What CBD dose should I start with?

Start at 5–10 mg per day and increase every three to four days until you reach the desired effect ("start low, go slow").

How many drops are 10 mg of CBD?

With a 10 % oil one drop holds about 5 mg — so two drops; with a 5 % oil you need four.

How fast does CBD oil work?

Sublingually after 15–45 minutes; swallowed only after one to two hours, but with longer-lasting effect.

Can I combine CBD with medication?

Only after medical advice — CBD inhibits liver enzymes (CYP450) and can affect blood thinners, antiepileptics and other drugs.

Complete CBD dosing guide: body-weight formula, drop calculator, use cases sleep/anxiety/pain, drug interactions — for Switzerland.

How many drops of CBD oil per day? How long until CBD works? And how do you dose correctly for sleep, anxiety or chronic pain? This guide gives you a clear formula per body weight, indication-specific recommendations and the golden rule for safe titration — across CBD oil, flower, capsules and vape.

TL;DR — CBD dosing formula

Starting dose: 0.25 mg CBD per kg body weight, twice daily
Titration: increase 25 % every 3–4 days until effect
Max everyday dose: ~1.5 mg/kg per intake (epilepsy exceptions much higher, doctor-supervised)
10 % oil: 1 drop ≈ 3.3 mg CBD
Onset: sublingual 20–40 min, oral 60–120 min, vape 5–10 min

The golden rule: Start low, go slow

CBD is well tolerated but individual response varies enormously. The WHO (2018) classified CBD as safe and non-addictive — still, never start with a high dose. Ideal sequence:

Take the starting dose for 3–4 days (body adapts)
Observe effect (sleep, mood, pain, side effects)
Increase 25 % if needed
Find your optimum — stay or slightly reduce

CBD dose by body weight (table)

50 kg: 12–15 mg CBD (~ 4–5 drops of 10 % oil)
70 kg: 17–20 mg CBD (~ 5–6 drops)
90 kg: 22–25 mg CBD (~ 7–8 drops)
110 kg: 27–30 mg CBD (~ 8–9 drops)

CBD dosing by use case

Sleep

Medium dose, 30–60 min before bed: 15–40 mg CBD. Combined with CBN and myrcene-rich strains, effect is stronger — sleep guide.

Anxiety & stress

Low-to-medium as needed: 10–30 mg CBD. Higher doses can paradoxically reduce effect — anxiety guide.

Chronic pain

Higher doses, regular: 30–80 mg CBD per intake, 2–3× daily. Full-spectrum oil often superior — entourage guide.

Inflammation & recovery

Medium maintenance: 20–50 mg CBD, 2× daily — sport guide.

Epilepsy / serious conditions

Doctor-supervised only — doses up to 25 mg/kg (Dravet syndrome: Epidiolex approval based on 10–20 mg/kg daily). Never self-adjust.

CBD oil · flower · capsules · vape — dose conversion

Bioavailability varies strongly by route:

Sublingual (oil): 13–35 %, onset 20–40 min
Oral (capsule, edible): 6–19 % (first-pass), onset 60–120 min, longer lasting
Inhaled (vape, flower): 30–56 %, onset 5–10 min, shorter
Topical (cream): local, barely systemic

Practice: if 20 mg oil works well, you need ~40–60 mg as capsule for the same effect — but with slower, longer profile.

Drop calculator: worked example

Standard pipette delivers 0.05 ml (1 drop). A 10 ml bottle = 200 drops.

5 % oil: 1 drop ≈ 1.7 mg CBD
10 % oil: 1 drop ≈ 3.3 mg CBD
15 % oil: 1 drop ≈ 5.0 mg CBD
20 % oil: 1 drop ≈ 6.7 mg CBD
25 % oil: 1 drop ≈ 8.3 mg CBD

Interactions & medications (YMYL — check with doctor)

CBD inhibits liver CYP450 enzymes and can alter these drug classes:

Blood thinners (warfarin) — bleeding risk
Antiepileptics (clobazam) — potentiation
Immunosuppressants (tacrolimus, ciclosporin)
Certain antidepressants (SSRIs)
Beta-blockers, calcium channel blockers

Rule: on prescription meds → ask your doctor first. Grapefruit test: drugs with grapefruit warnings almost always interact with CBD too.

Dosing for pets

Dogs & cats: start at 0.1 mg CBD per kg, twice daily. After 1–2 weeks possibly double. Only use pet-certified, THC-free products. Cats: extra care — sensitive liver.

Common mistakes

Starting too high: side effects, expensive, no better result
Giving up too early: effect often builds over 1–2 weeks
Untested products: without CoA nobody knows the real CBD content
Full-spectrum & driving: trace THC can trigger tests at very high doses — broad-spectrum when in doubt
Empty stomach: fatty meal boosts absorption 300–400 %
