Doses of 15 to 20 mg cause abdominal pain and also commonly diarrhea. Tachycardia and increased blood pressures occur as well. Subjective effects include dizziness, headache, and depressed feelings. LSD-like effects including dilated pupils are not uncommon. One subject given 15 mg had urinary retention for 12 hr, followed by difficulty in urinating for another 12 hr. So altogether, this compound has strong effects on smooth muscle. [...] 98. Murphree, H. B., and R. Bircher: Unpublished Data.

[...] 4-Hydroxy-α-methyltryptamine [...] Addition of a hydroxyl group in the same position, carbon 4 of the ring of α-methyltryptamine (Fig. 4), caused a marked increase of effects on smooth muscle (Murphree and Bircher, personal observation). Oral doses of 15—20 mg caused abdominal pain and commonly diarrhea. Two subjects experienced difficulty urinating. Other effects were very much like those of lysergide: dizziness, headache, and depressed feelings, as well as dilated pupils and some increase in heart rate and blood pressure.

It is reported to be markedly visual in its effects, with some subjects reporting dizziness and a depressed feeling. There were, however, several toxic signs at doses of 15 to 20 milligrams orally, including abdominal pain, tachycardia, increased blood pressure and, with several people, headache and diarrhea.
