Caverta Explained: Uses, Dosage, Side Effects, Price & How It Stacks Up Against Viagra

Maya Tillingford 0 Comments

TL;DR:

  • Caverta is a brand‑name tablet that contains sildenafil, the same active ingredient as Viagra.
  • Typical dose is 50mg taken about an hour before sexual activity; 100mg is a possible maximum.
  • Common side effects include headache, flushing, upset stomach - serious reactions are rare but need urgent care.
  • In the UK it’s a prescription‑only medicine; cost ranges £30‑£45 per tablet through private pharmacies.
  • Alternatives include Viagra, Cialis (tadalafil) and lifestyle changes; choose based on onset, duration and personal health.

What is Caverta?

Caverta is a prescription tablet marketed primarily for treating erectile dysfunction (ED). The drug’s active ingredient is sildenafil citrate, the same molecule you’ll find in the well‑known brand Viagra. Sildenafil works by inhibiting an enzyme called phosphodiesterase‑5 (PDE5), which relaxes blood vessels in the penis and allows blood to flow in when a man is sexually aroused.

Although the chemistry matches Viagra, Caverta is sold under a different brand name and often appears in private‑prescription formularies across the UK. It is not an over‑the‑counter product, and a doctor’s clearance is required before you can obtain it.

How to Take Caverta Safely

Using Caverta correctly maximises effectiveness while keeping risks low. Follow these steps:

  1. Get a prescription. Book an appointment with a GP or a licensed sexual‑health clinic. They’ll check your blood pressure, heart health and medication list.
  2. Decide on the dose. The standard starting dose is 50mg. If you tolerate it well, a doctor may raise it to 100mg; the minimum is 25mg for men who need a gentler effect.
  3. Take the tablet with a glass of water about 30‑60 minutes before you plan to have sex. Food, especially high‑fat meals, can delay absorption and make the onset slower.
  4. Don’t exceed one dose in a 24‑hour period. Taking more won’t improve results and increases side‑effect risk.
  5. Plan for the window. Sildenafil’s effects last roughly 4‑6hours, giving you a fairly flexible timeframe, but the peak usually hits between 60‑90minutes.

If you miss a dose (which is unlikely with an “as‑needed” medication), simply skip it and wait for the next occasion. Never take a double dose to make up for a missed one.

Side Effects and Who Should Avoid It

Most men experience mild, short‑lived side effects. The most frequently reported ones are:

  • Headache (about 10% of users)
  • Facial flushing
  • Indigestion or upset stomach
  • Runny or blocked nose
  • Transient visual changes (a bluish tint or blurred vision)

Serious adverse events are rare but worth knowing:

  • Sudden vision loss (non‑arteritic anterior ischemic optic neuropathy)
  • Priapism - a painful erection lasting more than 4hours
  • Severe chest pain or heart rhythm problems, especially if you have underlying cardiovascular disease

People who should NOT take Caverta include:

  • Anyone using nitrates (e.g., nitroglycerin) for chest pain - the combo can cause dangerous blood‑pressure drops.
  • Men with severe heart failure, unstable angina, or recent heart attack.
  • Those with a known allergy to sildenafil or any tablet excipients.

Always discuss your full medical history with a doctor before starting.

Price, Availability and Buying Tips in the UK

Price, Availability and Buying Tips in the UK

Because Caverta is prescription‑only, you’ll need a valid NHS or private prescription to pick it up. Private pharmacies tend to carry it, and the price varies by supplier and quantity.

QuantityTypical Cost (GBP)Per‑tablet Cost
4 tablets (50mg each)£120‑£150£30‑£38
8 tablets (50mg each)£210‑£260£26‑£33
10 tablets (100mg each)£280‑£320£28‑£32

Key buying tips:

  • Ask your pharmacist if they offer a *generic* sildenafil option - it’s often cheaper and identical in effect.
  • Beware of online “no‑prescription” sellers; they may dispense counterfeit medication.
  • Check if your private medical insurance covers ED medication - some policies reimburse part of the cost.

Supply chains have been stable in 2025, so you shouldn’t face significant shortages, but ordering a month’s supply ahead can save you a trip.

Alternatives and When to See a Doctor

If Caverta isn’t working for you, several options exist:

  • Viagra (sildenafil) - identical active ingredient but often marketed at a higher price point.
  • Cialis (tadalafil) - longer onset (up to 2hours) and a 36‑hour “window”, useful for spontaneous activity.
  • Stendra (avanafil) - quicker onset (15‑30minutes) and fewer visual side effects.
  • Non‑pharmacological approaches - lifestyle changes like weight loss, quitting smoking, and regular exercise can improve erectile function.

Schedule a follow‑up with your GP if:

  • You experience any of the serious side effects listed above.
  • The medication doesn’t produce an erection after a few attempts at the prescribed dose.
  • You have new health issues (e.g., heart problems, uncontrolled hypertension).

In some cases, a specialist urologist may suggest penile injections, vacuum erection devices, or even surgical options.

Mini‑FAQ

  • Is Caverta the same as Viagra? Yes, both contain sildenafil; the difference is branding and pricing.
  • Can I take Caverta with alcohol? Moderate alcohol is usually fine, but heavy drinking can reduce the drug’s effectiveness.
  • How long does Caverta stay in my system? Sildenafil’s half‑life is about 4hours, so trace amounts may linger up to 24hours.
  • Do I need a repeat prescription? Most doctors will issue a short‑term script (4‑8 weeks) and then reassess.
  • Is there a cheaper generic? Yes - look for “sildenafil citrate 50mg” from reputable UK pharmacies.
Next Steps & Troubleshooting

Next Steps & Troubleshooting

If you’re ready to try Caverta, the first move is a GP appointment. Bring a list of current meds, any heart‑related conditions, and questions about dosage. After you’ve got the prescription:

  1. Compare prices at a few local pharmacies - some offer a discount for cash‑only purchases.
  2. Take the first tablet on a night with low stress and no alcohol to gauge your response.
  3. If you notice a mild headache, hydrate and consider a lower starting dose next time.
  4. Should you experience any serious symptoms (e.g., chest pain, prolonged erection), seek emergency care immediately.

Remember, ED is often a sign of broader health issues. Treating the underlying cause-whether it’s blood‑pressure control, weight management, or mental health-can boost your overall results better than any pill alone.
