I noticed that headaches are a potential side effect of Singulair. I wasn't prepared for the non-stop headache that I've had for about a week now. Does anyone know if this particular side effect is something that tends to go away once one gets used to the drug, or if it's persistent?
I seem to also have gotten a more rare side effect--nosebleeds. This drug is shaping up to be generally not a good time to me. Kind of a shame because it seems to be working quite well.
