Erectile Dysfunction (ED) and cannabis (marijuana, THC)
As cannabis becomes legal or decriminalised in more jurisdictions, the practical question of combining it with prescription medication comes up regularly. Erectile Dysfunction (ED) (Erectile Dysfunction (ED)) and cannabis share several pharmacological pathways, and the combination at 20mg, 100mg, 10mcg, 20mcg, 40mcg is not automatically benign even where both are legal.
How cannabis affects Erectile Dysfunction (ED)
THC and other cannabinoids are metabolised partly by hepatic CYP enzymes, including CYP3A4 — the same pathway used by many Erectile Dysfunction (ED) medications. Frequent cannabis use can shift the metabolism of Alprostadil, Avanafil, Dapoxetine, Sildenafil Citrate, Tadalafil, Vardenafil mildly. THC also has cardiovascular effects (increased heart rate, blood pressure changes) and central nervous system effects that can stack with Erectile Dysfunction (ED)'s side-effect profile.
Practical guidance
Occasional moderate cannabis use is unlikely to cause clinically meaningful problems for most adults on Erectile Dysfunction (ED) at 20mg, 100mg, 10mcg, 20mcg, 40mcg. Heavy daily use, edibles with high THC content, or cannabis combined with alcohol substantially raise the risk of dizziness, hypotension, impaired judgement and amplified side effects from Alprostadil, Avanafil, Dapoxetine, Sildenafil Citrate, Tadalafil, Vardenafil. According to the prescribing information, the full list of recreational substances should be disclosed to the prescriber.
Frequently asked questions
Can I use cannabis while taking Erectile Dysfunction (ED)? ▾
For most adults at 20mg, 100mg, 10mcg, 20mcg, 40mcg, occasional moderate cannabis is tolerated, but heavy daily use is not advised because of metabolic and additive cardiovascular effects with Alprostadil, Avanafil, Dapoxetine, Sildenafil Citrate, Tadalafil, Vardenafil. The safe practice is to mention it to the prescriber.
Does CBD interact with Erectile Dysfunction (ED)? ▾
CBD inhibits several CYP enzymes including CYP3A4, which can raise plasma levels of medications that go through that pathway. For Erectile Dysfunction (ED) specifically, this depends on whether Alprostadil, Avanafil, Dapoxetine, Sildenafil Citrate, Tadalafil, Vardenafil uses CYP3A4. Daily high-dose CBD products warrant a pharmacist check.
