Will I get side effects if I take Varimax?

Varimax is generally considered a low-risk medication. Vardenafil, the active ingredient in Varimax, is a PDE5 inhibitor. PDE5 is an enzyme in the body that causes blood vessels to restrict (narrow). By limiting the activity of PDE5, vardenafil encourages blood vessels to dilate (open up).

If you have ED, vardenafil allows blood to more easily enter two shaft-like columns of tissue in the penis (when you’re sexually aroused) allowing you to get an erection. However, vardenafil doesn’t just act on the blood vessels in your penis but throughout your body.

So, most Varimax adverse effects are a result of a change in blood pressure. Vardenafil side effects are not normally something to worry about and will wear off as the body eliminates Varimax from your system after a few hours.

If you have a history of low blood pressure or are already taking medication to lower your blood pressure, let your doctor know as in these cases Varimax may not be the best ED treatment for you.

Broken down into common, uncommon and rare, here are the side effects some men may experience when beginning treatment with Varimax.

What can I do about a headache after taking Varimax?

Whilst most men won’t experience the ‘Varimax headache’ it is still considered a very common side effect – occurring in about 25% of users. It normally happens when beginning treatment and most men find it goes away after the first couple of uses. Varimax isn’t alone in this, with most ED pills initially causing the occasional headache at first.

It happens because PDE5 inhibitors, like vardenafil, the active ingredient in Varimax, encourage your blood vessels to widen, and therefore blood flow changes in the brain. The result is headaches ranging from a mild, dull pain to migraines and cluster headaches. Headaches often begin less than an hour after you take Varimax but can also happen after the medication’s effects have worn off, potentially affecting sleep.

It’s possible to treat headaches from Varimax, limiting their intensity and how long they last. A few ways to avoid ‘Varimax headache’ include staying hydrated, avoiding alcohol, and eating a small meal or snack with your medication. If you frequently experience headaches after taking Varimax, your doctor might suggest paracetamol, which won’t interact with Varimax, and will be safe to use at the recommended dose.

If you experience bad headaches or migraines and feel as though they’re just not tolerable, or they’re negatively affecting your overall sexual experience, ask your doctor about lowering your dose as data shows that headaches are linked to higher doses.

What should I do if I get side effects on Varimax?

Let your doctor know if you experience any side effects when taking Varimax, they will be able to discuss them with you in detail. Together you and your doctor will be able to evaluate whether you should continue with your prescription, lower your prescribed dose or change medication.

Many men with ED find that milder side effects will go away after several goes with Varimax. This is because your body can become less sensitive over time. However, if you experience side effects such as chest pain, altered heartbeat, seizures, swelling, breathlessness or an erection that lasts more than four hours (priapism) – these require immediate medical attention and you should go to the hospital right away.

Can I lower my risk of side effects on Varimax?

Once you receive your prescription, remember to read the patient information leaflet. Yes, it’s long and you may feel you’ve read up on everything there is to know, but the leaflet will give you instructions on how best to take Varimax, and it’s good to have it in front of you in black and white.

If you’re not taking any other medications which are known to interact with Varimax the main thing to avoid will be grapefruit juice. Grapefruit juice can enhance the effects of Varimax, increasing the chance of side effects, and so it’s a good idea to avoid it.

Varimax warnings: What you need to know

The first step you can take to keep your risk of side effects as low as possible will be at your initial consultation. Ensure you give your doctor your full medical history including any medication you take or medical conditions you may have.

Some medication and medical conditions will mean that Varimax isn’t the best ED treatment for you, your doctor will know what these are. Giving them all the information you can allows them to make the best decision for you and will lower the chance of you experiencing any side effects from your treatment.

If you do experience side effects after you begin treatment, let your doctor know, they may consider lowering your dose or switching you to a different ED medication.

Which medications can cause Varimax interactions?

Varimax, or vardenafil, the active ingredient in Varimax, may interact with nitrate drugs, antihypertensives and alpha-blockers, which lower blood pressure. It’s important to let your doctor know at your initial consultation if you take any of these medications as it may mean that Varimax isn’t the best option for you.

Other vardenafil interactions include antidepressants, antibiotics, antifungals, medications for a prostate disorder, and HIV/AIDS medicine. Again let your doctor know if you take any of these before beginning treatment with Varimax and let them know if you start taking them once you’ve already begun treatment.

I have pre-existing conditions. Can I still use Varimax?

There are a few pre-existing conditions which may mean your doctor will need to closely monitor your progress when being treated with Varimax. Or they may indicate a lower dosage starting point, these include:

  • Irregular heartbeat
  • Inherited heart diseases
  • Peyronie’s disease (where the penis is curved)
  • Sickle cell disease
  • Multiple myeloma
  • Leukaemia.
  • Stomach ulcers
  • Bleeding disorder (such as haemophilia).

If any of the following applies to you it may be that you cannot take Varimax and you must tell your doctor at your consultation:

  • Severe heart or liver problems
  • If you are having kidney dialysis
  • If you’ve recently had a stroke
  • If you’ve recently had a heart attack
  • If you have low blood pressure
  • If you have a family history of degenerative eye diseases
  • If you’ve ever had a condition involving loss of vision

Who shouldn’t use Varimax?

If you’re allergic to vardenafil or any other ingredients in Varimax you shouldn’t use it. Signs of an allergic reaction include a rash, itching, swollen face, swollen lips and shortness of breath, so if you experience any of these let your doctor know immediately.

Varimax is not approved for men under 18 years old and may also not be suitable for men over 75 years old, your doctor will be able to judge if Varimax is suitable for you. If you take any medications that may interact with vardenafil, such as nitrate drugs for chest pain, then it’s important to let your doctor know as these taken with Varimax can dangerously affect blood pressure. Again, it may be the case that you shouldn’t use Varimax and another ED treatment will be more suitable.

Varimax atrial fibrillation is when the heart rate is irregular and often abnormally fast after treatment with vardenafil. It’s a rare condition with only a handful of case studies and normally occurs in healthy men with no history of erectile dysfunction who have taken Varimax. So if you don’t have ED, you should not take Varimax.

What if my health changes when I’m taking Varimax?

Let your doctor know. If you’re prescribed a new medication that you weren’t taking when you first started with Varimax it may interact with it. Equally, if your health changes, discuss this with them too.

Your doctor will be able to judge whether Varimax is still right for you, whether lowering your dose may be an option or whether a different ED treatment would be better.
