As long as you have erectile dysfunction and it’s safe for you, you can use Viagra. Viagra should be safe for you as long as a doctor or pharmacist has checked beforehand and agreed you can take it.
Viagra can be dangerous for some people with underlying health conditions. And this is why it’s important to be completely honest and accurate when giving your medical history during an assessment.
Health conditions that can make Viagra unsafe include:
- if you have or have ever had heart problems, including a heart attack
- an irregular heartbeat
- chest pain or angina
- heart failure
- having had a stroke in the past 6 months
- kidney disease
- liver disease
- high or low blood pressure
- penis conditions (like priapism) and sickle cell anaemia
- eye problems
Viagra can also be dangerous for you if you take other medications, like nitrates which are often prescribed for chest pain or pulmonary hypertension. If you take medications for these conditions along with Viagra it can cause your blood pressure to drop to an unsafe level.
Common medications that can make Viagra unsafe include:
- nitrates (including amyl nitrites or ‘poppers’)
- guanylate cyclase stimulators, e.g. Adempas (Riociguat)
- alpha blockers, e.g. tamsulosin
- HIV protease inhibitors, e.g. ritonavir, Crixivan, Fortovase, or Reyataz
- oral antifungal medications, e.g. Nizoral or Sporanox
- antibiotics, e.g. clarithromycin, telithromycin, or erythromycin
- other medicines to treat high blood pressure
- other medications to treat erectile dysfunction
- Revatio, a drug used to treat pulmonary arterial hypertension – this contains the same active ingredient (sildenafil) as Viagra
- other PDE5 inhibitors, e.g. Adcirca or Cialis (tadalafil)
Viagra can be dangerous if you overdose or take it together with illegal drugs. Alcohol and marijuana (cannabis) can make you more dizzy and can cause extra health complications when taken with Viagra. Amyl nitrites (poppers) can also make serious side effects more likely.
