended to diagnose, treat, cure, or prevent any disease” is the wrong instrument entirely for compounded sildenafil
  • No price at all: “Sign in to see instant pricing” puts the cost behind an account
  • The 115 mg strength is above the 100 mg maximum of approved oral sildenafil, and the page does not remark on it
  • Does not say whether it prescribes or whether you must bring your own prescriber
  • No subscription or cancellation terms, and the refund policy is linked rather than summarised
  • No pharmacy licence number, and no section 503A or 503B reference to say which kind of compounder it is
